A so called machine or automatic gun having a cone shaped device mounted about the gun muzzle, a washer like or ring member slidably affixed to the gun stock, a muzzle blast deflector device and a ball joint swivel device. The muzzle blast causes the muzzle to be deflected about the inner circular confines of the cone. In this manner, a somewhat circular bullet dispersion pattern is obtained. The size of the circular dispersion pattern may be adjusted by forward/rearward movement of the ring member to control the motion of the muzzle during the burst firing.
