Magpul PMAG 25 M118 LR/SR GEN M3 .308/7.62 NATO Window Magazine

Magpul builds the PMAG 25 M118 LR/SR GEN M3 (part no. MAG577-BLK) as a lightweight, made-in-the-USA magazine for SR25/M110-pattern rifles, chambered in .308 Winchester/7.62x51mm NATO. Unlike a standard SAAMI-spec magazine, the M118 variant is sized for longer match ammunition up to 2.830 inches overall length, while still holding a true 25-round capacity. It shares the constant-curve body, anti-tilt follower, and transparent MagLevel window of the standard PMAG line, molded in black polymer. For Magpul Industries owners running long-for-caliber match loads, this AR magazine is built to feed them reliably.
