Magpul PMAG 20-Round AR-15 300 Blackout Magazine

Magpul PMAG 20 AR 300 B GEN M3: Precision and Safety in a Compact Form

The Magpul PMAG 20 AR 300 B GEN M3 is the quintessential magazine for rifles chambered in .300 Blackout (300 BLK). Designed with precision and purpose, this magazine addresses the unique demands of the .300 Blackout cartridge, offering unparalleled performance where it matters most.

This magazine stands out due to its compact size compared to its sibling, the PMAG 30. The reduced capacity provides increased maneuverability and makes it an ideal choice for those seeking a more concealable package in small format firearms. For shooters who require agility without compromising on reliability, the PMAG 20 delivers.

Traditionally, .300 Blackout enthusiasts have had to settle for magazines designed for other calibers—specifically those intended for use with 5.56x45mm rounds. This compromise often led to suboptimal performance and posed safety risks due to potential cross-loading issues. The distinct ribbed design of the PMAG 20 offers both visual and tactile cues that prevent such dangerous mix-ups, ensuring confidence every time you load your rifle.

Engineered from next-generation impact- and crush-resistant polymer, this magazine incorporates all of Magpul's GEN M3 features that seasoned users have come to trust: aggressive front and rear texture ensures secure handling; an easily removable slim floor plate facilitates quick maintenance; a paint pen dot matrix allows easy marking for identification purposes; plus a dust/impact cover keeps debris at bay during transport or storage.

A product born from necessity yet refined through innovation—the Magpul PMAG 20 AR 300 B GEN M3 represents not just another accessory but an essential component crafted specifically with your firearm’s optimal function in mind. Proudly made in the USA, it's not merely about loading ammunition—it’s about enhancing your shooting experience safely while maximizing efficiency on every shot fired.
