Over the last 4-5 months I bought somewhere in the order of 20 CProducts 30rnd magazine replacement bodies. It took a long time to test fire them all and i just got around to returning 3 of them. Two because they gave failures to feed and one because a magpul Gen II follower wouldnt fit into the mag tube.
About 1 week later i got the replacements and noticed the box seemed kind of heavy before i even opened it. Upon opening i found they sent me 8 mag bodies to replace the 3 i returned. I picked the best 6 out of the box based on magwell fit and they ran perfect. no stoppages, no follower hang ups, all drop free when empty.
It appears based on my limited sample that the mags CProducts in making right now have outstanding QC and CProducts definately went above and beyond sending me 8 in exchange for 3 returns.
I have rebuilt all of my really old mags at this point. But eventually, when i need repair parts again I will definately consider Cproducts.
