Ares Shrike 5.56

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 name comes from the Shrike, a carnivorous passerine bird, and was designed by Geoffrey Herring.
