This is a Stainless Steel 10-round magazine for 9mm Colt-style rifles.
Improving on the classic Colt-style AR magazine, ASC’s stainless steel mags are some of the most durable, most reliable, and longest-lasting on the market today. Manufactured 100% in the U.S.A. from 410 Stainless .052 gauge, these magazines can stand up to the toughest use conditions without issue. From the first round to the last … expect nothing less than perfection from 9mm ASC magazines.
These compact, 10-round magazines feature chrome silicon springs and anti-tilt followers for ultra-reliable feeding. All ASC stainless magazines are heat-treated to enhance durability, then chemically-treated for corrosion resistance (ref QQ-P-35). Finished with ASC’s special Marlube, which wears into the magazine for maximum handling and functionality.
