The AR57 PDW Upper is the most revolutionary new design on an AR15/M16 platform.  Blending the near perfect ergonomics of the ubiquitous AR15/M16 lower with a light weight, fast handling monolithic upper receiver system chambered in the 21st century’s exciting new caliber – 5.7X28mm.


Complete reliability, simplicity of design, and utterly low maintenace are hallmarks of the AR57. The ground breaking 50 round magazine, innovated and produced by FN Herstal, is the heart of this exceptional system. Top and forward mounted on the AR57 upper receiver, directly above the barrel for optimum balance and exceptional shoot ability, allows the shooter to take best advantage of cover and concealment. There is no magazine in the way to force the operator up off the deck and into the path of incoming fire. The shooter will also notice that he can place his support hand and arm directly under the rifle where it belongs and obtain a perfect shooting position in off-hand, kneeling and prone positions.


The upper receiver and rails are precisely millled from a monolithic block of aircraft grade 7075 T6 aluminum. Any sighting systems mounted on the M1913 Picatiny rails will stayed zeroed through the toughest of missions. Designed with reliability as it’s primary  feature. There is no gas system to become clogged with carbon or fouling making any maintenance a snap. The bolt and chamber stay clean well beyond extended shooting sessions.


The AR57 PDW Upper receiver comes with a ER Shaw barrel,  precision manufactured for exceptional accuracy and extreme durability – offered in numerous lengths and features.
