I tried 2 of these out today in my SIG 556 at ASR
one of the mags failed to feed the last round on 2 occasions---the other
one was perfect(in 150 rds). I have used nothing but Colt M16/AR mags that are
over 35 years old(in my SIG) and never had any failures of any kind. I also put a
Magpul stock on my SIG and it is a big improvement(much tighter). Pete
