Magpul PMAG Gen M3 Window 7.62×51 20rd Black

The Magpul PMAG LR/SR Gen M3 Window is a 20‑round polymer magazine designed for SR25/M110 pattern rifles chambered in 7.62×51 NATO (.308 Winchester). Dual-side transparent windows and numerical markers provide a fast round-count estimation via Magpul’s MagLevel system. The magazine uses a stainless‑steel, corrosion‑resistant spring and an anti‑tilt, self‑lubricating follower to promote consistent feeding. Low-profile ribs, aggressive front and rear texturing, and a flared floorplate aid handling and extraction.
