anybody else have the chrome lining in the bore starting to chip? i have 350 rounds down the pipe and when i was cleaning the bore out today i noticed the chrome is flaking for the first half of the bore (closest the the chamber) but the second half is almost intact, there are some chips in it but not nearly as much as the first half.
also, can anyone else unscrew the barrel from the barrel extension (that chrome part that goes i9nto the receiver that the bolt locks into)? while cleaning i realized i can unthread it by hand no problem, it made cleaning a while lot easier though and there is a witness mark in both the extension and barrel so i was able to line it back up perfectly, just wondering if anyone elses is like that
