ABSTRACT:
A noise reducing booster insert of a sound suppressor coupled to a barrel of a firearm includes an elongate body, a plurality of gas vents, and a plurality of indexing spokes. The gas vents permit expanding gases from the firearm to fill a space about the body to thereby increase noise reduction without the need of modifying a baffle stack of the sound suppressor. The gas vents are angled such that the expanding gases force the booster insert to rotate into tighter threaded engagement with the barrel of the firearm.
