Patent ID: 8579075

Claim:
A firearm silencer comprising: a proximal end and a distal end, a longitudinal passageway configured to permit a projectile discharged from a firearm to enter at the proximal end, pass through the silencer, and exit at the distal end, a plurality of substantially conical baffles, situated along the passageway, each of the baffles being spaced from one another such that proximal and distal chambers are formed; each baffle comprising: an exterior surface facing the proximal chamber and narrowing in the direction of the proximal end, and an aperture at the proximal end of the exterior surface, the aperture positioned to form part of the passageway; wherein the exterior surface of the baffle comprises at least one flute, the flute comprising a depression in the exterior surface which is concave when viewed from the proximal chamber and which increases a surface area and volume of the exterior surface of the baffle to create turbulence and increase sound reduction.
