Suppressed upper receiver group having locking suppressor with through brake

Abstract

A suppressed upper receiver group for a firearm having a suppressor mounted to the barrel thereof. The suppressor has a tubular housing defining primary and secondary flow paths for propellant gas processing, diverting a portion of the propellant gas to the secondary flow path for pressure control. A number of baffle members are arranged in spaced relation within the housing and define serially arranged propellant gas processing chambers. A suppressor mounting adapter is connected with the barrel and has a propellant gas processing section having a propellant flow bore and extends completely through the housing and has a flash retarding tip projecting through a discharge opening of the housing.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention generally concerns firearms, such as rifles, and more particularly concerns sound and flash suppressors that are mounted by threading a generally cylindrical suppressor device onto the threaded end of the barrel of a firearm. More particularly, the present invention concerns a suppressed upper receiver group including an upper receiver mechanism and cartridge gas energized auto-loading mechanism and a barrel for a tactical rifle wherein a sound and flash suppressor device is provided at the forward end or muzzle of the barrel. Even more specifically the present invention concerns a sound and flash suppressor having a generally cylindrical suppressor body or housing having a muzzle brake device that extends completely through the tubular body of the suppressor body and is designed to substantially eliminate baffle strikes by hot gunpowder residue and thus significantly minimize the need for frequent cleaning...

AI Technical Summary

Benefits of technology

The present invention provides a firearm with a suppressed upper receiver cartridge that has a sound and flash suppressor that reduces the frequency of cleaning required to maintain optimal performance. The suppressor incorporates a collet clutching mechanism to securely mount the suppressor to the firearm without becoming loose or separating from the mounting adapter. The suppressor also has internal flow paths to prevent excessive back pressure or blow-back to the firearm barrel and ensures low pressure conditions within the suppressor for efficient sound suppression and substantially eliminating visible gunpowder flash. The suppressor mounting adapter includes propellant gas processing geometry to minimize buildup of propellant residue within the suppressor. The suppressor is securely mounted with the barrel using a locking collet and ratcheting surfaces prevent the locking ring from inadvertently backing off. The technical effects of the invention are improved firearm performance, minimized cleaning requirements, and reduced back pressure on the firearm barrel.

Problems solved by technology

Hot propellant gas striking the baffles and other components within a surpressor housing typically creates significant problems which until the present time there has been no reasonable solution.

In a relatively short period of time the buildup of propellant residue will cause the suppressor to begin to lose its optimum operational characteristics, requiring personnel to accomplish disassembly of the suppressor and thorough cleaning of the baffle members and other internal components as well.

Removal of this residue buildup is difficult and time consuming because of its essentially plated nature and requires cleaning equipment and expensive residue solvent to accomplish.
