Magpul PMAG 10 AR-15/M4 GEN M3 5.56 NATO Magazine - Black

The PMAG 10 GEN M3 is a 10-round 5.56 NATO polymer magazine for AR-15/M4 compatible weapons. This magazine features a long-life USGI-SPEC stainless steel spring, four-way anti-tilt follower and constant curve internal geometry for reliable feeding. A redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons.
