The Magpul PMAG M3 M118 LR/SR 7.62×51 25-Round Magazine (brand part no. MAG577BLK) is a lightweight, high-reliability magazine built for SR25/M110-pattern rifles that run longer-than-SAAMI-spec match ammunition up to 2.830 inches overall length. Magpul engineers the M3 generation with a constant-curve body and an anti-tilt follower for consistent feeding, and a snap-on impact/dust cover keeps debris out when the magazine isn’t loaded in the rifle. Transparent MagLevel windows let shooters check their approximate round count at a glance without pulling the magazine. Among AR magazines, this PMAG favors SR25/M110-pattern rifle owners who want a purpose-built magazine for long-OAL match loads.
