Piston ARs: How Much Cleaner and Cooler are they? Live Fire Test 2/2

[toob247]

i just wanna say I love the U.S. , you know before youtube we would have to go rent one of whatever we wished to know of , to find out all this info in all of these gun vids . Thanks to ALL of those that perform this kind of service.

In the case of these rifles I still think I need one of each for some reason:)

[the308capital]

@toob247 America is great when it comes to firearms for sure.

[Sashalexandros]

how many mallfunctions had this ruger ion your practice, i just want to buy something on ar platform?

[the308capital]

@Sashalexandros I never had any malfunctions with either rifle in this video.

[Sashalexandros]

@the308capital i muslty heard about mallfunction with pmags on M4/AR15 and i just wanted to know if this can be reffered on ruger also

[mandojb]

Great Video !!!!



[the308capital]

@mandojb Thanks.

[UrbanArmed]

Great video bro. This was really comprehensive and helping me in my decision making..

[the308capital]

@UrbanArmed Thanks, Glad it was useful.

[tbilisicentralv2]

@545Krinkify naaah...Ak74 is a better choice

[highsierra67]

Nice! I have operated Bushmaster, Sig 556 and now have a POF. I thought there would be a greater variance between the two, actually... Thank you for a complete and comprehensive test of Gas inpingement and piston... Great job!

[the308capital]

@highsierra67 Thanks. I like the Sig 552 over the 556 personally. POFs are nice rifles.

[reeseman67]

What about the carbon buildup/HEAT buildup in the gas block of SR-556? Thing was a HEAT SINK on the G.Block of SR-556, took a little skin off!! Theyre both great, but the new Nickel Boron coatings make's the BCG on D.I. guns cleaning MUCH EASIER, and don't need lube to run it, IT'S PERMA-LUBED!! But really liked this vid, I also thought the bbl of the SR-556 would have been warmer, or at least in MY shooting of it it seemed MUCH hotter under rapid fire (vs DSC STAR-15, HBAR). KEEP IT UP!!

[the308capital]

@reeseman67 That Nickel plating is great for DI BCG. A lot of carbon does build up in the piston block for sure, I just didn't feel like taking it apart. I can't nor wont say one system is better than the other. However, I can say that both rifles function as asked. Thanks for watching.

[kuglebugle]

Thank you for taking the time and money to do this. Well done video.

[the308capital]

@kuglebugle No problem, conducting the test was fun.

[the308capital]

@lHustonProductionsl Thanks. The Wolf gave me no problems. I wouldn't recommend using it all the time but for this test it was perfect. Tula ammo is utter dogshit, so stay away from that stuff. DI ARs work just fine but the concept of a Piston AR is accepted. It is for each gun owner to choose which they like because they both seem to work when asked.

[blitzen762]

outstanding report ... i like the Rock River better for some reason and want the LAR 8 carbine for Christmas ......... if i friggin win the lottery. Peace :]

[the308capital]

@blitzen762 Thanks

[hobosapien081]

great video, I really thought the piston was going to have a way warmer barrel, great to know from your test that it's not the case :)

[the308capital]

@hobosapien081 Thanks for watching.

[Simmstar]

Great test I love RRA

[the308capital]

@Simmstar Rock River is my favorite AR builder too.

[to0nice4eva]

U guys need to add stag model 8 to the group

[the308capital]

I don't need another AR, nothing against Stag.

[223JMH]

Which gun is higher quality; the Rock River Arms or the Ruger?

[the308capital]

@223JMH They are both good ARs but I can't put them in the same group because the actions operate completely different. I would put both the Rock and Ruger at the top of the Middle Class of their respective group of ARs. Top class would be the more custom ARs like LWRC, Les Baer, POF, etc. If I could have only 1 however, then the Rock wins because it is lighter and the DI system is much more proven. Remember, piston ARs are still relatively new.

[HovaYourHero]

Nice video. Great information for those of us new to AR-15's.

[the308capital]

@HovaYourHero Thanks.

[Skragg101]

I think the EOTech made all the difference.. They have a very fine print section in the manual that states that it can make your gun run 40 - 50 degrees cooler!

Great vid man.. keep em coming!

[the308capital]

@Skragg101 It had to be that heat absorbing EOTech, LOL. I knew there was a reason why they're better than an Aimpoint!

[jetfuel545]

Great part 2. That was definitely rapid fire to heat them up quick. I did not know what to expect from the RR bolt/carrier, I kind of though it might be hotter judging from how hot the barrels got in front of the sight post. I bet that barrel was quite a bit hotter near the chamber. I dont think that temp of the RR bolt was ever going to case a malfunction and I generally do not see a time where I would rapid more than that. great test, thanks again.

[the308capital]

@jetfuel545 Thanks. That test was as fair as I could make it given the environment and tools I had to work with. The biggest bitch was trying to fit the firing and bolt rag swipes all in one cut so nobody could claim I cut the camera, cleaned the piston bolt and re spliced the vid. I crammed it in as best I could. One 15 minute vid would have been desirable but 18 minutes and 2 parts was the best editing I could do.

[esh325]

Great test! Very fair. I thought the barrel was going to be warmer on the DI rifle because of the gas tube, but I was wrong.

[the308capital]

@esh325 Thanks. Yeah, that surprise me too with the DI not being hotter. I do like the DI ARs better. They have 50 years of service backing them up, plus they are lighter. Rock River's PDS carbine is probably the better design for piston AR styled rifles because it is a monolithic bolt and recoil rod which eliminates the need for a buffer tube and "tilt" problems thus associated with it.

[esh325]

@the308capital Yeah, the DI AR's are much more proven. Some people just say to get a rifle that was designed as a piston from the start if you want a piston AR. They might be right. There sadly aren't really much choices for a 5.56x45 "assault rifle" besides the AR15 though.

[the308capital]

@esh325 I like the HK 416 but wasn't willing to pay $2,700 for one. For that price I'd get the SCAR L. Check out the Rock River PDS. It is more like the SCAR than any other piston AR and $1000 less. Without the buffer tube they were able to give it a side folding stock. It's a neat concept but it is also too "new" to have any reasonable reliability tests conducted. Like you stated, every piston AR is completely different because of the each others' patent design infringement.

[esh325]

@the308capital Me neither. I looked at the website, the Rock river PDS is certainly a very interesting. Not many folding stock AR's out there. I think if I'm going get another tactical 5.56 rifle, it will be a SLR-106, just because I have a hard on for AK's.

[the308capital]

@esh325 There's nothing wrong with an AK, go with what works.

[friskyrabbit]

As for civilian use I don't think the difference between the two systems adds up to a hill of beans but the horror stories of the failures of DI guns don't come from the civilian market, they come from military front line combat troops operating in harsh environments putting thousands of rounds through their weapon a week. The DI CAN run reliable but under those conditions it just requires more babying than a piston system would.

[esh325]

@friskyrabbit Yeah, I don't really think civilians will ever see the difference reliability. Perhaps a soldier would like you said. I remember reading about the battle of Wanat where their guns overheated. The Marines recently adopted the M27 IAR (basically a HK416) so a piston must have some type of advantage. There are also armies around the world that have experince with the M16 and M4, but have added HK416's to their inventories.

[friskyrabbit]

@esh325 Completely agree civilians will probably never see a difference. Just comes down to preference although if you go with a gas piston system you will have to address possible carrier tilt issues. There are after market devices like extended lip buffer tubes and a nippled buffer made by FRS that can negate carrier tilt. But it is very telling that special operation military units who have a choice in their equipment are starting to use gas piston AR variants like the HK.

[esh325]

@friskyrabbit The gas piston AR does have a lot of problems. Plus there is no standard gas piston design. Everybody is different. If you got carrier tilt, then it's a poorly designed piston in my opinion. The HK416 is the most proven piston design in my opinion as it's been adopted by armies around the world. It's expensive though.
