great quality

by -

I bought the magazine and loved them, I have bought a lot of things from primary arms and have enjoyed everything that I have bought, I thank you for the quality of your product and I will be buying more products from primary arms when I can, again thank you your speedy delivery and quality of your products.

Does not play nice with non CMMG Uppers

by -

If you run a CMMG upper, this should work well. However, if you run anything else, stick with an Endomag insert in a P-mag.

Best 9 mag

by -

I like how it fits and looks natural unlike the ones that takes a Glock mag. I would recommend anyone to buy this AR 9 magazine.

9mm modified ar-15 mag

excellent product. Makes it much easier to switch calibers on AR-15 lower. thanks

The ONLY mag conversion for the 9 mm Banshee

by -

I bought the CMMG Banshee because the Radial Delayed Blowback is the softest recoiling, most reliably ejecting PCC on a standard AR lower. Using the commonplace M2-PMAGS, CMMG created a simple insert that replaces the spring and follower, allowing it to VERY reliably feed ball, HP, and flat-nose ammunition through the Banshee. Gone are the aftermarket mag-well conversion pieces. Also, if you're all ready using a 5.56/.300 BLK, you wont need to change your AR magazine carriers.
If you're considering a 9 mm PCC upper to put on your standard AR lower, this system is THE BEST.
