Magpul PMAG 20 AR-15 Gen M3 5.56 20rd Magazine

The PMAG 20 AR/M4 Gen M3 is the short 20 round version of Magpul's Gen M3 polymer magazine for 5.56 NATO and 223 Rem. The compact body sits lower under the rifle, which helps when you are shooting prone.

It is optimized for Colt spec AR-15/M4 rifles, and the Gen M3 dimensions also let it run in the HK 416, MR556A1, M27 IAR, FN SCAR 16/16S and SA80. You get the anti-tilt, self-lubricating follower, a USGI spec stainless steel spring, an over travel stop on the spine, aggressive grip texture, and a flared floorplate that comes apart without tools.
