The AR-57, also known as the AR Five Seven, is available as either an upper receiver for the AR-15/M16 rifle or a complete rifle, firing 5.7×28mm rounds from standard FN P90 magazines.[1][2]
It was designed by AR57 LLC.[3]
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 5.7×28mm. This model is also sold as a complete rifle, supplied with two 50-round P90 magazines.[4] The magazines mount horizontally on top of the front handguard, with brass ejecting through the magazine well. AR-15/M16-based STANAG magazines can be used to catch spent casings by taking out the feed lips, spring and follower.[5] Sheet metal brass catchers can also be used on the AR-15/M16 lower.[5]
Various scopes and other accessories can be mounted on the picatinny rail.[6]
Unlike the standard AR-15 configuration which uses a gas-tube system, the AR-57 cycles via straight blowbackTemplate:Broken anchor.[7] A fully automatic version exists and was marketed as a competitor to the P90 and other personal defense weapons.[8]
Suppressed versions are also available.[8]
