ar upper
The AR-57, also known as the AR Five Seven , is a Lower receiver for the AR-15/M16 rifle and an Upper receiver, firing 5.7×28mm rounds from standard FN P90 magazines. It was designed by AR57 LLC and is currently produced by AR57 of Kent, Washington, USA. 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. 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. A full auto version exists marketed as a competitor to the P90 and other personal defense weapons.

PICKUP IN TANASBOURNE
I have only used this on a lower with Colt magazines, I'm not sure if it works with any other type. I bought this a few years back and it's had probably less than a thousand rounds through it. I have recently purchased a buffer less upper, and it only works with Glock magazines. I took off my...
My buyer backed out, so I'm putting it back up for sale... Cash only, pickup in Tanasbourne. $220 without the carry handle.
It's a classic AR upper with a 16" barrel 1:7 twist. Maybe 60 rounds through it. It looks as good as new.
Still learning as I go...so another question. Why would one use a two-piece gas tube???
After pulling the hand guard off what might be a Bear Creek .450 Bushmaster 16" upper, I noticed a faint line on the gas tube, it's hard to see...but definitely two pieces pressed together...
Any thoughts?
