Thread: Ar57?

Anyone own one, experience one, or can tell me about one?

I saw two guys shoot one. Casings came down the magwell...which was kinda funny to look at. Keeps it from bouncing off of walls and hitting you, which is nice.

Recoil looked...like nothing. But knowing you , you might Upload the 5.7 to something deadly.

Wish I knew more.

Well here's what I know.
Cases feed from a $30 50 round magazine that runs the length of the upper. They eject downward into the mag well and a 30 round magazine will hold 50 cases for reloading. 5.7 delivers 2100 fps and 310Ft/lbs and is accurate out to ~250 yards. They are available in 16" 11" and 6" lengths and the 6" is made to be used with a 1.25" 9MM suppressor.

Is it okay to shoot 5.7 in a 9mm suppressor?

They still have it. I thought there was an issue with the mags, something about the plastic feed lips deforming after about a thousand rounds, or something like that...
