Magpul PMAG 20 LR/SR Gen M3 7.62×51 Nato 20 Round Magazine

The PMAG 20 LR/SR GEN M3 Window is a lightweight, durable 20-round magazine built for SR25/M110-pattern rifles chambered in 7.62×51 NATO/.308 Win. Made from impact- and crush-resistant polymer, it features dual side windows with the MagLevel system, allowing quick visual round checks using a high-visibility indicator coil and numbered markers. A stainless steel spring, self-lubricating anti-tilt follower, and constant-curve internal geometry ensure smooth, reliable feeding. Its textured surfaces provide a secure grip, while the slim flared floorplate improves handling, protects against drops, and fits easily into tight pouches. The magazine is easy to disassemble for cleaning, weighs less than half of a steel mag, and is designed for SAAMI-spec ammunition with a service life that rivals a rifle barrel. Its also compatible with existing 7.62×51 PMAG accessories and includes a paint-pen dot matrix for simple identification.
