I googled, and searched around briefly and found nothing that helps me any.
a while ago i bought a we scar off someone, it came with a few leaky mags.
recently i took them apart and resealed them, added new orings, etc.
and now they wont seat correctly. in the following pics the black mag shows how it fits snugly, the tan one sits too high, and the gas release port on the mag collides with the brass tube.
the last pic shows one of the mags that wont seat properly inserted. the bolt will travel but not smoothly.
any help would be greatly appreciated.
