Magpul Industries PMAG GEN M3 Window 20rd .308/7.62x51 NATO AR-10/M110/SR25 Black

The Magpul PMAG 20 LR/SR GEN M3 Window is a 20-round polymer magazine purpose-built for AR-10, M110, and SR25-pattern rifles chambered in 308 Winchester / 7.62x51mm NATO. The windowed design adds dual-side transparent windows so you can verify round count at a glance without removing the mag from the rifle.

The next-generation GEN M3 body is molded from impact- and crush-resistant black polymer for hard-use reliability. At roughly 6.5 inches long and about 5.8 ounces, this 20-round magazine drops into any standard AR-10/M110/SR25-pattern magazine well.

Made in the USA by Magpul Industries, the PMAG 20 LR/SR GEN M3 Window ships as a single 20-round magazine in black.
