Abstract
A gas pressure deflector system mounted on the exterior of a muzzle brake for a firearm barrel. The gas pressure deflector system comprises two deflectors adjustably positioned along the longitudinal axis of the brake to bracket the muzzle brake vent apertures. The deflectors create a pressure equalizing trap serving to smooth out the pressure pulse differential occurring along the muzzle brake gas venting region when a bullet is fired, thereby enhancing bullet accuracy and reducing recoil.
Claims23
An accuracy-improving gas pressure deflector system for use with a firearm muzzle brake, the muzzle brake having rearward and forward ends and including one or more vent apertures defining an elongated region of gas venting, the gas pressure deflector system comprising:
- a first rear deflector mounted on an exterior surface of the muzzle brake in association with a rearward portion of the gas venting region for directing gas from the venting region forwardly;
- a second front deflector mounted on an exterior surface of the muzzle brake in association with a forward portion of the gas venting region for directing gas from the venting region rearwardly;
- the first and second deflectors being mounted on the muzzle brake in a manner permitting adjustable positioning along a longitudinal axis of the muzzle brake in order to adjust the spacing between the first and second deflectors;
- the deflectors further being slidingly mounted on the muzzle brake for axial adjustment and detachably secured by set screws which fix the deflectors in place on the muzzle brake when tightened against the muzzle brake to permit sliding movement of the deflectors along the muzzle brake when loosened.
An accuracy improving gas pressure deflector system for use with a firearm muzzle brake, the muzzle brake having rearward and forward ends and including one or more vent apertures defining an elongated region of gas venting, the gas pressure deflector system comprising:
- a first adjustable deflector mounted on an exterior surface of the muzzle brake in association with a rearward portion of the gas venting region and including a deflector surface positioned such that gases venting from the venting region will impinge upon the deflector surface and be redirected forwardly;
- a second adjustable deflector mounted on the exterior surface of the muzzle brake in association with a forward portion of the gas venting region and including a deflector surface positioned such that gases venting from the venting region will impinge upon the deflector surface and be redirected rearwardly;
- the first and second deflectors being adjustably mounted on the muzzle brake for lengthwise movement and further including means for detachably securing the deflectors to the brake at a desired location to adjust the spacing between the deflectors, the position of the deflectors relative to the firearm barrel, and/or the extent of the gas venting region located between the deflectors.
An accuracy-improving gas pressure deflector system for use with a firearm barrel, comprising:
- a substantially tubular muzzle brake having a forward end and a rearward end, and one or more vent apertures defining an elongated gas venting region;
- a first axially-adjustable deflector mounted on the muzzle brake, and fastening means for detachably securing the first deflector at a desired location on the muzzle brake;
- a second axially-adjustable deflector mounted on the muzzle brake, and fastening means for detachably securing the second deflector at a desired location on the muzzle brake;
- wherein,
- the first and second axially-adjustable deflectors each comprise a deflector surface for redirecting gas from the venting region toward the other deflector to define an adjustable length pressure-equalizing trap therebetween to reduce a pressure pulse differential along the muzzle brake.
