Shot this yesterday at the range, my friend shooting his Slide Fire Stock on his AR-15 SBR with a 5.45x39 upper and SRT Hurricane can. Hope you find it interesting.
Slide Fire AR-15 Stock - 240fps
To be honest, that 5.45 upper was less than reliable, but the ammo is cheap. I occasionally would antagonize him by saying, "Something, Something, AR-15 reliability." The funny thing was that almost every time I said that, the gun would then go a full magazine with no jams.
Surprisingly easy to control. I was doing 2 and 3 round bursts no problem.
