The Magpul PMAG 30 Gen M3 Window is a 30-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. NOTE: GEN M3 PMAGs may not be compatible with all billet lowers without slight modification of the magazine overtravel stop.
