Product Specifications


The 7.62x51 NATO (.308 Winchester) PMAG 20 LR/SR GEN M3 is a lightweight, cost effective, highly reliable magazine for SR25/M110 pattern rifles. Magpul’s PMAG features a 20-round, constant-curve body, anti-tilt follower, and snap on Impact/Dust Cover functionality to help shooters keep track of their rounds.

The PMAG 20 LR/SR was designed specifically for SAAMI-spec ammunition. It 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.

The 10/20 riveted PMAG has been modified by Ace’s Armory to permanently restrict the magazine capacity to ensure compliance with magazine capacity restricted states. The PMAG is new from Magpul Industries and will be shipped in its original wrapper. We have modified the original magazine with a rivet to stop the follower at a precise location, thus permanently limiting the capacity of the magazine to 10-rounds. Each magazine is inspected during our quality control process prior to shipping to ensure compliance with state regulations.
