Magpul PMAG 40 AR/M4 Gen M3 5.56 Magazine - Black
The Magpul PMAG 40 GEN M3 is a 40-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. Slim, for better compatibility with tight magazine pouches, this easy to disassemble magazine features a flared floorplate, low profile ribs, and aggressively textured front and rear surfaces for positive control. A paint pen dot matrix on the bottom panel of the body allows easy marking for identification.

Great magazine, very well made and I even used with my .300 blackout rifle and had no issues. I’m currently using it with my MK18 and haven’t any malfunctions. Great mag overall. Thanks to Primary Arms for being one of the most modest gun websites (even throughout these time when people abuse prices) and haven’t been price gouging none of their products, even through these difficult times. Thanks Primary Arms.
