History

Venezuelan soldiers who defected to Juan Guaidó were photographed using an AR-57 during the crisis in Venezuela in 2019.[4][5]

Design

The AR-57 PDW upper is a new design on AR-15/M16 rifles, 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 casings.

Unlike the standard AR-15 configuration which uses a gas-tube system , the AR-57 cycles via straight blowback.[6] A fully automatic version exists and was marketed as a competitor to the P90 and other personal defense weapons.[7]
