So to get straight to the point, and this was repeating itself. basically first 2 rounds would load in perfectly and eject no problemo, the moment the second round was shot and it was time to eject the spent round, the lever got extremely difficult to pull open for the round to eject. the first 50 round went by easy and it’s just when the gun got hot that this started happening. I’m thinking the issue is with the magazine but was curious if others experienced similar issues? Thinking of bringing it to the gunsmith to let him have a look, would love if anyone here could also give me some maintenance tips.
