A ballistic optimizing system for use on a rifle comprises an axially movable weight threadedly secured to the end of a rifle barrel such that movement of the weight can be used to change vibrational characteristics of the rifle when it is fired. By damping vibrations of the barrel at the muzzle, a bullet can exit the barrel at the point of minimal vertical deflection so that accuracy is improved. To secure the weight element into a desired position, a tooth on a spring carried on the weight is received into one of a plurality of axial grooves equally spaced around the circumference of the rifle barrel. Additionally, a compression spring in an annular space between the barrel and the weight applies greater frictional engagement between the threads of the weight and the threads of the barrel so that alignment of the weight with respect to the barrel is improved. Finally, a nylon insert can be placed in longitudinal grooves cut across the threads of the barrel to remove substantially all traces of play between the weight and the barrel.
