Magpul PMAG LR/SR Gen M3 Window 308 Winchester 20-Round Magazine Coyote Tan

The Magpul PMAG LR/SR Gen M3 Window is a 20-round polymer rifle magazine chambered for 308 Winchester (7.62x51mm NATO). It is designed for SR-25, M110, Ruger Precision Rifle, and AR-10 pattern rifles in that caliber. The translucent window lets the shooter check remaining rounds at a glance.

The magazine uses a constant-curve internal body and an anti-tilt follower to feed reliably. It is an impact- and crush-resistant polymer construction, and it weighs substantially less than standard steel military magazines. The body is Coyote Tan. Optimized for cartridges with an overall length under 2.830 inches.

Not compatible with rifles that use M14, FN FAL, or HK 91/G3 pattern magazines, including the Armalite AR-10B, Springfield Armory M1A, and FN SCAR 17S. Magazines made after November 1, 2023 ship without the impact/dust cover, which is sold separately.
