anyone ever seen this before?
installed as per instructions.
bent the key and the piston too.
the buffer tube seems bent upward too but functions.
buffer tube might be my imagination.
damn no i havent seems like your piston drove in to your carrier key and either the bolt was locked up in the chamber or your buffer tube did not allow the BCG to move. i'm going to say dirty chamber.
thats a no on the dirty chamber.
only ran about 250 rounds before it puked.
i think what happened was the key repeatedly battered the screw, pulling it up a bit and then all hell broke loose.
was hoping for some direct adams input.
i'll try calling them tomorrow.
i have heard good things about thier cs.
Looks like the screw backed out, then the piece was bent. Only way I see that happening.
How about some more pictures, of the other side, as well as top down view?

Had happened to me 3 times... Their Customer Services is pretty good though. They've fixed it each time. Guess they're looking deeper into it now that it's happened to me for the third time. I"ll let you know what they come up with.
Check the spacing between the gas block and the piston tube. It's supposed to have a gap between .015 and .025 wide and this has a direct effect on the speed and force at which the rod travels back. Outside of these parameters, bent rods can be the outcome. It might be something else but I'd check the spacing.... I'd also buy a 1 piece carrier, they are great. (though if the spacing is off, the carrier would have survived and you would just have a bent rod)
will do, thanks for the insight.
Just wanted to add, their CS is top notch AND I learned what I offered up as a place to start, from them.

just talked with adam's tech support on the phone.
i"m very impressed so far.
sending my carrier in for inspection/repair.
John spent 25 minutes talking with me about the problem and explaining the possible causes.
looks most likely to be the location/installation of the gas block.
