This is a Stainless Steel 20-round magazine for SR-25/DPMS LR -style AR-10 rifles in 6.5 Creedmoor
Feed your hungry battle rifle with the most reliable, most durable magazine on the market today—ASC’s stainless steel. Available in a variety of capacities and finishes, Duramag magazines are 100% made in the U.S.A. from the finest components and materials … making them the perfect upgrade for your AR-10 rifle.
These 20-round AR-10 magazines are crafted from 410 stainless alloy then heat-treated for maximum strength and durability. Then they’re chemically treated for corrosion resistance (ref QQ-P-35) and finished with ASC’s proprietary Marlube, which gradually wears into the surface of the magazine for improved handling.

Follower says 308 right on it and I just happened to have ordered a 308 magazine also at the same time. Both magazines were the exact same only the 6.5 creedmore mag was $10 more. I have been had... I knew when ordering there’s not really such a thing as a 6.5cm mag, I’ve always used 308 mags but curiosity got the best of me and they made $10 more off it.
