MATCHED MUZZLE BRAKE-WEIGHT SYSTEM FOR FIREARMS
A matched muzzle brake and weight system mountable on a firearm barrel is disclosed. In certain embodiments, the muzzle brake and weight are configured to have the same predetermined weight and center of gravity so that the point of aim of the firearm remains substantially unchanged when a user deploys either the muzzle brake or weight. The system permits convenient interchangeability between the muzzle brake and weight without the need for re-sighting the firearm thereby maintaining accuracy. In some embodiments, the centers of gravity of the muzzle brake and weight are located at the same position with respect to a common reference point defined by the barrel. A method for using the system is also disclosed.

The present application claims the benefit of priority to U.S. Provisional Application No. 61/569,565 filed Dec. 12, 2011, which is incorporated by reference herein in its entirety.
BACKGROUND OF THE DISCLOSUREThe present disclosure generally relates to firearms, and more particularly to a muzzle brake and weight system for firearms including rifles.
Muzzle brakes or recoil compensators counter both the recoil effects and unwanted rising of the barrel upon firing a firearm by laterally and radially venting, combustion gases from the barrel in addition to axially through the forward open muzzle end of the barrel. This provides greater shot-to-shot accuracy for the marksman, which is essential particularly in the context of competitive shooting when using rifles to shoot targets at long distances where a slight deviation in point of aim typically results in large inaccuracies at the target end.
Muzzle brakes are typically attached via a threaded or other type connection to the muzzle end of the barrel. To compensate for the added weight and effect on the balance and center of gravity or mass of the barrel with the muzzle brake in place, the user may make appropriate adjustments in the sighting system of the rifle to recalibrate and improve accuracy.
In some instances, a user may elect not to use the muzzle brake which are known to increase noise and concussive effects on the shooter and others nearby. When the muzzle brake is removed, the user must now make adjustments to re-sight the rifle to compensate for the reduction in weight and effect on the balance or center of gravity or mass of the barrel to regain accuracy.
An improved muzzle brake system for allowing a user to shoot with either the brake mounted or dismounted without having to re-sight the firearm each time when changing operating modes is desired.
SUMMARY OF THE DISCLOSUREA matched muzzle brake-weight system according to some embodiments of the present disclosure includes a muzzle brake and a muzzle weight. Both components are interchangeable and releasably mountable to the muzzle end of a firearm barrel. The muzzle brake and weight are each precisely configured, dimensioned, and weighted to have the same weight and center of gravity or mass, thereby allowing the interchangeable use of either component without having to adjust and re-sight the firearm for accuracy.
In one embodiment, a matched muzzle brake and weight system for a firearm barrel defining a longitudinal axis is provided. The system includes a muzzle weight configured for mounting on a distal muzzle end of the firearm barrel, the muzzle weight having a weight and a generally cylindrical body defining a first axial passageway configured for a bullet or slug to pass through; and a muzzle brake configured for mounting on the distal muzzle end of the firearm barrel, the muzzle brake having a weight and a generally cylindrical body defining a second axial passageway configured for a bullet or slug to pass through, the muzzle brake including a plurality of radially oriented venting holes in fluid communication with the second axial passageway for venting combustion gases. The muzzle weight and muzzle brake each have a respective center of gravity located at an identical point in three dimensions with respect to the firearm barrel to maintain a uniform point of aim for the firearm when either the muzzle weight or brake are interchangeably mounted on the firearm barrel. In certain embodiments, the muzzle brake and muzzle weight have an identical predetermined weight.
In one embodiment, a matched muzzle brake and weight system for interchangeable mounting on a firearm barrel having a bore and defining a longitudinal axis is provided. The system includes an elongated muzzle weight configured for mounting on a distal muzzle end of the firearm barrel, the muzzle weight having a center of gravity and cylindrical body defining a first axial passageway coaxially aligned with the bore of the firearm barrel when the muzzle weight is mounted on the barrel; and an elongated muzzle brake configured for mounting, on the distal muzzle end of the firearm barrel, the muzzle brake having a center of gravity and cylindrical body defining a second axial passageway coaxially aligned with the bore of the firearm barrel when the muzzle brake is mounted on the barrel, the muzzle brake including a plurality of radially oriented venting holes in fluid communication with the second axial passageway for venting combustion gases. When either the muzzle weight or muzzle is mounted on the firearm barrel, their respective centers of gravity are located at a same axial position with respect to a common axial reference point defined by the firearm barrel to maintain a consistent point of aim for the firearm when either the muzzle weight or muzzle brake are interchangeably mounted on the barrel.
A method for using a matched muzzle brake and weight system for a firearm is provided. The method includes: mounting the muzzle brake having a cylindrical body and first center of gravity on a muzzle end of a firearm barrel having a bore, the muzzle brake including a plurality of radially oriented venting holes; coaxially aligning a first axial passageway defined by the muzzle brake with the bore of the firearm barrel; locating the first center of gravity of the muzzle brake at a first axial distance measured from a common reference point defined by the firearm barrel; removing the muzzle brake from the barrel; mounting the muzzle weight having a cylindrical body and a second center of gravity on a muzzle end of a firearm barrel; coaxially aligning a second axial passageway defined by the muzzle weight with the bore of the firearm barrel; and locating the second center of gravity of the muzzle weight at the same first axial distance measured from the common reference point defined by the firearm barrel. A consistent point of aim for the firearm is maintained when either the muzzle weight or muzzle brake are interchangeably mounted on the barrel. In one, the method further includes the steps of coaxially aligning the first center of gravity of the muzzle brake with a longitudinal axis defining b the bore of the firearm barrel after mounting the muzzle brake on the muzzle end of a firearm barrel; and coaxially aligning the second center of gravity of the muzzle weight with the longitudinal axis defined by the bore of the firearm barrel after mounting the muzzle weight on the muzzle end of a firearm barrel. The muzzle weight may alternatively be mounted first on the muzzle end of the firearm barrel.
