Magpul Industries PMAG GEN M3 20rd 7.62x51mm/.308 OD Green Magazine

The Magpul PMAG GEN M3 is a 20-round polymer rifle magazine purpose-built for SR-25, AR-10, and M110 pattern rifles chambered in 7.62x51mm NATO / .308 Winchester. Part of Magpul's proven third-generation GEN M3 family, this LR/SR magazine delivers reliable feeding, durable construction, and broad platform compatibility.

Constructed from a crush-resistant polymer with a long-life stainless steel spring and an anti-tilt, self-lubricating follower, the PMAG GEN M3 is engineered for consistent performance. The constant-curve geometry, optimized for SAAMI-spec ammunition, supports smooth feeding across a wide range of loads. A textured gripping surface and side-fluting aid in extraction, while the OD Green finish provides a low-visibility option for tactical and field applications.

Designed and made in the USA, the PMAG 20 LR/SR GEN M3 is a lightweight, cost-effective upgrade or replacement magazine for precision and duty rifles in 7.62x51mm NATO. This listing is for a single 20-round magazine.
