Suppressor baffle
A suppressor baffle includes a cone portion expanding along a central axis from a proximal end defining a projectile opening to an open distal end having an outer rim. The projectile opening is in an entrance plane oriented obliquely to the central axis. A first volume between a first side of the cone portion and a central plane that includes the central axis is smaller than a second volume between an opposite second side of the cone portion and the central plane. At least part of the outer surface of the second side of the cone portion has a convex profile as viewed along the central plane from a side of the suppressor baffle. In another example, a first part of the cone is axially offset from an opposite second part of the cone, resulting in a curved projectile opening profile and a curved outer rim profile.
