SureFire Muzzle Brake video

[SigmaAirsoft]

Will this brake be limited legal or open class only for 3 gun competitions?

[vic45redd]

I'm looking at the thumbnails on the right of this video and most of them say "muzzle 'break'". What is a "muzzle 'break'"? Wouldn't a rifle be unsafe to shoot if it has a break in its muzzle?

[ThunderTactical]

@vic45redd A muzzle break is a device, like a flash hider, that attaches to the end of your barrel and reduces muzzle climb and movement. It doesn't hide flash as well as a flash hider but allows for quicker follow up shots...It's not a ''break in the muzzle''. This particular muzzle break is also an adapter and allows the quick attachment of a Surefire sound suppressor.

[marktse]

@italianopiombo only if you get the 308 version of the compensator

[whatever7x7]

Holy crap his thumb is on top of the foregrip, can you say I'm going to hold this sucker down and pretend the muzzle brake is doing the job... lets see what it does sitting on top a bag on a bench rest.........FAIL

[drenM1A1]

JFC. I thought the comments on ARFCOM were stupid.....

[veilofpaya]

any one know who makes his rifle?? or the rifle barrel?

[kikostaro]

1:27 hahaha hack no recoil XD

[marktse]

can you guys make a fake suppressor version of the muzzle brake. Looks cool and yet gives the compensation aspect. I only ask because I have a 10.5 inch barrel that i want to make rifle compliant and I need a 6 inch permanently fixed attachment and i don't want to loose the benefits of the muzzle brake. I currently have t1 FA556s on my 16 inch ar. Also are there videos of the 308 version?

[lvKingCobravl]

how much u want for it?

or can i haz it?

[evh57]

@italianopiombo the 308 version would

[sasquatch4liffee]

are these legal in california?

[evh57]

@sasquatch4liffee yes, its a muzzle brake.

[eastofakron2]

what does a muzzle brake do? does it make the recoil less? does it make the gun louder? thanks in advance

[635574]

awesome, this and lasers is what modern shooters need(ofc here is more: like realistic ammo in mags or sounds or sound intensity or bullet physics and material interaction)

[635574]

awesome, this and lasers is what modern shooters need(of course here is more: like realistic ammo in mags or sounds or sound intensity or bullet physics and material interaction.)

your face is bumpy :P 0:22

[curseofa5r5a]

@moddingspree jajajaja

[monsword]

guys...if you'd ever got a chance to stand by someone shooting a 338WM with a muzzle break, PLUG YOUR EARS........:D

[REDGUNRIDER]

Brah.... You put dakine 808 Hawaii area code on da fone numba.

[CE750]

The problem with my muzzle brake on my weatherby .460 Magnum is that I trade the massive recoil for massive sound!

[OhshitPositive]

...why is "Help Me-Mandy Moore" #2 in the suggestions off to the right?

[HiramMaxim]

The Best Muzzle brake is NOT Surefire!

Its the PGRS-1 Muzzlebrake made by Bruce McArthur.2486253333

If you guys have ever seen the Movie "Shooter" the main rifle is the .408 Chey-tac Intervention. Chey-Tac Uses the PGRS-1 on all there rifles.

Type in "No Recoil or Muzzle climb with my M-16" in the search engine and there is a video of a M-16 being shot on Full Auto with one hand!

I have use one on my Ares SHRIKE 556 and on My .338 Lapua. It makes the Lapua seem like a .22lr

[Clementplatypus]

Straightjacket barrel system is better, they are still developing for every gun. But surefire is still really good. Teludyne tech

[pengukid]

Does anyone know if this muzzle break is sig 556 compliant?

[metalhead12f]

I bought one and its probably the best Muzzle Brake i have ever used.

[Nuclearfright]

Basically an AK74 muzzle brake...

[esh325]

@Nuclearfright, I don't know about that. Different shape then an AK-74 one.

[pioneerphill]

what is the difference between the brake featured (MB556K) and the MB556AR? besides size and mounting requirements. Quality?

[rawimpact]

that guy is pretty small.... or that ar15 is 2x bigger than normal for some reason

[blathy]

the 556 dont kick anyways. just trying to sell there shit

[OTHEGODFATHER]

the difference is shootability hahaahah

[CharlieDoan]

-Part time job for Machinists!

[maalaea]

does the military use this? if so why or why not?

[zillsbury]

surefire equals QUALITY!

[gatzANDfratrats]

Its either this or KAC break????

[Mikelaren101]

Uh anyone know what the purpose of the muzzle brakes with an object that looks like a bayonet on the end of some heavy weaponry?

[riflemanjim]

I think a lot of that speed shooting close range stuff is done with super light bullets

[Southern661]

Not really. Muzzle breaks take the pressure and use it to combat muzzle rise. The more pressure the round has, the same pressure is combating the muzzle rise.

[riflemanjim]

The reason a muzzle brake works is the gas pressure yes,the reason a muzzle brake is more effective on a 300 win than a 458 win is the fact that more of the recoil in the 458 comes from bullet weight.the heavier the bullet the more recoil,look it up.

[Southern661]

Recoil is generated by how much energy the gunpower transfers from its rapid chemical release of pressure- to the bullet.

[riflemanjim]

And it's also generated by bullet weight look it up.these competion shooters use lighter bullets for lower recoil like i said look it up.

[Southern661]

Recoil is strictly caused by the ammount of kinetic energy the gunpower transfers into the projectile. The gunpowder is the Potential enery, and when the firing pin hits the primer which ignites a spark which creates a chemical reaction that creates gases which transfer their kinetic energy into the bullet, giving the bullet kinetic energy which is felt when it leaves the barrel.

~50 Grains @ 2000 FPS

~100 Grains @ 1000 FPS. They will both have the same ammount of recoil.

Look it up.

[Southern661]

Bullet weight has nothing at all to do with recoil, its strictly the ammount of kinetic energy the powder transfered into the bullet.

Example;

.45 ACP - 230 Gr.

.357 MAG- 124 Gr.

The .357 MAG has more recoil.

Of course if the heavier bullet is traveling at the same speed of the light bullet, it will have more recoil, which gives the notion that 'heavy bullets mean heavy recoil', which is untrue.

(200 gr @ 1000FPS)>(100 gr @ 1000FPS)

Get it?

[riflemanjim]

your wrong,the 357 has double, the pressure yes.if you equaled the pressure in both rounds the 45 would have more recoil because of the heavier bullet,period.

[riflemanjim]

You assuming it takes half the powder which is a wrong statement,any site can verify what i'm saying your assumption is wrong you dont cut the velicity in half by using half the powder check any reloading manual.

[riflemanjim]

You can't take a round and double the bullet weight and cut the velocity in half it doesnt work like that period lokk at a reloading manual. a 110 grain 300 win goes about 3500 fps,by your logic a 220gr would go 1750 it just doesnt add up.go to answer muzzle brakes. their chart shows recoil reducuction in percentage the cartridges the are least effected by the muzzle brake are the 458 and 375 they have have bullet weight to powder cahrge weights,what take more effort to push heavy or light.

[Southern661]

"a 110 grain 300 win goes about 3500 fps,by your logic a 220gr would go 1750 it just doesnt add up" Well thats because of the case capacity. Who is talking about a .300 win, anyway? Sure the hell wasn't me.

We where talking about RECOIL. RECOIL IS GENERATED DIRECTLY BY THE AMMOUNT OF KINETIC EVERY THAT LEAVES THE MUZZLE! THATS FINAL!

You said the BULLET WEIGHT determinds the recoil, and i prooved you wrong. ITS THE AMMOUNT OF K.ENERGY THE GUNPOWDER CREATES!

[riflemanjim]

You tried to compare two different cartridges thats apples and oranges.i picked the 300 cause there are a 110 gr bullet and a 220 gr.Which is a direct comparison unlike your choices.A 110 grain bullet has more powder than the 220 and guess what the 220 recoils more,equal and opposit reaction,heavy bullet out the front more recoil out the back. Has little to do with case capacity you made the one half claim and your wrong.

[riflemanjim]

The majority of recoil comes from powder but all things equal competion shooters use light bullets for quicker sight picture recovery.you cant compare a 45 and 357 the 357 operates at double the pressure is you seated a 230 gr 357 it would not go half the speed period.

[riflemanjim]

I have one 220 load at 2795 fps 70 grains of powder. Ihave another load for a 110 that 3498 fps uses 83.3 gr of powder.those are numbers off a reloading site,your logic says that cutting the the bullet weight on the first load would double the velocity,look at the diffence in powder charges your theory doesnt work.Ill find the actual recoil numbers

[riflemanjim]

all things being equal if you loaded both rounds with the same amount of powder or even pressure the 220 has more recoil,more weight out the front the harder the rifle backs up period.and if you follow the load charts half the bullet weight doesnt double the velocity or the same load that pushes the 220 to 2950 the 110 would go over 5000 fps.

[Southern661]

@riflemanjim

I'm not talking about ANY cartridge here, I'm talking about pure psysics. Im talking about a projectile going x ammount of speed, not a .300Win.

The ammount of energy it takes to make a 100gr object reach 1000 FPS, is the same ammount of energy it takes a 50 gr object to reach 2000 fps.

[riflemanjim]

pure physics dont apply here you dont get half the velocity for ghalf the powder period any novice handloader knows that.check a reloading manual.

[Plur307]

@riflemanjim

Pure physics always apply. If the physics don't seem to explain what you observe then you are probably doing the math wrong.

[riflemanjim]

you guys are looking at numbers on paper vs reality.the fact is you put a bullet on top a powder charge all things being equal double the charge or half the bullet weight does not correspond with double or half recoil.the amount of powder to double velocity is far greater than double its original charge weight,funny thing calleed friction.

[Plur307]

double powder doesn't equal double velocity because energy goes up by the square of the velocity. It takes 4X the energy to go 2X the speed. Physics do account for what you are talking about.

[riflemanjim]

it is not linear what was being said was if you cut the powder charge in half you get half the recoil which isnt right

[Southern661]

@riflemanjim

I do believe you're just an argumentative person.

[riflemanjim]

I believe your someone with little to no experience with this subject if your formula was wrong your premis is wrong. when your wrong your wrong period. and your wrong.

[Southern661]

@riflemanjim

And you just keep believing that stationary objects create recoil, buddy.

[riflemanjim]

stupid the gunpowder doesnt even make pressure unless theres a projectile on top of it take the same powder charge add a heavier projectile on one and a light one on the other and guess what the heavier one has more recoil

[Southern661]

Once there was a bullet, and then God said "let there be pressure", right?

when the firing pin hits the primer the heat and flame is exploded into the gunpowder creating a rapid decompression of the solid matter into gases.

147 Gr. 9mm vs 125 Gr. .357 MAGNUM.

the ammount of energy transfered into the bullet exiting the barrel decides the energy/recoil.

[riflemanjim]

you dont get it the heavier the bullet over the same charge means more recoil periodthe bullet does determine recoil period

[Southern661]

a 9mm is a .33 and a .357 magnum is a .35. Both have almost the same diameter but one has more (what) behind it that makes one recoil greater than the other?

A) Bullet weight.

B) Brass.

C) primer.

D) Gunpowder.

[riflemanjim]

Newton's 3rd Law which basically states, 'For every action there is an equal, but opposite, reaction'

The recoil is the opposite reaction to the bullet being fired forward.

period

[Southern661]

Well yeah you got that down pat, but i think you're missing a vital key to why exactly the bullet was fired (pushed) forward once you pulled the trigger.

I want you to not fire your rifle and see how much recoil it has, and then fire it (ignite the gunpowder infront of the primer) and then see there is any difference in recoil.

[riflemanjim]

on chuckhawks page the second sentence reads. Recoil is caused by two factors. The first is the bullet itself, which cannot be interfered with. The second is the expanding powder gasses thats the end game period your comparisons are wrong.compare appales tom apples,you cant even use those rounds cause the weight of the gun itself effects recoil.

[Southern661]

Why do cartridges have gunpowder?

[riflemanjim]

your not getting it read what the experts says on their own page they flat out say and is proven the first thin the the bullet weight period your argument was 50 gr at 2000 has the same recoil as a 100 gr at 1000 doesnt work like that period your wrong.

[Southern661]

Well, Jolly-gee, if you read back I had apologised that I had the formula wrong. But that doesn't change the fact that all the bullets energy comes from the gunpowder. Engery creates recoil, gunpowder creates energy.

[riflemanjim]

and what causes the powder to build pressure the resistance of a bullet on top of the powder period not bullet no pressure,more bullet more pressure no way around it read the chuckhawks page

[riflemanjim]

9mm in the lyman reloading manual is .355 the 357 is .357 wrong again.

[Southern661]

"9mm in the lyman reloading manual is .355 the 357 is .357 wrong again."

OH MY! So that MUST mean that static objects create energy!

[riflemanjim]

the point is your diameters like your point is wrong read what the experts say onRecoil is caused by two factors. The first is the bullet itself, which cannot be interfered with. The second is the expanding powder gasses again

[Plur307]

Don't you mean you are or you're :P Sorry just a pet peeve of mine just like people mixing up their, there, and they're. Speak English!!!!

[riflemanjim]

what else was said is that a muzle brake is more effective on a light bullet with a heavy powder charge cause what a muzzle brake is working on is the jet effect of the gases

[riflemanjim]

equal and opposite reaction that is physics 101 heavy bullet more recoil.and we are taslking about cartridges casure that what your basing your claim on dont c hange the parameters to fit your answer.

[Plur307]

Not true. The equation for energy when speed and velocity are known is: Energy=1/2(mass) x ((velocity)squared)

Taken straight from wikipedia.

"Note that the kinetic energy increases with the square of the speed. This means, for example, that an object traveling twice as fast will have four times as much kinetic energy."

It would take more energy to shoot 50 gr at 2000fps than 100 gr. at 1000 fps.

[Southern661]

@Plur307

Thank you for correcting me.

[Plur307]

No problem. I've always found that sort of thing interesting. It always seemed like a big slow bullet would have more energy but light fast ones seem to have more energy according tot he physics.

I think that was why the 5.56mm round was invented in the first place.

[Southern661]

@Plur307

Well depending on how much powder is behind that big slow bullet depends on how much energy it has. It takes far more energy to get a .45 moving at 9mm speeds. Their has been great sucess with +P 165 grain .45 ACP loads. They travel at around 1200 FPS and are fully lethal twice over. What bullets need is a good speed to weight ratio.

55 Gr x 3,300 FPS = bad

75 Gr x 2800 FPS = Good

[Plur307]

Well of course a big bullet going fast is even better :) Take the .50 bmg for example. It's a massive bullet with a high velocity.

I think energy transfer is also important. It's pointless to have a bullet that will just blow through a target and not transfer energy. I think the .45 excels at energy transfer.

[Southern661]

@Plur307

The .44 magnum is big, fast and heavy. Even with hollowpoints its sure to clear your thoratic cavity without a thought to stop, but just because it over penetrated doesn't mean that it isn't potent. The .44MAG still makes a very large wound cavity and a respectively large entry wound, which gives you two holes to bleed from. Now, a .45 hollowpoint might not have over penetrated, dumping all its energy into the target, but that doesn't mean it dumped more energy than the 44. Right?

[Plur307]

I was watching myth busters a few weeks ago and was amazed that a 9mm out of a handgun went like 6 feet in ballistics gel while a .300 cal out of an M1 Garand went like 1.5 feet. However, the .300 cal obliterated the gel and left a cavity the size of a melon. The 9mm just left a hole.

Terminal ballistics are a whole different story than energy alone. Each bullet seems to have its upsides and downsides. I've always liked magnums (.357 and .44).

[riflemanjim]

you cant beat velocity when it comes to total destruction of an object a bullet that dumps all its enegy inside a target is far more effective.

[Southern661]

@Plur307

I believe the M16 (5.56) was developed as an Air Force survival rifle. The Air Force bought this new rifle without permission from the Army, and the Army got all pissed off about it. The Army adopted the rifle to keep up with modern technology, and then issued it without cleaning kits and filthy ball ammo, to spite the Air Forces decision.

[Plur307]

Wasn't Stoner an aircraft engineer?  Makes sense to me.

[riflemanjim]

your wrong the m16 was developed as a replacement for the heavy m14 as well the abilty to carry more rounds they had most engagements occured at under 200 yards a 308/30-06 is way overkill on humans at that range plus the larger rounds were harder to control under full auto.

[Southern661]

@riflemanjim

"your wrong the m16 was developed as a replacement for the heavy m14 as well the abilty to carry more rounds they had most engagements" If thats true than why did the Air Force adopt the M16 first?

What was origionally said is the weight of the bullet doesn't create recoil, the charge behind it does. The gunpowder creates the energy which is felt recoil and momentum behind the bullet. I was using the 50-2000 100-1000 as an example, bullet weight does not create recoil.

[riflemanjim]

Flat out the army brass didnt want a new plastic gun they wanted the old large caliber. old school mindset.

[Southern661]

The only source of energy within a catridge is;

A)The bullet.

B)The gunpowder.

C)The brass.

D)rifemanjims thick skull.

[riflemanjim]

the only thick skull is a person thats been given a site by a muzzle brake company that says bullet weight affects recoil simple as that i believe thats the second sentence on the page

[riflemanjim]

thats exactly whast told you before

[Southern661]

@riflemanjim

I was wrong about the formula for the energy, but I was right about the fact that without gunpowder theirs no recoil.

9mm - .357MAG, both shoot (example) 125 grains and are almost the same diameter but the .357 has more POWDER not weight.

As far as the "higher pressure more effective muzzle break" youre now pulling- I said this; Muzzle breaks take the pressure and use it to combat muzzle rise. The more pressure the round has, that pressure is combating the muzzle rise

[riflemanjim]

YOUR argument is wrong get it through your head. If you seat a 100 gr bullet on top of 70 grains of powder,then you seat a 200 gr on 70 grains all things being equal you dont double or half the recoil, ie the difference is the bullet weight period.Remeber heavier out the front means more it pushes back period thats why I used the 300 cause you can get exactly double the bullet weight per given powder charge. Any muzzle brake company will tell you 7mm brake is more effective than one on a 458.

[riflemanjim]

And what that means is that a bullet with less mass has less recoil,ie heavy bullets recoil more.hmm lets see whats that called oh yeah equal and opposite reactions.

[daniel9214]

sure like to see that low light test.

[weaponeer]

Do you make one to fit the HK91/G3?

[clap5]

I just ordered the PWS FSC-47 muzzle brake for my AK-47. Only $94 and it looks to work just as good as this.

[walter00556]

I'm in the market for a brake or flash suppressor and would really like to see a video of one of these

[Southern661]

Clap5,

Is the 7.62x39mm comparable to 5.56 when it has the muzzle break installed?

[clap5]

7.62 still has a harder recoil. Slightly less accurate with a break installed...But it depends on what style of break you use. Are compairing standard AR breaks with AK 47 slanted breaks? Or My break vs AR with no brake?

[Southern661]

Your AK with a muzzle break vs 5.56 with no muzzle break.

[m249a1]

do you make the one in the video for an sks?

[surefirebeam]

The barrel is threaded the same as an AK-47, but you would have to remove the front sight assembly in order to attach a muzzle break to the gun.

[ROBUSTO76]

What's the muzzle flash like during low light operations?  Not really complete darkness, but more from an LEO/first responder standpoint. Is the flash blinding? Any available videos?

[surefirebeam]

The muzzle flash is greatly reduced in low light conditions and no, it's not blinding at all. I've seen some tests but none are available to post.

[surefirebeam]

We have not built a commercially available suppressor adaptor for the AK47.

[clap5]

Do that make one for the AK 47 7.62? Which model is this particular muzzle brake?

[PainTrane01]

sweet video.

[ejbock]

Impressive! Are these available for 7.62 AKs?

[XXNERVEXX]

lmao it wont help the accuracy of that gun

[ddmo2]

nothing will lol

[whaib87]

OK, for the armchair rambos out there, please don't speak about the accuracy of the 7.62 AK without mentioning that you're talking about your personal experience and which AK it was. Because you won't hear much of that from people who actually own a GOOD 7.62 AK. As for FULL-AUTO fire, you might want to browse further here on you-tube because there are videos showing PHENOMENAL results with good compensator/brake kits.

[Despierto]

What is the difference between the long MB and the short one? Just the type of suppressor they can be attached to or is the 2" model more efficient?

[truckcop1]

Longer one allows the suppressor to overlap the barrel, minimizing the extra length added to the barrel. Shorter one allows end-attachment to shorter barrels. Different model suppressors go with each different MB.
