K10M-10; 10 round 10mm AR-15 Magazine

10 round 10mm Magazine.

This is the new generation pistol caliber magazine for Olympic Arms carbines and conversion uppers chambered in 10mm. While the physical size of these magazines are identical to the standard capacity magazines, they are permanently blocked internally to prevent the magazine from taking more than 10 rounds.

Are these mags tough? You bet. Made in the USA (Washington State) using the latest technology of fiberglass embedded polymer, you can run these mags over with your car, and they keep on functioning!
