  • German Engineering at its finest! H&K Rules!

  • Buy a Bulgarian AK-74 kit for 280$, assembly instructions are on YouTube. Mount Red-Dot, cheek rest, recoil buffer, cheap 5.45 ammo, and you'll be satisfied, guaranteed.

  • But will it blend?

  • i want a heckler and koch shirt

  • Love their reputation for making things - we should get that good rep back. Yeah, the US may make great aircraft carriers and air ships, but I mean even the small things. PAR.- The U.S. needs to take a look at the kind of schools they have in Germany, and the kind of social system that makes them all aware they're part of Germany. The HK47 is supposed to be able to endure anything, sea water landings, being buried in the desert.. Germany came out of defeat in WW2 and is now like a "better U.S."

  • Info for DDTea - Got my HK MR556 (civilian version of the 416) for about $2500. Came with a 30 round HK steel magazine. Does not work with polymer PMAGs. Suppose to work with EMAGs. The upper is advertised to work on non-HK lowers. Have about 500 rounds through it with flawless function. If you want the best, i think this AR is right up there. Just ask Seal Team 6 and Osama.

  • Killed Osama with it.

  • ok wat about -40 ºC ? after emerging from salt water..

  • Let's market another piston AR, but invest way more in our PR than the other companies! Then we'll convince civvies to pay $3500 for the neutered version we hock on the US market. It will come with an ULTRA-RELIABLE ADVANCED POLYMER 10 ROUND SINGLE-STACK MAGAZINE. It's too awesome for any AR-15 lower receiver, so we won't cut it to fit on anything but OUR OWN RECEIVERS. HK: Because you suck, and we hate you. Come on guys, let's face it: there's nothing special about this gun.

  • is there any way for a civi to own one of these babies?

  • German the Leaders of the Firearm Industry

    Germans made the first assault rifle

    Germans made the first modern SMG

    Germans made the first machine pistol

    Germans made the first AR-type rifle that is actually reliable

  • @lamestbiokinectic Germans make outstanding firearms. There is no denying that.

  • @lamestbiokinectic None of that is true

  • Ahh! German quality!

  • it looks like the m4/m16 if i were the army thats a big waste i go for something new like that xm8 just a little more funding and i'm sure they would of fixed the bugs on it

  • @xXmoemoneyXx the xm8 isent even close to the 416. im sorry but you did notice that the hk416 is the number one assault rifle in the world.

  • @rimacho14

    Xm8, Scar-L, ACR, XCR, berretta ARX160 technically, Barrett rec7 (6.8 SPC) outperform the HK416. Hk416 is just a piston driven AR15, and surely not the best on the market. (LWRC, LMT, Larue,

    it has been adopted by SF because it doesn't require additional training since it share the same base and handling than the M4.

  • @xenomorphelv426 It's been adopted because it's one of the two best piston ARs on the market. The only other piston AR that is as good is the LWRC M6A2, it may be being used as well. Larue doesn't make a piston AR. The XM8 has a bad habit of melting under sustained fire, it also doesn't have rails. The RobArms XCR is a shit pile, plain and simple. I can't speak for the ARX160. Barrett's REC7 is not quite as good as the piston ARs from HK and LWRC.

  • @Nater245689 HK416 only bring Piston mechanism. not more. it still has the same limitation than any other AR platform.

    you say ACR has a funky safety ? i don't agree. it just need adaptation. ACR outperform by far any AR plateform. reliability is a least as good, it has lots of new features.

    Anyway, the most advanced Assault Rifle still remain the Berretta ARX160: Fully ambidextrous: (charging handle, side ejection, mag release, selector, quickest barrel change (2 seconds).

  • @xenomorphelv426 What limitations are those?  The only real downside to the AR design is the receiver extension, but folding buttstocks are of limited utility anyway.

    Before Youtube fucked the profile system, I believe your profile said you lived in a country that wasn't the US. In which case, you've never touched an ACR, and you'd not know how annoying the safety selector is. Not a big problem, but a problem.

  • @Nater245689 charging handle position sucks, there is no ambidextrous fire selector, neither mag releaser, bolt releaser. all these features come as standarts for next gen rifles. This is why exepted the piston modification the HK 416 is a limited upgrade.

  • @xenomorphelv426 You don't have much experience with real firearms, do you? All those features can easily be added to an AR. The charging handle position isn't ideal, but at least it doesn't reciprocate.

  • @xenomorphelv426 Not to mention, you rarely use the charging handle on a rifle with a bolt catch/release. The only time you use the charging handle is during malfunction clearance, in which case you're going to have to break your cheek weld and the charging handle position is now quite convenient.

  • @xenomorphelv426 Color me unimpressed by the Beretta. There is no reason a rifle manufactured in the 21st century should have a reciprocating charging handle, yet it does. Making a fully ambidextrous lower is not rocket science, it can and has been done for the AR. Ejection has never been a problem for me when shooting left handed, or anyone else, that's what the brass deflector on an AR is for. Being able to switch sides is nice, but not really important at all.

  • @xenomorphelv426 Furthermore, the quick change barrel system is absolutely unnecessary and will not be used in the field. The only thing it does is decrease the weapon's durability. It's much more tactically sound to change an entire upper receiver (with pre-zeroed optics and accessories) than swap barrels for different missions. Not that this really happens, the units with that degree of latitude simply have access to multiple primary weapons depending on their mission.

  • @xenomorphelv426 The ACR has a funky safety, it really sucks and needs to be fixed. Not to mention it's a Bushmaster product. Magpul should have kept it in house. The SCAR-L is very good, but it provides little benefit over either DGI or piston AR-riles and a lot of downsides (less rail space, reciprocating charging handle). The SCAR-H is dramatically superior to any 7.62x51mm rifle you can get, I'll give that to FN.

  • @Nater245689 the beretta ARX160 has my favors.

  • @xenomorphelv426 Why? I don't think it's been in service long enough to really comment on it. A lot of rifles with polymer lowers have problems with trunion shift during prolonged firing, causing wandering zero issues. It has a reciprocating charging handle. No modern rifle should have a reciprocating charging handle. I've never fired one, so I can't comment further. If it were available for purchase, I don't think I'd really look at it, though.

  • @Nater245689 Berreta doesn't use the same polymer than HK. and sensitive part are still from steel composition.

    the reciproating CH on the ARX doesn't change anything. recoil and control are exactly the same than non reciprocating.

  • @xenomorphelv426 It's still polymer, it's still more sensitive to heat than an aluminum forging. The Beretta may not exhibit trunion shift, but then again it's possible. Have you ever fired a rifle like this? Apparently not, else you'd know how annoying a reciprocating charging handle can be. It has nothing to do with recoil, I don't know why anyone would think that it did.

  • @Nater245689 reciprocating charging handle is moving parts. on some weapon (ak47, m14...etc) it affects a lot the shot stability (often refered to have the same issues than recoil). but on the ARX160 the reciprocating charging handle doesn't move more than non reciprocating systems. the moving part make short move path with very few mass displacement.

  • @xenomorphelv426 A reciprocating charging handle has no perceivable effect on felt recoil. None. Your post also makes zero sense. A non-reciprocating charging handle does not move, so by definition a reciprocating one is going to move more. The problem with reciprocating charging handles is that they cause problems shooting around barricades.

  • @xenomorphelv426 I see you deleted your last post, likely because it was false. There is not civilian G36...there is the SL8 but it's not really that close to the G36. There is no civilian FAMAS, at least not in the US. Century Arms did import about a dozen of them, but I highly doubt you've shot one.

  • @Nater245689 it's not G36, it was FN Hertsal FNC.

    there is civilian Famas. (I live in France)

  • @xenomorphelv426 Big difference. Aren't those weapons highly restricted? My French isn't so good, but it appears that they'd be class I or class IV depending on their chambering (5.56x45mm NATO or .223 Remington).

  • @Nater245689 semi auto are class IV in France (defense weapon available with sporting licence since more than a year + prefect authorization ) all chambered for .223 (5.56 is forbidden)

  • Comment removed

  • @rimacho14 XM8 is more reliable than Hk416. 126 stoppages vs 233 for 60 000 rounds fired..

  • @xenomorphelv426 HaHA.. you sir, do your research like me, yu got that from the military dust testing right?? nice

  • @xenomorphelv426 .3% vs. .2% is well within any error margin. They ran the test again, this time with a factory fresh Colt M4A1, and all rifles experienced malfunctions around .3%. Of course, you won't see that on the Wikipedia pages for the XM8 or 416 since they're maintained by HK fanboys. An additional .1% malfunction rate is probably worth it for a rifle that won't melt.

  • @Nater245689 the source is not from HK, it comes from the official Us Army test procedure. Colt M4a1 is mechanically more tended to jam. reports in duty confirm it.

  • @xenomorphelv426 The source is from the US Army, who was really pushing to buy the XM8. They rigged a test with a worn out M4. It shouldn't be taken as gospel. Actual combat reports have shown the M4, and the M16FOW in general, to be quite reliable. There is a reason why the weapon system is used by just about every Western military unit that has some degree of latitude in choosing their equipment.

  • Best assault rifle until today

  • God bless those ****ing germans.

    Your cars and your guns, we salute you gentlemen.

  • This is MADE IN GERMANY! :-)

  • So they added a piston to an m4..

  • @xGothimox thats almost exactly what it is. There are lots of piston uppers on the typical m16 platform, but this one looks sweet! and costs at least twice as much

  • @xGothimox this is designed from the bottom up, the m4 is a redesgined m16. they made this rifle for the competition for the us next combat rifle. thats why its exterior is exactly the same as an m4(like really exactly the same, all the switches and triggers are at exactly the same place) so it would be easy for the soldiers to go over to this rifle.

  • Great gun, just make it in 6.8SPC or 5.45x39!

  • I want one! With a 14.5" barrel!

  • Germany you fucking rock

  • what a sik gun, no overheating, cool and will not jam , how epic.

  • Lol, there's the key phrase in this.

    "The government is sparing no expense to TEST these weapons"

  • Those krauts sure know how to make a weapon

  • HK makes the best guns, there kind of douchebags when it comes to letting other countries use them, but if you ever get your hands on one, you'll never let it go.

    just find a way to move the charging handle to the middle of the gun, and bam! you have the perfect gun.

  • nice quality!:)

  • H&k suck on the civilian market

  • MADE IN GERMANY OWNZ!

  • Vorsprung durch technik-

    Thank you germany!

  • We here in Norway are very pleased with the HK416. So far it lives up to the expectations. The only problem is the environmental- friendly ammunition, witch cause allergic reactions for someone. But i think they will sort it out. The gun itself, delivers.

  • i think hk is the best gun company they make the coolest guns

  • H&K is the best all-around gun manufacturer; but thats my opion. they have at least one design for each classification of gun.

  • When did this show air on history channel? Cause last I remember testing for the xm8 was cancelled back in 2005.

  • @acepilot121 You can watch this whole thing, its called High Impact M16 history. Its on youtube in five parts.

  • price? is there a model with a longer barrel?

  • @antwan17 2700 EUR (3800 $US) at a HK distributor, 16.5" barrel. Perhaps if you buy it directly in Germany you can save a couple 100 EUR.

  • @antwan17 Yes, theres also a 14.5 16.5 and 20 inch i think.

  • Made in Germany. Good thing they're on our side ;)

  • apparently both SCAR and XM8 performed better than the 416 in a torture test

  • many people like the ak47 but i like this gun more than the ak47... a lot more

  • 1:06 "Always cool to the touch" 1:07: Picture of smoke coming out of the gas block. Hah. Sure, the bolt is cool, but the handguard is going to get HOT. Notice how he kept his support hand far away from the front. Still, reducing heating/cooling cycles on the important parts is important.

  • hey can you upload the hole episode please?

  • does anyone know how accurate the hk417 is?

  • @bangmeister Marginal 1 MOA

  • Im thinking about getting one....cant decide weather to buy a SCAR H or the 417 :-/

  • @Raccoonraper hk 417

  • I'd choose this if i were in battle.

  • Fuckn Sweet!

  • germans are the best

  • I want one!!!!

  • Whoever arms the us military is retarded but all I can say is that if I had to fight I would use the hk 416

  • i want to see some hk417 action vids .

  • made in germeny

  • Im pretty sure the Remington ACR/Magpul MASADA will surpass the hk416 but remember:

    "Never forget that your weapon was made by the lowest bidder."

  • Does this use the same ammo as the m16?

  • @ub3rn00b6

    This weapon can fire all 5.56 mm ammo

  • Das System ist eigentlich alt bekannt.. Hat die stg77 bzw steyr Aug genau das selbe nur die mods sind nicht so reichhaltig...

  • kind of hard to have the 416 compete against the xm8 due to the fact the same company makes both

  • someone tell me why the m16/m4 is still standard issue if these weapon systems are superior as shown? plus they say that the us is looking for new rifle, why do we not change it

  • @DropOnYa i myself have asked the same question time and time again,a nd the only answer i can come up with is cost of these new guns, it's no secret the standard rifles the armed forces use now are cheaper than these and from their perspective i'm guessing easier for manufacturing

  • @DropOnYa "It ain't from around here."

    Plus, if anything, USA should adopt the FN FAL for riflemen - or at least revert back to the M14.

  • 0:58, sounds a lot more like 850 rounds per minute fast..

  • not a big fan of the scar design, looks bulky, slower firing rate, etc. I much prefer the acr or hk 416, and no, i'm not talking about mw2...

  • Problem with this gun it's expensive and HK417 is even more expensive that is pretty much why ACR takes the future and HK416 takes the spec ops situation.

  • the fuck? you are telling me that THIS was invented for that weapon NOW? what the fuck we've been doing since ever automatic weapons started being made?

  • Wait just to make it clear i dont support the masada because its in MW2 its i knew about it b4 it came out but yes the scar series is good but not many troops use them i do believe some rangers are useing them

  • quality made in germany !

  • favourite :)

  • Makes me proud that US Troops are going to use german rifles in the future. :-))

    Good old german Engineering

  • I /agree, the germans are good at this kind of shit. Mercedes and H&K ftw.

  • @IcebergPhil I would say the Barrett Rec-7 is more likely

  • There should be no excuse for not sending this weapon to our troops. I mean really, we can afford the world's best fighter jets and tanks, but we field obsolete rifles.

  • I think the next generation weapon should be the magpul masada (ACR)

  • @kyle1x9

    Funny how the ACR suddenly became "teh best gun evar" after MW2 was released..

    The SCAR series (especially the H version) is probably better.

    But really, I would prefer a G3/FAL over any other gun anyime.

  • The G3 is really a gun that is super hyped. Idk if you have shot one IRL but its not nearly as reliable as some other weapons out there. You also need ape arms to use and control it properly.

  • @Kevin32001

    I have, not an "original" though, a full auto HK91.

    The whole reliability issue has only been with all the M4/M16 anyways, most guns after WWII were developed especially to cope with extreme conditions as a result of experiences in russia and wherenot. G3 does over the beach and the whole "covered in sand" thing which is pretty much the worst the gun will encounter if you don't plan on using it as tires for a tank.

  • I'm athletic but no gorilla and I managed it just fine.

    Really just a matter of getting used to and not beeing a pussy.

    I shot ...phew...loads of rounds with it and only cleaned it once and It never jammed.

    That's reliable enough for me:D

    Also, it was from the ground up designed to work under all conditions, a lesson learned through WWII

  • tar-21 is better...lol jk but i do prefer

  • @nero91 because everyone thinks lifes a video game. There dumb asses...

  • I wished this gun had ACR stock how it's more custom to confort but if they got the stock on, it would be impossible to cock it.

  • so Im stuck between buying a Ruger SR556 and the HK MR556, i thought i read somewhere the HK can use only certain magazines, Can you use any AR15 mag with these? and if not do they make a 30rd mag for the MR556?

  • I might be wrong but the mr556 isn't even out yet, have you checked out the FN SCAR? Believe it or not it did much better in the Army testing, it's a much more oringinal design. and it's more adaptable...other than that LWRC makes great self regulating gas piston ar rifles at about half the price of HK's plus they stay away from propriatory systems crap.

  • Recoil has everything to do with the amount of weight thrown back, the piston comes back half an inch and comes back forwards before the weight of the bolt comes all the way back to transfer the momentum into your shoulder. So the piston shouldn't affect the recoil in that way. Although to me it seems it increases the speed at which the bolt shoots back which does affect momentum. 416 weighs quite a lot compared to other modern rifles and that does reduce the recoil as well.

  • @TomsGuns It should reduce the recoil even more with the short barrel & the extra weight but it doesn't.The HK also has a stiffer buffer spring as well & a heaver buffer too.For improved cycling thus it's a bit harder on the recoil.

  • Heckler & Koch= Friggin Geniuses.

  • our soldiers need SCAR-H's in their hands.

  • at 1:08 when he puts a new mag in it looks like he hits a button or a switch on the right side of the weapon. can someone tell me what he is hitting? its also in cod modern warfare when you reload the m4/ m16 and i have always wondered about it. thanks

  • It's a bolt release catch. By pushing it, the bolt comes forward again, and will cycle a round in the chamber.

  • many thanks

  • i never saw this, great video quality 5/5, thank you for posting

  • Best rifle made.

  • good job HK

  • Wait a minute... didn't HK design both the HK416 and the XM8? The XM8 is basically a G36 with redesigned furniture, but the gas system is basically the same.

  • yup and the bolt is better but it has the old magazines witch the xm8 has. so if the hk416 has the new magazine it would beat the xm8

  • @kalamarikahunalord

    Yes they did. And as the saying is: "Never change a working system!"

  • What's the hole under the Gas Block for? It's also on the HK MP7A1..

  • I'm not sure, maybe it's for a sling attachment?

  • Maybe not, because the sling swivel is under the front sight hinge. It's weird because it's a huge hole and too far in to mount something trough it..

  • @Ralfst3r the sling is attached to the picatinni rails

  • i guess HK made it so...

  • @Crim15 If I'm looking at the right hole I'm guessing it's part of what the quad rail mounts to

  • @viperboost931 Actually the Quad-Rail Hanguard is connected to the barrel nut, it doesn't touch the barrel at all. The Hole I'm asking about can be seen clearly at 0:23 at the bottom of the gas block..

  • @Crim15

    its one of the strategically placed holes that allows the weapon to lower pressure in the mechanism. Its one of the holes the water can escape out of so the gun wont explode. I think they talk about the holes in the video

  • @MrGunsplosion101 I don't think so. The Drain holes on the HK416 is mostly the same as that on an M4 SOPMOD Kit except the 416 has channels between wider spaces winthin the receiver. The only holes in the barrel are the breech, gas tap and muzzle and the only drainage on the barrel peice is a dyke in the chamber breech. I'm talking about the one under the gas block..

  • @Crim15

    OHHHHHHHHH THAT hole,

    thats for a Quick detachment sling point

  • @MrGunsplosion101 Again? 8| With the Quad Rail on it's not much of a "quick detachment/attachment sling point". Same goes for the MP7A1(SP)..

  • @Crim15 Water drainage port.

  • @618Bdown Doesn't drain water from anywhere else other than the opposite side of the hole..

  • @Crim15 im not 100%sure what holes u are referring too... the two things that comes to mind is the bayonet mount, and there is a gas regulator switch there as well. for switching between silenced and normal.

  • @catbearlol The HK416's gas valve is fixed like the G36's..

  • @Crim15 what do u mean by "fixed" ? i dont know that much about the g36..

  • @catbearlol It can't be adjusted or switched between regular or supressed. If a supressor is used, the increased rate of fire and muzzle boost would have to be dealt with regularly..

  • @Crim15 i am fully aware that pulling a switch wont make a weapon silenced if thats what you mean.... however there is a gas switch for adjusting the amount of gas that will push the piston back...it has two modes: for when ur using a silencer, and for when ur not. :) i was issued this weapon in my two years of service in the norwegian army, iknow this.

  • @catbearlol I'm aware of that as well. Using a supressor on a rifle needs both a supressor, sub-sonic ammunition if needed, and adjusted gas regulator, not just flicking a switch or something.

    And back to my first inquiry. The hole I'm talking about is right behind the bayonet mount. I hope you can help me with this since you said you were issued this particular rifle..

  • @Crim15 i see now what hole ur talking about. ive never used it for anything so ur guess is as good as mine :P

  • h&k 416 has more recoil than the m4

  • wrong.

  • no when the piston recoils backwards it increases recoil, noticeably as i have shot both

  • I've heard people say it increases recoil or decreases recoil.

  • @mrfrankincense the recoil is exactly the same simply because of the same round beeing fired. However, the effect of the recoil can be different. meaning more energy can be dispersed over a shorter period of time.

  • @catbearlol The force is the same, the energy isn't.

  • I wish they would have done the test with a M4 and HK416 side by side.

  • Sure there is. For one, less heat = much longer lifespan. Also, they don't get dirty nearly as fast. That means less cleaning. Those two benefits apply to almost everyone.

    It's bad to have a tool that can take abuse? I didn't realize there was a mentality that functionality was a bad thing.

  • I forgot to add: I own a LOT (and I do mean A LOT) of firearms. I also like to shoot a good portion of them on a regular basis. Cleaning can be fun, until you have to clean a ton of weapons on a regular basis. I've grown to hate the smell of solvent (which smells just like the same shit I use at work to clean carbs).

    Not having to clean as often (aside from the barrel) is a huge plus for me.

  • whenhe said "if you think the sand is bad" i thought he was gonna say "try shit!"

  • ahahah... i though the same thing

  • it does

  • the recoil buffer spring on an AR, how much recoil does that reduce? also when you change the length of the recoil buffer tube (m16 to m4) does it change the rpm?

  • so basically, they took a M4 receiver and stamped H&K on it and added a gas piston and rotary sights. Innovative!!! When is someone gonna make a NEW gun and not just copy the AR?

  • If they were copying the AR's design, they wouldn't be using a gas piston. The gas piston greatly improves the reliability of the platform.

    One reason they're using an AR platform is so that their upper receivers will fit on pre-existing lower receivers that the military already has.

    You have to remember, they want military contracts; this model is NOT aimed towards the American civilian. For a long time, HK had no intentions to produce a semi-auto civilian version.

  • I understand all of that but the military is like everyone else, they like something new and different once in a while. And there are a lot of ARs with gas piston systems out there, although they are not quite as nice as this one they are just as functional. I just hate it that every has to copy the AR platform and not think for themselves. Sadly, innovation in the gun world seemingly died with John M. Browning.

  • The military has expressed no desire to adopt another platform. Companies like HK build to meet the demand of their larger customers. Unfortunately for civilians, HK has always directed their products to police/military use. You don't necessarily make money from being innovative, you make money from getting contracts. Having said that, this rifle has a very solid platform, and it works well.

    The military likes what's CHEAP. Replacing uppers while retaining existing lowers is a cheap upgrade.

  • there is very little cheap about anything made by H&K. Probably why the 416 is only really used by SF units or security firms with deep pockets.

  • I never said HK's products are cheap, and you're missing the point. Say you work for HK and you want to make a product that you can sell to the US military. Are you going to design an entire rifle, which will be very expensive (not a likely contract deal) or! Are you going to design an upper receiver that will fit on the customer's pre-existing stockpile of lowers? That is a cheaper upgrade in comparison to buying complete rifles from HK. That's why HK is using the AR platform as a base.

  • and you are missing my point. This is just another example of a general lack of engineering brilliance in the gun industry. It does not take much to modify someone elses design and make it better. Its still just another clone.

  • It's not a "clone". The original design had severe reliability and overheating issues. Newer designs have fixed these problems. The end result is a reliable and durable rifle. What's the problem? The whole point of a new design (which is what you're advocating) is to fix problems in previous technology that a previous design won't allow. There are now no problems with the AR. Why would a company spend millions of dollars on a new design when they don't have to? That's pointless and expensive.

  • correct but sometimes something new is needed to give an edge over the competition. If you keep making the same thing over and over and only slightly improving it, naturally the competition is going to adapt and make their stuff even better. I just want to see something other than a damn M4 or AR-15. Something new.

  • The new models are lightweight, durable, reliable and accurate, but your problem is that they're based on a system that's not new? If it does it's job well, what does it matter how old the original design is?

    I own an LWRC M6A3 DMR in 5.56 (similar to the HK 416 minus the select fire) and it's an outstanding rifle. I can't think of one feature I'd like to be improved.

    HK is not going to introduce a new design until they encounter limitations of the AR platform that can't be fixed.

  • the old models were lightweight, durable, reliable and accurate also. The problems with the old ARs came from the type of ammo used and the sever lack of cleaning they received in the field. The only problem they had then and still have now is that they lack the punch of a 7.62 round. Thats where the 6.8 comes into play though. I guess I'm just tired of ARs in general. thats all. but I do like the 6.8 platform thats out now.

  • The severe lack of cleaning is to be expected of a field used rifle. It's easy to say that "well, you should keep the rifle clean" when you're just taking your rifle to the range, but when you're in the jungle or the desert, sand/mud can get into your weapon while you're using it. Rifles need to be able to take severe abuse.

    The A1 was durable? Really? The bolts overheated so quickly it's not even funny.

    The A1s were trash. Many Vietnam veterans will quickly agree with that statement.

  • how is a steel bolt going to overheat? they have never changed out the bolt design for any generation of AR style rifle (except the AR-10s in .308 which had a larger bolt face). The same bolt in an A1 is the same one that the A4 takes today.

    more heat = more expansion = more wear = shorter lifespan

    The A1 is an example.

  • all of the M16 and M4s use a gas blowback system for military use (other than special ops units).  The most common market for the piston driven system is the civilian market because people buy it because its new and fancy and someone said it would work.

  • They DO work; that's why people buy them.

    The only reason the military hasn't adopted the 416 (or some other
