Magpul PMAG 30 GEN M3 .300 BLK 30rd - AR-15 Magazine - ODG

The Magpul PMAG 30 GEN M3 .300 BLK magazine improves feeding reliability for AR-platform rifles chambered in .300 Blackout. Built for shooters running a wide range of bullet weights and profiles, this AR-15 magazine delivers dependable performance with enhanced durability and easy cartridge identification.

The PMAG 30 GEN M3 is an AR-15 magazine designed specifically for rifles chambered in .300 AAC Blackout. Its modified internal geometry supports the unique projectile shapes commonly found in .300 BLK ammunition, helping reduce feeding issues during training, defensive use, and range sessions.

Distinct external ribbing and a smooth upper texture provide quick visual and tactile differentiation from standard 5.56 NATO magazines to help minimize cross-loading mistakes. The impact-resistant polymer body resists cracking and deformation under hard use, while the aggressive texturing improves control during reloads in wet or dirty conditions.

This 30-round magazine is compatible with most STANAG-pattern AR-15 platforms, including M4-style carbines and many modern sporting rifles chambered in .300 Blackout. It also works with compatible PMAG accessories and Magpul Tactile Lock Plates for additional customization and identification options.

Constructed from next generation polymer, the magazine combines crush resistance with proven feed geometry for long-term reliability. The removable floorplate allows quick access for cleaning and maintenance, while the paint-pen dot matrix gives users a convenient way to label magazines for load organization.

Whether used for home defense, range training, or hunting applications, this dedicated .300 BLK magazine is designed to support consistent feeding across varied ammunition types and shooting conditions.
