A bullet velocity enhancing rifle attachment assembly a sleeve having a first end, a second end and a perimeter wall. The sleeve has an aperture therein extending into the first end and outwardly of the second end. The aperture is defined by an inner wall including a first portion adjacent to the first end, an second portion adjacent to the second end and a central portion positioned between the first and second portions. The central portion has an toroidal shape. A coupler attached to the second end of the sleeve is releasably engageable with a gun barrel to align the aperture with the gun barrel. Pressure from a front side of a bullet traveling down the gun barrel is forced into the central portion to travel around the toroidal shape and back into the aperture toward the first portion, behind the bullet, as the bullet travels through the central portion. |
