The Ares Defense Shrike 5.56 is an air-cooled, dual-feed light machine gun/rifle for semi or full-auto configurations that fires the 5.56×45mm NATO cartridge. The Shrike 5.56 is sold as either as a complete weapon, or as an upper receiver "performance upgrade kit" to existing AR-15 and M16-type service rifles and carbines.
The weapon can be fed from a loose belt, separate belt boxes, or clip-on ammunition pouches for 100 rounds. It has a cyclic rate of fire of around 650–730 rounds per minute. There is a high degree of parts commonality between the Mk48, M249 and Mk46 machine guns, which simplifies maintenance and repair.
The system consists of a stabilized firing platform, a fire-control system and control grips. Several weapons can be mounted to the platform, such as: M2 Browning 12.7×99 .50 BMG heavy machine gun; NSV 12.7×108 heavy machine gun; M240/FN MAG 7.62×51mm NATO general-purpose machine gun; M249/FN Minimi 5.56×45mm NATO light machine gun
