The AR-57, also known as the AR Five-seven, is an upper receiver for the AR-15/M16 rifle lower receiver, firing 5.7×28mm rounds from standard FN P90 magazines. It was designed by AR57 LLC[3] and is currently produced by AR57 of Kent, Washington, USA. The AR-57 PDW Upper is a new design on an AR-15/M16 platform, blending the AR-15/M16 lower with a lightweight, monolithic upper receiver system chambered in FN 5.7×28mm. This model is also sold as a complete rifle, supplied with two 50-round P90 magazines.[1] The magazines mount horizontally on top of the front handguard, with brass ejecting through the magazine well. Hollow AR-15 magazines can be used to catch spent brass.
Unlike the standard AR-15 configuration which uses a gas-tube system, the AR-57 cycles via straight blowback.[4] A full auto version exists marketed as a competitor to the P90 and other personal defense weapons.[5]
