  • Patent number: 6951072
    Abstract: A barrel bracket in the form of a split ring is secured adjustably to a gun barrel at any point on the barrel and at any desired angle of orientation. A hook pivotally attached to the ring has a sharp point for piercing external structures, such as trees, fences, or other wooden objects to secure the barrel to the structure and act as a gun rest. The hook closes with the point shielded so that the gun may be carried and used normally since the attached gun rest is light weight and has no large protruding structures. Alternately, a built in barrel bracket is positioned on one side or the other or one on each side for right handed and left handed shooters.

  • Patent number: 6763765
    Abstract: A gas check member for use in muzzle-loading firearms is provided. The invented gas check is designed to conveniently, frictionally attach rearward of a sub-caliber bullet to maximize the efficiency of such firearms. The diameter of the gas check preferably exceeds that of the bore slightly to prevent scoring and deformation of the bullet during loading, to hold the projectile in place within the barrel and to prevent moisture from contacting the powder when in place. Upon firing, the gas check minimizes the escape of propellant gases around the projectile and imparts a large, uniformly distributed forward thrust to the bullet to maximize the ballistic qualities of the shot. The design incorporates an unstable connection between inner and outer members that, upon firing, fractures to facilitate quick and reliable detachment of the outer member from the bullet. Detachment occurs to prevent interference with the trajectory of the bullet upon exit from the barrel.

  • Patent number: 6711842
    Abstract: A firing mechanism which allows a reduction in the overall length of a handgun by making use of space longitudinally forward of the breechface, beneath the barrel. The firing element is longitudinally slidable and has a projection which cooperates with a firing pin. A rebound spring acts on the projection and allows compatibility with a self cocking trigger. The required longitudinal space is further reduced by a longitudinal aperture through the firing element which allows the firing element to pass over the front of the driving spring guide.

  • Patent number: 6684873
    Abstract: A paint ball gun includes an agitator mounted on the end of a rotary motor shaft. Rotational direction of the motor shaft is controlled by an electronic circuit responsive to a tilt sensor. The inclusion of tilt sensor provides an enhanced paint ball gun capable of operating optimally during periods of gun tilt. Several preferred magazine designs incorporating the tilt sensor are illustrated. An additional double-rotation of the motor is disclosed which enables short bursts of oppositely directed agitator rotation, which frees any jams that may occur. These short bursts may be triggered manually, electronically responsive to a sensed condition indicative of a jam, or through a timed interval. The paint ball gun is capable of rapidly firing more paint balls under otherwise sub-optimal conditions than previously known in the art.

  • Patent number: 6684549
    Abstract: A recoil apparatus is provided for a firearm comprising a base portion and shoulder member coupled to a base portion and movable longitudinally with respect to the base portion upon firing of the firearm. A magnet system disposed in the base portion comprises a first magnet, a second magnet, and a third magnet. The first magnet provides a magnetic attractive force that prevents relative movement between the shoulder member and the base portion when the firearm is being aimed prior to firing. The second and third magnets are positioned in a repelling configuration with each other such that upon firing, the recoil of the firearm is dampened by the repulsive forces produced by the second and third magnets.

  • Patent number: RE38592
    Abstract: A multiple effect pyrotechnic shell (20), having a lift chamber (22), primary break (24), secondary break (26), and a tertiary break (28) has a desired weight distribution to inhibit tumbling. The secondary break weight is less than the primary break weight, and the tertiary break weight is less than both the primary and secondary break weights. Thus, the center of gravity of the shell (20) is positioned below a midpoint of the shell height. A first timing fuse (46) extends from a lift charge (30) into a primary break charge (50A) of the primary break (24), and a primary internal timing fuse (64) extends from the primary break (24) to the secondary break (26). Further, a secondary internal timing fuse (70) extends from the secondary break (26) to the tertiary break (28). Fuse fragments (52) are preferably disbursed within the break hulls (48) to provide filler and add an additional effect to each break (24-28).
