Mag feed lips

Guys,

I haven’t thought about his in a while…so my brain isn’t quite working.

Because of a new class I’m taking May 1st, I’m breaking out the mags and trying to pick the ones I’ll use for the course. I’ve been using just my “range only” mags for months now.

Some of the mags I looked at last night had feed lips that were a bit spread out. I refurbished some of them from the ground up and still haven’t had a chance to test them…but that’s not my concern right now.

My question is, what malfunction occurs when the mag’s feel lips are spread? Double feeds?

Sorry, but I can’t remember.

Yes, and a good test in “Green Eyes, Black Rifles” is to load a 30 round mag with 20 rounds, and hold the mag with one hand and use your other hand to slap the bottom of the magazine a few times, very hard. If a round flies out of the top, it’s feed lips are too worn and you should destroy the mag
