Integrally suppressed barrel system for velocity reduction of loads
View Patent ↗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.
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.
2 . The suppressor system as claimed in claim 1 , wherein the removable base cup is configured to slip-fit on the circular shoulder on the base of the barrel.
3 . The suppressor system as claimed in claim 1 , the gas block cap comprises internal threads, and is configured to fasten onto a complementarily threaded portion of the base of the barrel.
4 . The suppressor system, as claimed in claim 1 , wherein the suppressor housing is a double-walled housing, comprising an inner housing wall and an outer housing wall attached concentrically with each other along a bore axis of the barrel.
5 . The suppressor system as claimed in claim 4 , wherein between the suppressor outer housing wall and the suppressor inner housing wall, a gap is created that contains air, gas or a combination of insulating materials.
6 . The suppressor system as claimed in claim 4 , wherein the gas block cap has an outermost diameter equal to that of the removable base cup, a first concentric shoulder equal to an internal diameter of the suppressor outer housing wall, and a second concentric shoulder equal to an internal diameter of the suppressor inner housing wall, wherein the suppressor inner and outer housing walls are connected to the gas block cap by means of a lip fit mating into the first and second concentric shoulders, respectively.
7 . The suppressor system as claimed in claim 1 , comprising a suppressor mount assembly configured to attach to the barrel of the firearm, wherein the suppressor housing is affixed to the barrel in a concentric pattern about the bore of the barrel through the suppressor mount assembly.
8 . The suppressor system as claimed in claim 7 , wherein the series of transverse holes about the bore of the barrel connects the pressure chamber parallel to the bore of the barrel, wherein the gas block assembly is integrated into the suppressor mount assembly via the removable base cup.
9 . The suppressor system as claimed in claim 1 , wherein the removable base cup is located radially in a position by way of a locating pin and notch feature formed into the outer peripheral surface of the barrel, opposite the gas tube and just forward of a barrel chamber.
10 . The suppressor system as claimed in claim 1 , wherein the gas block cap is a pressure transfer cap.
11 . The suppressor system as claimed in claim 1 , wherein the pressure retainer is located towards the muzzle end of the barrel and concentric to an inner housing wall of the suppressor housing.
12 . The suppressor system as claimed in claim 1 , comprising a monocore baffle attached to the muzzle end of the barrel.
13 . The suppressor system as claimed in claim 1 , wherein the gas block cap is mechanically affixed to inner and outer housing walls of the suppressor housing as a structurally supportive feature.
14 . The suppressor system as claimed in claim 1 , wherein the shoulder is a smaller diameter concentric circular portion slightly fore and almost coplanar to a barrel nut and offset from a muzzle of the barrel.
15 . The suppressor system as claimed in claim 1 , wherein the gas block cap comprises a series of holes radially arrayed about a bore axis of the barrel and equidistant from each other.
