Sound Suppressing Gun Barrel

摘要

A gun barrel for guiding a bullet along a longitudinal axis, the bullet having a diameter, the gun barrel having a circumferential series of lands, each land among the circumferential series of lands being radially displaced from the longitudinal axis a distance at least as great as one-half of the bullet's diameter, each land extending helically about the longitudinal axis; a plurality of sound reflection chambers, each sound reflection chambers among the plurality of sound reflection chambers being positioned between an adjacent pair of lands among the circumferential series of lands, each sound reflection chamber having a muzzle end, and each sound reflection chamber opening radially inwardly; and a plurality of sound reflection walls, each wall among the plurality of sound reflection walls closing one of the sound reflection chambers' muzzle ends.
