Benefits of technology
The piston design effectively reduces sound and flash signatures by allowing gases to cool and expand, while preventing unthreading due to vibrations, improving sound suppression without modifying the baffle stack and enhancing compatibility with existing booster designs.
Problems solved by technology
Some sound reduction may be gained from these designs but the noise inherent to the threaded insert being forced around inside of its housing also generates noise in its own right.
While the above represent designs which are functional for their primary purpose, to operate semi-automatic handguns, they do not provide for optimal sound reduction.
Vibration resulting from the discharge of the host weapon can cause a sound suppressor which is threadedly secured about a handgun barrel to unscrew.
This tightening works with varying degrees of success, but always leaves the potential of not being universally compatible with a variety of manufacturers' handgun barrels.

Embodiment Construction
[0019]Turning now to the drawings in which like reference characters indicate corresponding elements throughout the several views, attention is directed to FIGS. 1-4 which illustrate the preferred embodiment of a noise reducing booster insert 1, hereinafter referred to as the piston 1, and FIG. 5, which illustrates the piston 1 in use with a noise suppressor and a firearm 5. As shown in FIG. 1, the piston 1 includes gas vents 3 which are machined near a front or exit end 14 of the piston 1. Ten indexing notches spokes 2 with notches there between are also located at the exit end 14 of the piston 1.
[0020]In FIG. 2, there is illustrated a view of the exit end 14 of the piston 1. The number of indexing spokes 2 and how they are oriented are clearly illustrated. These spokes 2 and notches allow the user to change the rotational orientation of the host noise suppressor 6 and its baffles in relation to the barrel 7 of the firearm 5. By pulling longitudinally forward on the noise suppresso...

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.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]This device relates to handgun sound suppressors, specifically to coupling attachments which are threadedly secured about a handgun barrel which are designed to aid in sound reduction when used in conjunction with a noise suppressor. Further, this device aids in the prevention of the sound suppressor from unthreading from the handgun barrel due to the incidental vibrations related to discharging the firearm.[0003]2. Prior Art[0004]There is always a need to improve the sound reduction of a sound suppressor. Generally inventors focus on improving baffle design. The device of the invention works by manipulating the expanding gases exiting a firearm prior to contact with the blast baffle.[0005]Previous systems exist for attaching a sound suppressor to a handgun barrel. Devices such as the A.S.A.P system, commercially available from Advanced Armament Corp. of Norcorss, Ga., utilize a threaded insert which rest within a cylindric...
