Magpul Pmag M3 Window 7.62 20rd Mct

The Magpul Pmag M3 Window 7.62 20rd Mct is a purpose-built 20-round magazine engineered for precision rifle platforms chambered in 7.62×51 NATO (.308 Winchester), including SR25 and M110 pattern systems. This magazine addresses the operational reality that shooters demand reliable ammunition storage in a lightweight, cost-effective package without sacrificing dependability in the field. Law enforcement marksmen, military designated riflemen, and civilian precision shooters rely on this platform for consistent performance across training, competition, and tactical deployments.

Constructed from Magpul's next-generation impact and crush-resistant polymer, the Pmag M3 Window delivers the durability required in high-stress environments while maintaining minimal weight at 0.38 lbs per magazine. The dual-side transparent witness windows enable rapid visual confirmation of ammunition count without removing the magazine from the rifle or pouch, a critical feature when managing multiple loadouts or conducting tactical reloads under time pressure. Advanced feed lips and witness round positioning ensure reliable chambering even after extended storage or rough handling, while the proven M3 geometry maintains compatibility with existing shooter muscle memory and existing magazine pouches.

This magazine is ideal for SR25 and M110-pattern rifle owners seeking a balance between capacity and maneuverability—20 rounds provides optimal weight distribution without the bulk of higher-capacity alternatives. The polymer construction reduces the corrosion concerns associated with steel magazines in harsh environments, while the transparent design accommodates both right and left-handed shooters. Whether stocked for duty use, long-range precision shooting, or designated marksman applications, the Magpul Pmag M3 Window integrates seamlessly into any 7.62 NATO platform that accepts standard SR25/M110 magazines.
