The new AR-57 Upper Receiver. Includes free 50rd AR-57 Magazine where legal! This highly anticipated upper is a direct replacement for your standard AR upper that will allow you to shoot the FNH 5.7 round. This upper requires no FFL to purchase or receive, and we can ship directly to your home! (Fluted barrel is not available at this time)

The AR-57 platform empowers the operator with 50 rounds of firepower while keeping the magazine out of the way, increasing maneuverability and speed in close quarters conflicts. In addition to it's compact, snag-free design, the spent shells are directed straight towards the floor by exiting the standard AR magwell.

The upper receiver and rails are precisely milled from a monolithic block of aircraft grade 7075 T6 aluminum. Any sighting systems mounted on the rails will stay zeroed through the toughest of missions.

Designed with reliability as its primary feature. There is no gas system to become clogged with carbon or fouling and maintenance is a snap. The bolt and chamber stay clean through extended shooting sessions.

This new offering defines "High speed, low drag".
