I received new factory 30 round today from midwayusa. I noticed right off that the mag had a gap on the back side in the edge where the steel is folded around the mag and spot welded. My other factory 30 rnd has no gap at all. The new mag is very hard to load the follower hangs up when trying to push bullets into the mag. After finally getting it full when trying to unload it the follower hangs and tilts and does not push the bullets up properly or not at all. My other 30 rounder has never done this and always works perfectly like the factory 20 rnd mags I have. I'm sending it back to midway tomorrow and hopefully getting another one that works like it should. Has anyone else seen this with any factory mini 14 mags?
