Patent ID: 8714301

Claim:
A noise suppressor system for a firearm, comprising: a flash suppressor selectively mountable to a distal end of a barrel of the firearm, the flash suppressor having a base, a tapered waist portion and a shoulder surface; a noise suppressor comprising a plurality of baffles mountable in a housing; and a compressive coupling between a proximal end of the housing to the tapered waist portion and the shoulder surface of the flash suppressor the compressive coupling comprising: a proximal mount assembly coupled to the proximal end of the housing of the noise suppressor, the proximal mount assembly having a longitudinal axis, wherein the proximal mount assembly comprises: a cap base member having a plurality of rotatable cam members pinned in a plurality of slots defined in a base portion of the cap base member; and a proximal attachment cap that is rotatably coupled via interrupted complementary threads to the cap base member, wherein each cam member can be selectively rotatable by biased application of cam surfaces on portions of an interior surface of the proximal attachment cap upon rotation of the cap base member relative to the proximal attachment cap.
