Adam Arms piston kit failure

[CJ]

I just hate shooting a di with a can.

By the time your done shooting your face looks like a coal miner.

I've never really had much of an issue with an AR15 since I'm right handed. Blowback guns are awful though.

Piston is the way to go if its got a can for sure.

That's the reason I decided on it, if you think DI is dirty, just try it with a suppressor forcing twice the particulate back into your action.

ARs run cleaner and cooler with a piston system since it's not directing all the hot gasses and crap back into the action. Once the piston has moved a short distance the gasses are expelled through a vent in the piston tube.
This usually translates to a more reliable rifle too, but I guess CJ's gun proved otherwise with a pistol length gas system.
I'm curious if the manufacturer will blame this on improper assembly or some part other than the piston setup. I know CJ knows his shit so I believe him if he says it was put together right.

I certainly followed the directions the kit has. I made sure the gas block was aligned vertically over the gas port, I aligned the barrel nut and delta rings, inserted the stainless bushing, made sure the op rod did not contact the bolt when it was locked in battery, and used a feeler gauge to verify 0.020" of play at the plunger/block. The op rod moved freely without the spring. So, my only guess is it's either something not covered in the instructions, or some sort of problem with the kit.

I've kind of wondered the advantage of going to a piston system... I haven't had any issues with DI.

That's Eugene Stoner's way of payback for screwing with his design.

That's rough man. Hopefully they're receptive and helpful.

[soap]

I'd send it back in pieces to show em.

[YALE]

Ah, shit. Sorry man.

Ouch

I have a carbine length rod on mine; my cousin has two rifles with carbine lengths. The only issues either of us have had is I did not have my gas block aligned good and it would not cycle, but no damage. Got that corrected and neither of us have had any problems and all three guns have had a few thousand rounds through them at least. Adams Arms carbine and rifle gas systems have a ton of satisfied customers, but I did zero research on the pistol gas systems so I really can't offer you any good information other than I have used some of their products successfully.

I am interested to hear what they say after you talk to them as I had planned on using more of their products in the future. Please keep us updated with their quality of customer service; I had planned on buying one of their complete carbine length uppers in the future so I would love to hear some firsthand customer service experience.

I think it has to do with the pistol length rod. The longer rod might be long enough to deflect any side pressure that would otherwise bend.

It seems the overwhelming majority of people with problems have pistol length rods. At first I thought it was overpressured, but it was throwing brass to my right, not forward. I didn't feel any excessive recoil or anything out of the ordinary.

I was thinking you could just replace the gas key, but I expanded the pic and it looks like the carrier and key are one. If that's the case, sorry to hear that dude.
