US12529539 - Integrally suppressed barrel system for velocity reduction of loads

Image unavailable

An integrally suppressed barrel system for a firearm, the system comprises a barrel having a series of transverse holes and a spiral groove forming machine-type threads of some dimension or specification, a gas block assembly configured to provide integration with the gas cycling system inherent to a firearm, a gas tube configured to protrude back into an upper receiver of the firearm, and a suppressor having a main housing. The main housing of the suppressor includes an inner wall, an outer wall, a series of holes and a base attached to the barrel through machine threads. The suppressor is fixed in a concentric pattern about the bore of the barrel.

The patent describes an integrally suppressed barrel system designed to reduce the velocity of loads in firearms, featuring a barrel with transverse holes, a gas block assembly, and a suppressor that surrounds the barrel. This system integrates with the firearm’s gas cycling mechanism and includes components that form a pressure chamber to enhance suppression efficiency.

Claim 1

1 . A suppressor system for a firearm, the suppressor system comprising: a barrel having a connecting end and a muzzle end, wherein the barrel includes a series of transverse holes along its bore, wherein the barrel is configured to be attached to an upper receiver of the firearm at the connecting end; a gas block assembly, wherein the gas block assembly is attached to an outer peripheral surface on a base of the barrel, proximal to the connecting end, wherein the gas block assembly comprises: a removable base cup configured to rest on a circular shoulder of the barrel; and a gas block cap configured to secure the removable base cup onto the barrel, wherein the removable base cup and the gas block cap form a pressure chamber therebetween; a pressure retainer attached to the barrel at the muzzle end; a suppressor housing configured to envelope the barrel, forming an enclosed chamber between the barrel, the gas block assembly, the pressure retainer and the suppressor housing; and a gas tube attached to the gas block assembly, wherein the gas tube protrudes back into the upper receiver of the firearm. a barrel having a connecting end and a muzzle end, wherein the barrel includes a series of transverse holes along its bore, wherein the barrel is configured to be attached to an upper receiver of the firearm at the connecting end; a gas block assembly, wherein the gas block assembly is attached to an outer peripheral surface on a base of the barrel, proximal to the connecting end, wherein the gas block assembly comprises: a removable base cup configured to rest on a circular shoulder of the barrel; and a gas block cap configured to secure the removable base cup onto the barrel, wherein the removable base cup and the gas block cap form a pressure chamber therebetween; a removable base cup configured to rest on a circular shoulder of the barrel; and a gas block cap configured to secure the removable base cup onto the barrel, wherein the removable base cup and the gas block cap form a pressure chamber therebetween; a pressure retainer attached to the barrel at the muzzle end; a suppressor housing configured to envelope the barrel, forming an enclosed chamber between the barrel, the gas block assembly, the pressure retainer and the suppressor housing; and a gas tube attached to the gas block assembly, wherein the gas tube protrudes back into the upper receiver of the firearm.
