Dane Armory Posted February 24, 2016 Report Posted February 24, 2016 There was a thread in here where someone was arguing that his LWRC M6A2 was God's gift to the AR platform. Someone else posted an article written by a guy who runs one of those Vegas gun ranges with all the cool rental toys. I'm pretty sure that place is harder on guns than even military service, and his experience was the piston guns can't hang with that type of abuse. I don't feel like digging it up but maybe someone else can post it.The Gun Store !I went there , had to shoot my third choice .Tommy gun broken, Sturmgewerh 44 broken spring.. There stuff gets abused !
Frankh252 Posted February 24, 2016 Author Report Posted February 24, 2016 It appears the consensus is that DI is more than adequate. I plan to stick with DI, just looking for the input of others who are more experienced than I. I learn a lot from written info but nothing compares to experience.
planeflyer21 Posted February 24, 2016 Report Posted February 24, 2016 I used to be in the "pistons are more reliable" camp, primarily from listening to older Garand/M14 guys.Then, after looking at the evidence, that seems to be a myth that doesn't bear out in reality. A quality build is a quality build and DI has less moving shite to cause issues.
unforgiven Posted February 25, 2016 Report Posted February 25, 2016 A clean rifle is a happy rifle.Just sayin.
Frankh252 Posted February 25, 2016 Author Report Posted February 25, 2016 Cleaned, cleaned again and well lubed in between 's. Personally, I like Stoner's DI and think of AK's as the other kind but respect their impact & influence.

If I remember correctly the M1 Carbine's piston system was designed in a US prison in the late 1920's and later pattened. It was one of the first PDW guns.

bubbas4570 Posted March 16, 2016 Report Posted March 16, 2016 https://m.youtube.com/watch?v=CfZcEjdvx8c In case anyone hasn't seen these, here is a link to Iraqveteran1888's latest video of his meltdown series. This last on he does a piston AR, the one before is a DI AR, and the first is done with an AK. Full auto until failure....almost sounds like an old Bestie Boys song title.
Spartacus Posted July 12, 2016 Report Posted July 12, 2016 This has absolutely nothing to do with a fad, or meaningless cult following, with no basis in mechanical superiority. The direct gas impingement system is, and always has been, the Achilles Heel of the AR platform. Carbon fouling causes jams. With cheap ammo, and cheap powder, this happens rapidly. Sometimes, even within 100 rounds. This is why you NEVER get carbon fouling issues and stovepipe jams in AK variants, as they utilize indirect gas impingement systems. I have a Armalite AR180B (5.56) that has twin impingement rods and it has never jammed, no matter how many rounds i run through it, in succession. The gas piston conversion is exactly what the AR platform has needed, since it's introduction. Ever wondered why there's no need for a forward assist, on an AK? Now you know. The last thing you want to do, is blow a bunch of dirt and garbage into a tight-tolerance system of lubricated, moving parts. It's like running the exhaust, from your car's engine, back through the cylinders. Wouldn't take long for that thing to seize up and quit running. That's what happens with direct gas systems. Gas and carbon should be expelled outside the system, where they belong. So, everyone can have their opinion, but if you're betting your life on the reliability of your weapon to function flawlessly, when it counts....then get rid of your direct gas system and upgrade to
survivalshop Posted July 12, 2016 Report Posted July 12, 2016 (edited) Man Spartacus , your first post & its full of a lot of misinformation in it . Did you even watch those videos ? The Piston system & the DI system AR's ran the same amount of ammo to fail , not to mention the DI rifle used a lighter Barrel then the Piston system . The Fuking AK was custom built & only went a total of 95 rounds more then the AR's , not a true comparison to an off the shelf AK . I like those videos , not something I would do with any select fire weapon I owned . For your information , I was a Class III FFl for a whole bunch of years & got to build & fire a host of weapons , most here would give there right nut to have . Edited July 12, 2016 by survivalshop
MikedaddyH Posted July 12, 2016 Report Posted July 12, 2016 DI systems work good enough ! This one time at a AZ shoot we dumped around 500 rounds in under 45 minutes through a bumpfire AR . We had to switch uppers. Rounds would cook off in the chamber. My upper was glowing and steaming. Great stuff !
