Magpul PMAG D-50 .308 Win/7.62x51mm 50-Round Drum Magazine
It’s capable of using longer-than-SAAMI-spec match ammunition, up to 2.830 OAL, such as M118LR. Engineered to the same exacting standards as the famous Magpul PMAG and PMAG D-60 drum magazines, the D-50 continues the PMAG tradition of high-capacity performance and dependability.
It is compatible with older model Bushmaster .308 ORC, Remington R-25, and DPMS LR308 rifles, but not optimized for bolt lock functionality with newer models based on the DPMS GIi design. NOT compatible with Armalite AR-10B, Springfield Armory M1A, Rock River Arms LARS, FN SCAR 17S, PTR-91, HK417 or any other rifles that utilize M14, FN FAL, or HK 91 / G3 patterned magazines.
