I traded some night vision with the owner of CMMG several years ago and used their 9mm 32-round mags and ended up getting extras which I am pleased with. I use a Magpula loader. Shooting 9mm subsonic with a custom Colt 9mm integrally suppressed AR, these mags work. I do not recall what they were but think it was about $25 each, which is a pleasant surprise. I do not know present pricing or availability.

Been a long time since I've been shopping for Colt style 9mm AR15 mags. The last time, I just bought Colts. Now knowing Brownell's offers some with their name on them, I might pick a few up just because.

If in the end (no matter the name on it), if is not made by metalform you are wasting your money.

Metalform makes them for Colt. That's your Huckleberry.
