Magpul PMAG 20/5 LR/SR Gen M3 7.62x51 Magazine #MAG291-BLK

This is the 5 round variant of the Magpul 20 round 7.62x51 magazine.

The PMAG 20 LR/SR GEN M3 brings many of the M3 improvements to the 20-round 7.62 NATO/.308 Winchester SR-25 magazine form factor and replaces the previous generation MAG243 in our line.

The 7.62x51 NATO (.308 Winchester) PMAG 20/5 LR/SR GEN M3 is a lightweight, cost effective, high reliability magazine for SR25/M110 pattern rifles, constant-curve body, anti-tilt follower, and snap on Impact/Dust Cover. Designed specifically for military-issue MK11/M110 rifles and mil-spec ammunition, the PMAG 20LR/SR is less than half the weight of standard issue steel magazines and maintains a service life round count approximately equal to the rifle barrel itself.
