Took my carbine to the range this weekend. Everything seemed to be functioning fine up until I was getting ready to pack it in. On my last magazine the BCG didn't seam to be cycling fully to strip the next round. I would cycle the action, chamber a round and end up with a single shot. I inspected the rounds in the mag, Lake City 55gr, M193; no issues there that I could see so I packed up the rifle until I could get home and give it a proper look-see.
Upon disassembly I could see that the carrier key was visibly and physically loose, even with what appeared to be adequate staking. It appears to me that I was bleeding way too much gas, causing the cycling issue.
Here is my question, should I remove and re-torque the existing key and re-stake or should I replace the key and screws and then re-torque and re-stake. What say you guys?
