Magazine Reliability

[ss355]

My "15" round mags won't hold 15 rounds without shortening the front leg of the follower. I tested this by removing the floorplate and holding the spring to provide some follower resistance while loading. At 15 rounds, the front leg of the follower extended perhaps a 1/16th of an inch below the bottom of the mag body. I shortened the front leg of three followers and can now cram in 15 rounds in those mags, but the spring is so tight at the 15th round that it's a bear to load that round. I'll probably just run all my 15 round mags with 14 rounds.

My 25 round mags take 25 rounds just fine. I might be able to squeeze in a 26th round, but it would be a really tight fit, and I'm happy with 25 rounds.

Interestingly, my 10 round 7.62x39 mag works splendidly with Grendel rounds.
