I never checked anything when i got the gun haha. The chamber was fine was just a bad case, the rest of the 2 boxes were fine. Guess i was just over nervous about having a case split (first time for me and was in a new gun so i was worried cause i knew nothing about the possible issues).
S'pose i should get a front lug put on? Its had about 60-70 rounds through it now, no issues yet.
Still havent tried to bag anything with it though.

The only other thing ive had a problem with was ejection, the cases tended to not want to come out at first, but now they eject fine (didnt change anything).
