US 2015/0090105 A1 · Firearm Receiver Having an Integral Suppressor Assembly

Abstract

An integral suppressor assembly including a trunnion integrally extending from the front of the upper receiver, a tubular hand guard mounted to the trunnion, and a suppressor baffle mounted to the rifle barrel within the hand guard. The trunnion provides a structural interface for connecting the hand guard to the upper receiver, as well as the rifle barrel. The suppressor baffle seats within and encloses the muzzle end of the hand guard and is detachably connected to the end of the rifle barrel The interior of the hand guard forms a large expansion chamber around the barrel that works in conjunction with the suppressor baffle to reduce the noise signature of the weapon. The suppressor baffle is configured to have vent channels that direct the expanding combustion gases expelling the bullet from the barrel rearward into the expansion chamber of the hand guard before ultimately venting through the suppressor baffle.

Dependent claims

A suppressor assembly for a firearm having a receiver and a barrel mounted to the receiver, the integral suppressor assembly comprising:

an elongated tube detachably mounted to the receiver to extend over and axailly spaced from the barrel to define an enclosed interior tube space therein and around the barrel, the tube having a first end and a second end thereof, the first end of the tube adapted to be detachably mounted axially to the receiver to enclose and seal the first end of the tube;
and
a suppressor baffle adapted to detachably connect to the barrel and seat within the second end of the tube to seal and enclose the second end of the tube, the suppressor baffle having an axial bore there through aligned with the barrel, the suppressor baffle also having a vent channel defined therein,
the vent channel of the suppressor baffle in open fluid communication with the axial bore of the suppressor baffle and the interior of the tube for directing combustion gas from the discharge of a bullet from the firearm receiver into the hand guard interior tube space between the receiver and the suppressor baffle before venting through the axial bore of the suppressor baffle.

An Integrally suppressed receiver for a firearm comprising:

a receiver having an integral trunnion part, the trunnion having an axial bore extending there through, the axial bore configured to define an annular shoulder and a threaded female section;
an elongated barrel extending axially from the trunnion part, the barrel having a first barrel end and a second barrel end;
a barrel nut having an axial bore for receiving the barrel there through and a threaded male shaft turned into the threaded female section of the trunnion part for securing the barrel first end to the trunnion part;
an elongated tubular hand guard defining an interior thereof and having a first hand guard end and a second hand guard end, the first hand guard end detachably mounted axially over the trunnion part so that the hand guard covers the barrel and encloses the first hand guard end;
and
a suppressor baffle detachably connected to the second barrel end and seated within the second hand guard end to enclose the second hand guard end, the suppressor baffle having an axial bore there through aligned with the longitudinal axis of the barrel, the suppressor baffle also having a vent channel defined therein, the vent channel of the suppressor baffle in open fluid communication with the axial bore of the suppressor baffle and the interior of the hand guard for directing combustion gas from the discharge of a bullet from the receiver into the hand guard interior between the trunnion part and the suppressor baffle before venting through the axial bore of the suppressor bore.
