In my opinion that was probably the best video for 3 reasons. 1. Steel case ammo works fine with no issues, even under full auto. 2. As you said, now manufacturers can resolve any issues with products. 3. Simply awesome to watch a gas piston system run like a champ.

[@ilikeanime66]

So we had a DI AR fail just above 800 rounds, and we had a good AK 47 fail just above 800 rounds, and now we have a piston AR failing just after 800 rounds. Of course all 3 guns failed for different reasons, and the DI AR was the worse failure of the three, but at about the same time all three weapons would have been out of the fight. I guess in the end it doesn't matter all that much what you pick, as long as it's a decent rifle, your odds are pretty good . Great video as always.

Thank you for the awesome video, but also thank you for the "if you haven't gotten shot yet" portion. Most people who think about gunfights don't consider that if you are using a main battle rifle, and you have expended over 100 rounds, if you haven't been shot yet, youre doing extremely well.

[@stevenl.cranford5992]

Watching the AK, AR gas-impingement, AR piston meltdown test it was interesting that all three rifles seem to fail around the 8 minute mark and roughly similar round counts. You could make a career testing different components in each rifle to improve the results (i.e. the barrel mentioned in this video). Can't wait for the next video in this series.

Awesome video, well thought out and informative. I'd like to see an HBAR 20" barrel on a DI gun now.

[@JoeyFragnoli]

I agree, since it was the barrel and not the gas system that failed in the direct impingement video, I would like to see if a di gun could go longer with this barrel.

[@TheAnnoyingBoss]

Lmt makes these monolithic uppers and they have a 20 inch barrel for one of them. I don't think they're DI but it's still pretty sweet how you can get an lmt quality monolithic upper with a full length barrel that also isn't old-school m16a4. Eventhough I like those too because I can actually afford one and I cannot afford an lmt 😂😂😂 but maybe one day

[@Vahkii]

Huh, good to know.

[@kkhankhalil]

A very decent approach to know the meltdown point of a Fire Arm, but there is no ending to these episodes bec. when the barrier is broken, another comes in the way. Improving the fire arm will increase the amount of ammo absorption but it will "ultimately" fail on another point. In practical, such a catastrophic situation never comes, either a person dies or the fire arm. And you are the person imho, who has fired record rounds so far in a man's life. Great work.

[@richardkautz2947]

A gas piston AR with full auto ?! That's so badass ! 👍

[@Cowboy.underwater]

So if you ran a thick barrel on a Di you would probably get over 1000. On the old test, it wasn't the gas system that failed, it was the skinny barrel. It looks like it's time for a retest.

[@ballinvsxx]

Agree. Not an apples to apples test. Since di gun went to almost the same before barrel blew out then di is easily the winner here.

[@AllDayEveryDayNL]

I love how these videos are fun to watch and educational, Keep it up guys!

[@jaymeseaston8117]

Post script- an M16 magazine loaded with 18/20 weighs 11 ounces each. 40 mags = 760 rounds = 27 1/2 pounds, or 3.3 gallons of water. In terms of kit, 20 round magazines are shorter and straight making a more compact package, with less volume; also, a lower profile in prone position, or traveling in wait-a-minute brush. It's easier to put 3 20 round mags in your pocket (18+54=72) than two 28/30 (28+56=84). That's only 12 less It isn't just the total number available, but time spent into moving to the point of contact while maintaining situational awareness; if you drop a reload, it's better to get a new one off your person without taking eyes off the threat.

[@michaelolszta2571]

Interesting. So it looks like the DI and the Piston meltdown experiments went just about the same amount of rounds before the rifles couldn't fire any longer. So much for the superiority of the piston guns! I'll keep shooting my Colt M4 in its original DI configuration. Accuracy is better than a piston gun and as long as I have a small bottle of lube with me, I should be able to shoot as much as I want without any problems. Eric, your published experiments are outstanding! The proof is truly in the pudding, Sir, and you've served that pudding up for all to taste! Much appreciated!!!

[@TheSalient0ne]

Awesome video! My thoughts are that they should machine contacting surfaces of the piston rod / divot the contact point on the carrier - hence providing a guide for a repetitive contact area, while strengthening both metals. Thanks for another entertaining video!

[@LexCinnabon]

Very cool. The same test with an MR556 upper or a 416 upper would be fantastic!

[@accur81]

Cool vid, guys. It takes guts to run a gun at over 1,000 degrees and I'm glad that AR didn't turn into a grenade on you. I used to be a huge piston fan and now most of my ARs, except two, are DGI. My SR-556 has gone over 1,500 rounds without cleaning or jamming, but I broke down and gave it a thorough cleaning. I notice that DGI ARs can run into issues at 400-500 rounds or so without cleaning, depending on the components being used. Nickel-boron BCGs work well for me, and I'm a fan of stainless steel barrels.

[@zmasterb92]

I'd be interested to see how an upper from primary weapons systems would do in a test like this. Their piston is connected directly to the BCG so there would be no chance for it to strike it

[@SethWilcox82]

What about a DI upper with a heavy barrel?

[@mctourer5549]

This is why I will never run a short stroke piston setup. The whole system relies off smacking bolt back. Try this with a PWS or and ARAK, something that is actually a reliable piston setup. You'll probably get thousands through it before failure

+Daniel Jones that's a AK-47, he's talking about the AK-74, aka the little brother of the 47. Debatably more comparable to a ar than a 47.

[@StarCypher]

Daniel Jones The WASR was garbage... They did another meltdown with a VEPR AK and it lasted 900+ rounds. The AK-74 shoots the 5.45x39 round, which is basically Russia's version of the .223/5.56x45 NATO used in ARs. I think an AK-74 has the potential to last longer than the AKM and AR, while possibly giving the Glock's 1,200 rd count a challenge.

[@FlowBaka]

I feel like the bolt let out and started mushrooming and led the piston go to the path of least resistance.

[@montepr803]

THIS

[@NavyCuda]

+Nam Nguyen I believe you are absolutely correct. Either through heat soaking into the bolt, incorrect heat treating, or insufficient material, the material was soft enough to mushroom. As the bolt carrier started to mushroom there likely would have been more space between the bolt carrier and the piston, adding to the pistons momentum before striking the bolt carrier. Due to the small amount of material, the bolt carrier mushroomed towards the top, moving the divot upwards. The piston would be forced to the center of the divot by the impact, bending the piston rod. From a design standpoint this is a direct advantage to the internal short stroke piston of the DI system, which has the piston concentric to the boltcarrier. The force can only act on the bolt carrier in one direction.

[@flossordie2256]

+Nam Nguyen That is very smart, your probably right.

[@mastalee1776]

+NavySturmGewehr so, if the bolt where the piston was hitting the carrier, it could of gone on longer maybe

[@NavyCuda]

mastalee If the mushroomed burrs had been removed, yes the rifle probably would have continued to function for a while. I imagine that the piston is captured for the most part, so it would take the piston actually bending enough to bind up in its normal path. This probably wouldn't have happened, it's more likely it would continue to mushroom over the bolt carrier at an accelerated rate until the bolt carrier bound up again against the charging handle.

[@JJGuccione]

Eric says: "And they say, oh well, it's a piston AR you never have to clean it or anything like that. Yeah, they can go a little longer without being cleaned, sure they provide a little bit more reliable operation under adverse conditions. You'll get a little bit more longevity in terms of continued use in the field without maintenance but at the core, it's still the same gun." Let's make it simple - - A little longer without being cleaned (bullshit Eric, they can go a lot longer). - A little bit more reliable operation under adverse conditions. - A little bit more longevity in terms of continued use in the field without maintenance. Geezus…I'm sold. And, guess who owns a POF 416 Edge? I think your round count was 2,737? If my math is correct and it is, that's 3-times the round-count of a DI. I popped an ACOG TA01NSN on that POF 416. Is it heavier? Yes, but when all the CLP is gone and there's no gasoline and/or diesel fuel to siphon, you'll be sorry. There aren't any ultrasonic cleaners to dunk your BCG into out the field. Maybe you can rob or swap parts with Gas-Tube-Johnny to make your DI serviceable?

you guys should do a video about how much pressure/power is lost from behind the bullet when a portion of the gas goes through the gas system as opposed to if there was no redirection in the gas flow. maybe use an adjustable gas block to close off the system for a couple rounds, or compare it next to a bolt action of the same barrel length and caliber. you know.. for science or whatever.

Boy it seems like a piston AR is the way to go!

[@Targetpopper]

I'll stick to Stoner's DI design. Never was a fan of the piston gas system on the AR15.

I thought I was the only one

+Steve Wiswell Me too buddy,ill di anyday.

[@kurtkenehan8017]

can you do an m1a please

[@lewnance]

To compare apples to apples, you need to re-do the DI gun with a HBAR barrel since that was the failure point on the DI gun and not the gas system! PS: How about a "wall-of-tannerite" video?!

[@jlpowell8432]

Dude you should do a full auto with a Primary Weapon systems upper! Its piston is attached to bcg and moves near the gas block. Its gas block system is designed with maximum dwell time to reduce the harsh forces on the piston system. Would fire a tad slower but thats fine for me

[@keithodonnell5835]

I thought i was listening to darth vador soon as the failure happened with that heavy ass breathing !!!💯😂

Nixon is really out of shape

Ruger Mini 14 Next

[@warlock1005]

Eww

[@Prepare2Survive]

warlock What's wrong with the mini 14 ? It's a copy of a rifle that helped us win WWII.

[@warlock1005]

+Prepare2Survive For the price you could do a lot better

[@Prepare2Survive]

warlock Yeah, that's true unless you live in a state that banned AR15 and AK47 rifles and the only preban options cost almost $2000. Regardless the Ruger mini 14 is still a nice robust classic design.

[@warlock1005]

+Prepare2Survive It is a great design. Do you live in NY?

[@newbzor52]

Isn't it kind of apples to oranges comparing this to a DI gun with a lightweight barrel, since the barrel is what failed by bending. You should redo the DI with a heavy barrel..

[@andreharris9474]

Man I wish I had ur knowledge of weapons and military thanks for all cook off of my favorite AR15 all types.

[@Jet2416-Reloading]

First off I'd like to say that I enjoy watching all your videos, not just the meltdowns. I'm no expert by any means. I like shooting different guns for fun and have several for home defense. I'm really glad to see that the piston gun didn't overwhelm the performance of the DI. It has always been my opinion that for the added expense of the piston impingement system it is just not worth it for a semiautomatic rifle. As I see it, if the DI rifle you used for the meltdown video before would have had a comparable barrel to the piston gun in this video it may have easily outperformed the piston gun in number of rounds fired. With a heavy barrel I believe the DI rifle could have gone for a good bit longer before the gas tube finally failed.Thanks for the videos and all the information, guns, ammo, and accessories you show.
