Magpul PMAG LR/SR Gen M3 308 Winchester 20-Round Magazine Black

The Magpul PMAG LR/SR Gen M3 is a 20-round polymer magazine for AR-10 pattern rifles chambered in 308 Winchester and 7.62x51mm NATO. It is built for SR-25, M110 and LR-308 style rifles and is intended for use with ammunition having an overall cartridge length under 2.830 inches.

The magazine uses a constant-curve internal geometry and an anti-tilt follower to support reliable feeding. Its polymer construction is described as impact and crush resistant, and the body is substantially lighter than standard steel military magazines. The finish is black.

The magazine is not compatible with rifles that use M14, FN FAL or HK 91/G3 pattern magazines, including the Armalite AR-10B, Springfield Armory M1A, FN SCAR 17S and HK417. Impact/dust covers are no longer included with magazines made after November 1, 2023 and are sold separately.
