The Magpul PMAG 40 AR/M4 GEN M3 is a 40-round magazine for AR-15/M4 platforms that adds 10 extra rounds over a standard 30-round PMAG without compromising Magpul's proven feeding reliability. Built with next-generation crush-resistant polymer, constant-curve internal geometry, a self-lubricating anti-tilt follower, and a long-life stainless steel spring, it delivers smooth, consistent feeding in demanding conditions. Reinforced feed lips and an over-insertion stop support dependable function across M4, M16, AR-15, HK 416/MR556, M27 IAR, and other compatible platforms. Aggressive texturing, paint-pen identification panels, and a removable flared floorplate make it easy to handle, identify, and service. Made in the USA.
