Magpul PMAG GEN M3 AR-10 7.62NATO 20 Round Magazine (10 Pack)

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.

The 7.62×51 NATO (.308 Winchester) PMAG 20 LR/SR GEN M3 is a lightweight, cost effective, high reliability magazine for SR25/M110 pattern rifles featuring true 20-round capacity, constant-curve body, anti-tilt follower, and snap on Impact/Dust Cover. Designed specifically for military-issue MK11/M110 rifles and SAAMI-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.

This Ten Pack Magpul M3 7.62 20 Round Magazine is Made in U.S.A.

New to Mag Shack

Bought an AR10and needed mags. The Magpul mags I got are not special. They're everywhere. So why pay more than needed? I bought the ten pack and saved real dollars, not small change. Thanks Mag Shack. I'll be back.
