The Magpul PMAG 30 AR/M4 GEN M3 in Coyote Tan is a 30-round 5.56x45mm magazine for AR15 and M4-pattern rifles (brand part no. MAG557-MCT). Magpul builds the GEN M3 from crush-resistant polymer with an anti-tilt, self-lubricating follower and constant-curve internal geometry for smooth feeding. Reinforced feed lips and an over-insertion stop on the spine help it run in M4, M16, AR15 and HK416 type rifles. A paint-pen dot matrix lets you mark loads, and a slim, flared floorplate makes it easy to pull from a pouch. It is a go-to magazine for range, duty and home defense.
