The Magpul PMAG D-50 is a rugged, lightweight, and reliable 50-round polymer drum magazine designed for 7.62x51 NATO/.308 Winchester ammunition for SR25/M110 pattern rifles. 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. In addition, the D-50 brings GEN M3 features, which means enhanced strength, durability, and reliability.
