Steyr-Mannlicher GmbH & Co., A.G. Steyr introduces a whole new concept of AR15-based assault rifle, the STM-556!

The AR-15 is definitely the new AK, in that, being no longer the state of the art of individual weapons, its manufacturing technology is nowaday so widely spread that the number of Countries whose arms industry produces AR-15/M16/M4 variants increases day after day. The latest Country to jump on the AR-15 bandwagon is Austria, with Steyr-Mannlicher GmbH, the company known worldwide for the AUG bull-pup assault weapon system, announcing today the launch of its own variant of Eugene Stonerʼs platform. Called the STM-556, Steyrʼs new weapon system is built around two solid billet aluminium receivers, with a monolythic upper, a top MIL-STD-1913 Picatinny rail for optics and a quad-rail handguard for tactical accessories. Chambered − as of now − only in the NATO standard 5.56x45mm caliber and fed through STANAG 4179 magazines, the Steyr Mannlicher STM-556 rifle comes factory-equipped with MagPul MOE telescoping stock and pistol grip and MagPul flip-up iron sights. The controls reprise the latest standards in AR-15 configurations, and are ambidextrous.
