The PMAG D-60 AR/M4 GEN M3 is a durable, lightweight, highly reliable 60-round 5.56x45 NATO/.223 Remington polymer drum magazine for AR15/M4 compatible weapons. With a larger capacity than previous PMAGs, the PMAG D-60 gives the shooter 60 rounds of ammunition, effectively allowing the same round count as two standard capacity 30-round magazines without requiring a critical reload. The unique drum configuration keeps the height of the magazine manageable as well as allowing for prone firing and easier storage. Features an easy-to-use loading lever, paint pen dot matrix for easy marking, and a rear window for instant capacity indication. Compatible with a wide range of NATO firearms such as the M4, M16, SCAR MK16/16S, HK416, MR556, M27 IAR, IWI Tavor, and others.
