to be fair, the ctr mags dont have a stellar reputation for feeding. Of my 3 mags one would do this maybe 2 or 3 times out of 100–it would fail to pick up the next round. Its an easy fix to bend the spring so the follower doesnt hang up, there are several youtube videos showing how to do it. Other than that theyre smooth, and that one mag is the only hiccup like that Ive had in several tikkas.
