Suppressor with Coaxial Expansion Chambers and Tapered Seals

A firearm suppressor for dissipating the energy of discharge gases expelled by a discharge of a firearm, the suppressor comprising:

• at least a first baffle and a second baffle, each baffle having a circumferential outer wall for enclosing an expansion chamber, the outer wall having a circumferential forward tapered surface and a circumferential rearward tapered surface, a taper angle of the forward tapered surface being equal to a taper angle of the rearward tapered surface;
• wherein the baffles are assembled together in a coaxial baffle stack with the first baffle forward of the second baffle, the forward tapered surface of the second baffle mating with the rearward tapered surface of the first baffle for forming a tapered seal between the outer walls of the baffles, thereby limiting flow of firearm discharge gases from within the baffle stack through the tapered seal;
• wherein the outer wall of each baffle comprises internal threads and external threads, the internal threads of one of the baffles engaging the external threads of the other of the baffles, forming a threaded engagement for retaining the baffles together in the stack;
• and
• wherein the tapered seal is located between the expansion chambers and the threaded engagement.
