I just finished a kit yesterday that had a assembled AR10 Aero upper(fluted 308 barrel/handguard/brake), with complete lower parts kit and a ADK BCG. I had a stripped PSA AR10 Gen 2 lower that I put together and have the following issues: -bolt won't lock back -light dents in primer when firing I have found that once I chamber a round, the bolt does not close all the way, so I can push if forward and the gun will fire/eject fine. But does this every time. From what research I have been able to do, I think that the issue is with the magazine catch lever and of course they are on back order at PSA. Has anyone come across this before or have any ideas on how to correct this issue? I really don't want to buy a Aero lower then a PSA upper and end up with 2 AR10's.
