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 SAAMI-spec ammunition, the PMAG 20 LR/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.
The Superlative Arms patented “Bleed Off”, direct impingement, gas block for the AR15 platform adjusts the gas flow by bleeding the gas out of the block instead of restricting the flow like conventional adjustable blocks. Results: The pressure used in the block is reduced only to the amount required to drive the bolt carrier.
