US Patent 8973481 Firearm sound suppressor

In one example, a firearm sound suppressor includes a housing, a baffle, and an inner sleeve adapted to be disposed within the housing and to substantially surround the baffle. The inner sleeve includes a sidewall adapted to slide against the housing to permit the inner sleeve with the baffle to be selectively inserted into and removed from the housing without the baffle contacting the housing, and a longitudinal split extending through the sidewall and between front and rear ends of the inner sleeve to permit the sidewall to flex to permit removal of the baffle from the inner sleeve. Other embodiments are also contemplated.
