AR Five Seven Barrels & Choke Tubes ar57 upper receiver assembly, ar57p

Combining the modularity and comfort of the AR15 Rifle with the power and performance of the P90, the AR57 Upper Receiver Assembly is amazing. Chambered for the legendary 5.7x28mm round, the AR57 Upper Receiver Assembly uses standard P90 magazines, and when attached to an AR15 lower receiver, uses the mag well as an ejection port.
