Description
Description: Magpul PMAG LR / SR Gen M3 Window, 20 Round Magazine 7.62x51mm NATO. The PMAG 20 LR/SR GEN M3 Window is a lightweight, cost-effective 20-round magazine designed for SR25 and M110-pattern rifles chambered in 7.62×51 NATO (.308 Winchester). Built from impact- and crush-resistant polymer, it features dual-side transparent windows, a high-visibility indicator coil, and numerical markers for quick round estimation using the MagLevel system. A corrosion-resistant stainless steel spring, anti-tilt self-lubricating follower, and constant-curve internal geometry ensure reliable feeding. Aggressive texturing and low-profile ribs improve grip, while a paint-pen dot matrix on the bottom panel allows for easy identification.
Other standard features include a flared floorplate that aids in magazine extraction and handling. This design also enhances drop protection while remaining slim enough to maintain compatibility with tight double magazine pouches. The magazine is easy to disassemble, allowing for straightforward cleaning and maintenance when needed.
Designed specifically for SAAMI-spec ammunition, the PMAG 20 LR/SR GEN M3 Window weighs less than half as much as standard-issue steel magazines while offering a service life round count comparable to that of the rifle barrel. Accessories developed for the 7.62×51 NATO line of PMAGs are fully compatible with the PMAG 20 Window.
