PRODUCT DESCRIPTION

P.W. Arms Complete AR57 16" GEN 2/LEM Upper Assembly in 5.7x28mm. Now with fluted barrel, updated railing system, charging handle, and magazine release. 1/2 by 28 threads, AR57 Flash Hider, S/A Bolt, and Carbine Buffer. Come complete with 1-50 round magazine and ready to drop in to any conventional AR-15 collapsible Stock Lower. Extra mags available.

The AR57 Upper Receiver Assembly converts any AR-15 lower to a rifle capable of shooting 5.7x28 FN ammunition. The unique upper design loads from the top and
ejects downward through the AR-15 magwell. This upper includes 1-50 Round magazine and accepts all AR-57 and FN PS90 magazine. Additional mags are readily available. 

This upper is precision machined from a one piece aluminum forging. The integrated picatinny-style quad rail system allows attachment of various accessories. A parkerized chrome alloy bolt and full-floated barrel ensure reliability and accuracy. The teflon-infused hard coat anodized aluminum upper and rails gaurantee durability for years of shooting enjoyment. The updated charging handle and magazine release of this Generation 2 rifle allows for easy manipulation of the controls and is very user friendly. The Gen II design also has new and improved  features, such as a fluted barrel, making it even more popular than the original Generation 1 upper assemblies. The top feed and bottom eject also help to make this upper fully functional for right or left handed users. A carbine style (3 1/2 inch) buffer is included, rifle length stocks require the AR57-A2 buffer (6 inch), which must be obtained seperately.

Comes complete with 1-50 round mag - additional mags available. If you are a lover of the 5.7x28 round, or just want something different that will impress your friends and perform like a work horse, the AR-57 is the rifle for you.
