Abstract
A compensator having an enlarged chamber is threaded onto the barrel of a handgun. The compensator has two equally sized, symmetrically positioned vertical upper ports aligned with matching ports in the threaded portion of the barrel, for vertically exhausting high pressure gas to produce a downward force that resists muzzle climb. The chamber also includes a pair of unequally sized, unsymmetrically positioned low pressure ports through which lower pressure gases are exhausted as the bullet leaves the chamber, compensating for rotation produced by the torque produced on the bullet by rifling of the barrel bore as the bullet accelerates.
Claims7
A compensating apparatus for resisting both muzzle climb and twist of a handgun in reaction to firing a bullet, the compensating apparatus comprising in combination:
- (a) a threaded end of a barrel of the handgun, and first and second high pressure gas outlet ports disposed on either side of an imaginary vertical plane passing through the center of a bore through the barrel and through a gunsight of the handgun;
- and
- (b) a compensator including a threaded bore receiving the threaded end of the barrel and also including an enlarged expansion chamber into which high pressure gas following a bullet being fired can expand, the compensator including third and fourth high pressure gas outlet ports aligned with the first and second high pressure gas outlet ports, respectively, the compensator also including first and second vertical low pressure gas outlet ports extending from upper surface portions of the compensator on either side of the imaginary vertical plane into the enlarged expansion chamber, the second vertical low pressure gas outlet port being substantially larger than the first vertical low pressure gas outlet port, the second vertical low pressure gas outlet port being located further from the imaginary vertical plane than the first vertical low pressure gas outlet port, whereby nonsymmetrically, non-radially discharged amounts of low pressure gas from the enlarged expansion chamber produce a countertorque resisting twist of the handgun due to counterforce applied by the accelerating bullet to rifling of the bore of the barrel, high pressure gas upwardly exhausted from the third and fourth high pressure gas outlet ports effectively resisting muzzle climb.
