Magpul’s New PMAG 20 LR/SR GEN M3 Magazine Has Round Count Verification Window

Magpul’s new PMAG 20 LR/SR GEN M3 Window magazine is a 20-round magazine with dual-side transparent windows for SR25/M110 pattern rifles chambered in 7.62x51 mm NATO (.308 Winchester).

Thanks to the windows, you can easily conduct a quick count of the approximate number of rounds remaining in the magazine via a high visibility indicator coil on the spring and numerical markers on the magazine body.

This proprietary capability—the MagLevel system—provides a fast round-count estimation without affecting the durability or reliability of the magazine. Like Magpul’s other PMAGs, the 20-round LR/SR GEN M3 Window magazine includes a stainless-steel, corrosion-resistant spring, along with an anti-tilt, self-lubricating follower. The magazine’s lines follow a constant-curve internal geometry for continuous reliable feeding. The low-profile ribs and aggressive front and rear texturing help give shooters a positive grip for magazine changes in all environments.

A paint pen dot matrix at the bottom panel of the body allows shooters to easily marking these magazines. In addition, a flared floorplate aids extraction and handling of the magazine and improves drop protection and ensures better compatibility with tight double- and triple-magazine pouches.

The magazine is also simple to disassemble and makes for easy cleaning and maintenance when necessary. Designed specifically for SAAMI-spec ammunition, the PMAG 20 LR/SR GEN M3 Window is less than half the weight of standard issue steel magazines and maintains a service life round count approximately equal to the rifle barrel itself.

MSRP is $24.95. Magpul PMAG 20 LR/SR GEN M3 Window magazines are avaialble in two colors, Black and Medium Coyote Tan. Learn more at magpul.com.
