Made in the USA, the PMAG D-6 is a durable, lightweight, reliable 60 round 5.56x45 NATO/.223 Rem polymer drum magazine for AR15/M4 compatible weapons. With a larger capacity the D-6 gives the shooter 60 rounds of ammunition, effectively allowing the same round count as two standard capacity 30-round magazines. The drum configuration keeps the height of the magazine manageable as well as allowing for prone firing and easier storage and will seat fully loaded on a closed bolt. Features an easy to use loading lever, paint pen dot matrix for easy marking and an anti-glare rear window for instant capacity indication. Designed to be left loaded for long term storage without any loss of function or degradation. Includes slip-on, semi-rigid dust cover. Compatible with a wide range of NATO firearms such as the M4, M16, SCAR MK16/16S, HK 416, MR556, M27 IAR, IWI Tavor and others.
