Made in the USA the Magpul PMAG D-50 is a rugged lightweight and reliable polymer drum magazine designed for SR25/M110 pattern rifles. The Magpul PMAG D-50 shares its DNA with the legendary Magpul PMAG GEN M3 which includes next-generation impact and crush-resistant polymer construction and the ability to seat fully loaded on a closed bolt. Robust stainless-steel internals withstand corrosion and long-term storage while loaded with no loss of function spring fatigue or reliability concerns. An anti-glare translucent window on the rear of the drum makes for quick positive visual indication of remaining ammunition.
