  • Apparatus for mitigating recoil and method thereof
    Patent number: 6745663
    Abstract: A recoil-mitigated projectile-firing device comprising a firing assembly, the firing assembly comprising the projectile-firing device secured within a tube and the recoil-mitigated projectile-firing device further comprising a brake assembly surrounding a portion of the tube. The brake assembly comprising at least one brake shoe supported within a frame and means for urging the at least one brake shoe against the outer surface of the tube. When the projectile-firing device is discharged, the firing assembly moves relative to the brake assembly and the frictional force mitigates the recoil.
