Magpul PMAG 20 AR-10 LR/SR Gen M3 Window 308 Win 20rd Magazine

The PMAG 20 LR/SR Gen M3 Window is a 20 round polymer magazine for SR25 and M110 pattern AR-10 rifles in 308 Win and 7.62x51 NATO. Dual side translucent windows work with a high visibility coil on the spring and numbered markers on the body, so you can estimate your round count at a glance. Magpul calls this the MagLevel system, and it does not cost the body any strength.

The body is the impact and crush resistant Gen M3 polymer used across the PMAG line, with an anti-tilt follower and stainless steel spring inside. The shorter 20 round body sits lower than a 25 for shooting prone or off a bipod.
