Magpul
Industry-standard polymer AR magazine
The Magpul PMAG Gen 3 (Gen M3) is the industry-standard polymer magazine for AR-15 pattern rifles, representing over a decade of continuous refinement based on real-world combat feedback and rigorous testing. Trusted by military, law enforcement, and civilian shooters worldwide, the Gen M3 has become the default choice for anyone building or maintaining an AR-15.
Built from Magpul's next-generation crush-resistant polymer, the Gen M3 features completely redesigned internal geometry with a four-way anti-tilt follower and constant-curve feed path that ensures reliable feeding in all conditions. External improvements include low-profile ribs, aggressive front and rear texturing for positive grip, and a flared floor plate with improved drop protection for easier magazine changes.
Real-world performance has proven the PMAG Gen M3 to be exceptionally reliable across diverse environments and conditions. The magazine is designed to be left loaded for extended periods without spring fatigue. Users consistently report thousands of rounds through their PMAGs with zero malfunctions, making it the default choice for anyone building a serious AR-15. The redesigned bolt catch notch improves clearance on all platforms, and the over-travel stop prevents over-insertion on compatible weapons.
