ABSTRACT:
A baffle configured for use in a firearm sound suppressor is disposed along a longitudinal axis that defines a path of travel for a projectile moving from a rearward side to a forward side. The baffle includes a rear bell portion having a first annular exterior surface and a forward bell portion having a second annular exterior surface. Along the longitudinal axis in a forward direction, the rear bell portion decreases in cross-section and the forward bell portion increases in cross-section. The baffle further includes a waist portion connecting the rear bell portion and the forward bell portion. A central bore extends along the longitudinal axis through the rear bell portion and defines an annular interior surface which is sized to receive a projectile traveling along the longitudinal axis. The baffle may be one of a plurality of baffles in a baffle stack.
