Before I found the FAQ (thanks Troy) I bought 4 western metals 30 rd. (stamped "colt ar-15" on the floor) Are they worth rebuilding? They seem heavier than the US mag crap and 3 of 4 seem to feed okay, but the 4th pops the last round out (as the second to last loads) and jams. Would adding a new spring and follower make these worth keeping?
Thanks,
Rusty
