    2. It's a recoil brake principle, combining friction and hydraulics. It's placed in that weird box you see around the barrel.

    1. ChKT-S1 airborne vehicle for the gun, sadly never built and there isn't much written about it. Although apparently that gun mount could also go on a Willis jeep. Beats a .30 cal!
