Recoil and muzzle blast controller for firearms

#1. Field of the Invention

#This invention relates generally to a recoil and blast controller (RBC), which may also be referred to as a muzzle brake, for a firearm that reduces the intensity of the recoil, the muzzle rise, and the muzzle blast effects produced by the high-pressure propellant gas as it flows out of the firearm barrel.

#2. Description of the Background Art

#The present invention will be more fully understood from the detailed description given below and the accompanying drawings which are given by way of illustration only, and thus, are not limiting of the present invention:

#FIG. 1 shows a model of the assembled RBC from the rear, where it screws onto the barrel of the firearm, in accordance with one embodiment of the present invention,

#FIG. 2 shows a model of the assembled RBC from the front in accordance with one embodiment of the present invention,

#The present invention is directed to a recoil and blast controller (RBC), which may also be referred to as a muzzle brake. In accordance with one embodiment of the present invention, FIG. 1 shows a model of the assembled RBC from the rear, where it preferably screws onto the barrel of the firearm, and FIG. 2 shows a model of the assembled RBC from the front. As illustrated in FIG. 3, the RBC in accordance with one embodiment of the present invention primarily includes two components: a tubular depressurization chamber 1 and at least one tubular buffer chamber housing 2. In a preferred embodiment, the RBC includes only these two components. It must be noted, however, that this specific two-component design has been developed to reduce production costs, and the design can also be manufactured as either a single piece or from more than two components. In this embodiment, the tubular depressurization chamber 1 is internally-threaded on its rear section so that it can screw onto external threads provided on a front section of the tubular buffer chamber housing 2. In a preferred embodiment, the tubular buffer chamber housing 2 is also internally threaded so that it can thread onto the muzzle of a firearm 3 providing a removable connection. Once threaded onto the muzzle of a firearm 3, the volume between the end of the muzzle and the interior front face of the tubular buffer chamber housing 2 forms an internally-vented buffer chamber 10. It must also be noted that although this embodiment includes only one internally-vented buffer chamber, it is possible to include multiple internally-vented buffer chambers of this design by threading together in series several tubular buffer chamber housings to provide additional recoil and blast reduction capabilities.

#In this embodiment, the interior front face of the tubular buffer chamber housing 2 and the exterior front face of the tubular depressurization chamber 1 have a central bore 5 that is co-axial with the muzzle of the firearm, and through which the bullet passes after leaving the barrel. The tubular buffer chamber housing 2 has at least one smaller buffer chamber opening 4 which allows high-pressure gas to flow from the internally-vented buffer chamber 10 into the tubular depressurization chamber 1. As pictured in FIG. 3, in accordance with one embodiment of the present invention, the smaller buffer chamber openings 4 are round, however the number, shape, size and position of these smaller buffer chamber openings 4 may be adjusted to accommodate different bullet calibers and propellant loads. In a preferred embodiment, there are 2-16 smaller buffer chamber openings 4. In one embodiment of the present invention, the tubular depressurization chamber 1 also has at least one smaller depressurization chamber openings 6 which allow high-pressure gas to flow from the tubular depressurization chamber 1 to the outside atmosphere. In a preferred embodiment, there are 2-16 smaller depressurization chamber openings 6. As pictured in FIG. 3, in this embodiment, the smaller depressurization chamber openings 6 are round, however the number, shape, size and position of these smaller depressurization chamber openings 6 may be adjusted to accommodate different bullet calibers and propellant loads, and to control how the high-pressure gas is released to the outside or reflected rearward toward the interior front face of the tubular buffer chamber housing 2. In addition, in this embodiment, the exterior front face of the front end of the tubular depressurization chamber 1 is shaped so as to reflect the high-pressure gas emitted through the smaller buffer chamber openings 4 rearward towards the muzzle of the firearm 3. In this embodiment, the exterior front face of the tubular depressurization chamber 1 is flat, but it may also have other shapes, including conical or spherical shapes, with either an externally- or internally-curved surface, in order to control how the high-pressure gas is reflected.

#In this embodiment, the tubular depressurization chamber 1 also has a series of slotted openings providing vents 7, 8, 9 which allow high-pressure gas to flow from within the tubular depressurization chamber 1 to the outside atmosphere. As pictured in FIGS. 3 and 5, in this embodiment, the assymetrically-arranged vents 7, 8, and 9 have differing widths and lengths, however the number, shape, size and position of these openings may be adjusted to accommodate different bullet calibers and propellant loads, and provide different amounts of resistance to muzzle rise.
