Sound suppressor

Abstract

A monocore for a sound suppressor that significantly enhances the trapping and delay of the gases exiting from the sound suppressor due to the design, location, and configuration of slanted baffles and angled half-baffles, and a plurality of rods. The slanted baffles help define the blast chamber, expansion chambers, and exit chamber of the monocore. The plurality of rods may be positioned in the blast chamber or the expansions chambers. The plurality of rods may vary in length. The plurality of rods may also replace the angled half-baffles.
