The PMAG 20 is a 20 round 5.56x45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. The PMAG 20 is optimized for Colt-spec AR15/M4 platforms, but its modified internal and external geometry also permits operation with a range of weapons such as the HK 416, MR556A1/M27 IAR, British SA-80, FN SCAR MK 16/16S, and others. It features a USGI-spec stainless steel spring for commonality, four-way anti tilt self lubricating follower, and constant-curve internal geometry for smooth feeding. It also features a redesigned bolt catch notch in the rear to increase bolt catch clearance, a pop-off impact/dust cover, and flared floor plates to aid in magazine handling and disassembly. Ribbed gripping surfaces and aggressive front and rear texture impact positive magazine handling, and paint pen dot matrix panels on the bottom of the body of the magazine allows for identification marking.
