PW Arms AR57 PDW 5.7X28MM UPPER W/RAILS for AR15 Lower

PW Arms Gen2 Upper, AR57LEM, 5.7x28mm, 16" Fluted Barrel, Black Finish, Lightweight, with Quad Rail 

The AR57 PDW Upper is a low cost, high quality method to quickly change calibers to the latest Personal Defense Weapon (PDW) round: the 5.7x28mm.  This round is used in the famous FN P90 and this upper offers a revolutionary new design on an AR15/M16 platform. Blending the near perfect ergonomics of the ubiquitous AR-15/M16 lower with a light weight, fast handling monolithic upper receiver. Very low recoil, super high round capacity, ultra reliable and a 21st century ballistic round make this a remarkable next generation upper!

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. Expended shell casings drop straight down through the empty AR15 magwell for ease of collection and no hot brass on your neighbor! 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.
