I’ve got a Curtis vector, manners prs2, hawks hill bottom metal, ai mags...feed perfect until the second to last round then that second to last round feeding from left side misses when chambering almost every time. Any ideas?
IMHO, the AICS mags are even more temperamental. I’ve had to file and adjust the feed lips on each one of mine for different actions I use them in. But once that’s done, they’re as smooth as glass.
The couple AW mags I have, one required me to lightly stretch the follower spring and ensure it’s married to the follower correctly to get the last two or three to feed without issues.
