For the first time, there’s an ultra-compact 10-round PMAG model, perfect for hunting and other applications where the lowest possible magazine profile is desired. Ideal when shooting off a backpack or using a bipod. Even better, the 10-round GEN M3 has all the durability, strength, and reliability enhancements of the rest of the GEN M3 line – including the anti-tilt follower and constant-curve radius of the body to aid in round-feeding. Mfg: Magpul SPECS: Impact/crush-resistant molded hard polymer. Compatible with AR-15/M4/M16, HK® 416, MR556A1, M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and other similar lowers. 5.56mm/.223 ammunition only.
