Magpul PMAG Gen M3 .300 Blackout Black, Detachable 20rd Magazine For AR-15 - MAG1182-BLK

The PMAG 20 AR 300 B GEN M3 is a purpose-built magazine for rifles chambered in .300 Blackout® (300 BLK). Similar in every way to our PMAG 30 AR 300 B, the PMAG 20 is more compact for increased maneuverability and creates a more concealable package for use in small format firearms.

Since its inception, 300 BLK shooters have had to use a magazine designed for another cartridge, limiting that round’s ultimate performance and compatibility. One of the key features of 300 BLK in the past has been its compatibility with 5.56x45mm magazines. However, even with moderate success with that particular magazine, it is a compromise to do so, with reliability and safety both being at risk.

Product Features:

• Purpose-Built Magazine Only For 300 BLK
• Designed With Visual & Tactile Differences
• Incorporates the Same Features and Performance of the Gen M3 Line 
• Platform: AR15, M4, and M16
• Compatibility: Wide Compatibility With Most "STANAG 4179" platforms such as the AR15/M4, FN SCAR, IWI Tavor, and others.
