I ordered qtty 2 CProducts 30 rounder mags from CDNN for my AR.
The follower is good.
The floor plate is good.
The spring is good.
The magazine body is crap. It's so thin that it deformed when I tried to load the magazine from strippers. I'd get 10 rounds in, then whack the heck out of it to align the rounds, then I'll try to get another 10 rounds in, whack the heck out of the mag.... Bottom line? NO WAY will I even take these magazines to the range.
I kept the followers, floor plates, and springs as replacement parts. The bodies got thrown away.
I'm staying away from CProducts. Pure crap, IMO.
