Abstract
A silencer for a shotgun firearm comprises a metal body tube, a front end closure having a projectile exit guide, and a rear end closure having a barrel mounting element. A plurality of conical baffles with metal guide bushings are serially positioned in the body and arranged coaxially with the bore of the shotgun barrel. The guides are spaced apart a distance less than the axial length of the shot cup of the shotgun projectile. An expansion chamber is provided in the body rearwardly of the muzzle where the muzzle gasses are initially discharged into the body.

A shotgun silencer for a shotgun projectile having a compliant shot cup comprising;
- a closed body having front and rear ends, an interior wall and a longitudinal axis;
- a front end closure having a projectile exit guide bushing;
- a rear end closure having a mounting element for mounting the body to the barrel of a shotgun having a muzzle disposed within the body;
- and
- a plurality of baffles arranged in the body coaxially with the muzzle and each other and being spaced axially along the longitudinal axis of the body, each baffle supporting a metal guide bushing, said guide bushings being spaced apart less than the length of the shot cup and having a diameter substantially the same as the inside diameter of the barrel of the shotgun.
A method of making a shotgun silencer for a shotgun projectile having a compliant shot cup, the silencer including a cylindrical body, comprising the steps of:
- providing a plurality of identically formed baffles each supporting a metal guide bushing and having a cylindrical portion with opposite annular surfaces, each metal guide bushing having a diameter substantially the same as the inside diameter of a shotgun barrel to which the silencer is adapted to be attached;
- and
- inserting at least three of the baffles into the body in end-to-end relation such that the annular surfaces of the cylindrical portions bear against one another and the guide bushings of at least two adjacent baffles are spaced apart less than the length of the shot cup.
