Abstract
A suppressor baffle and a suppressor for a firearm. The suppressor includes a firearm attachment portion, a sleeve portion, and a baffle assembly with a plurality of baffles. At least one of the baffles includes a tubular body with a proximal exterior surface. The proximal exterior surface has a plurality of spaced-apart annular ridges. A first annular ridge includes a first annular compression surface and a first annular expansion surface, and a second annular ridge includes a second annular compression surface. The ridges are shaped and arranged to define a convex first expansion corner between the first annular compression surface and the first annular expansion surface, and a concave first compression corner between the first annular expansion surface and the second annular compression surface. Gas flowing along the proximal exterior surface expands at the first expansion corner and compresses at the first compression corner to dissipate energy in the gas.
