Magpul PMAG Gen M3 Window 7.62×51 20rd Mag

Description

The PMAG Gen M3 Window brings clarity to your reload management with transparent windows on both sides, letting you glance down and know exactly where your round count stands. Designed for SR25 and M110 pattern rifles, this 20-rounder strikes the balance between capacity and handling without adding unnecessary bulk to your platform.

Transparent Windows for Tactical Awareness

Magpul's MagLevel system pairs those dual-side windows with a high-visibility painted indicator coil on the spring and numerical markers on the magazine body. You get fast, accurate round counts without compromising the durability or reliability of the magazine. No more guessing when you're in the field or running through a competition.

Built to Last Through Heavy Use

This Gen M3 is constructed from next-generation impact and crush-resistant polymer that shaves weight compared to steel magazines while protecting the internals from field abuse. The stainless steel, corrosion-resistant spring and anti-tilt, self-lubricating follower work together with constant-curve internal geometry to keep rounds feeding smoothly under any condition. Service life matches your rifle barrel, so this isn't a magazine you'll be replacing anytime soon.

Practical Design for Real-World Shooting

Low-profile ribs and aggressive front and rear texturing give you a positive grip for magazine changes whether you're wearing gloves or dealing with moisture. The flared floorplate aids extraction and handling while staying slim enough to work with tight double magazine pouches. Disassembly is straightforward for field cleaning, and there's a paint pen dot matrix on the bottom panel so you can quickly mark your loads and ammunition types.
