  • Quick aim reticle
    Patent number: 11041694
    Abstract: A method of creating a rifle and scope assembly, that begins with selecting and providing a rifle having a caliber and barrel length and providing a selection of rifle scopes, wherein each one is matched to a caliber and barrel length. Then, a rifle scope that matches the caliber and barrel length of the rifle is selected from the selection of rifle scopes. The rifle scope is attached to the rifle. Then, a cartridge type is selected to be used in the rifle. A range to zero the rifle scope is selected, based on caliber, barrel length and cartridge type. The final step is zeroing the rifle scope to the selected range.

  • 3-cycle 2-stroke damper
    Patent number: 11002500
    Abstract: A trigger activated arm may use a piston moving within a cylinder to dampen gun bolt speed. In some embodiments, gun bolt motion increases pressure within the cylinder bore to dampen rearward gun bolt speed. The pressure may be high enough to unseat the cylinder creating a vent that cylinder fluid exits. In other embodiments, gun bolt motion decreases pressure within the cylinder bore to dampen forward gun bolt speed.

  • Method for operating gun having multi-drive link feed system
    Patent number: 10921074
    Abstract: A method of feeding rounds of linked, or un-linked, ammunition to a gun includes a motor-driven chain drive which rotates about a track. A rotatable feeder engages the ammunition to feed an ammunition round into a round extractor/retractor. A rotatable round positioner receives an ammunition round from the round extractor/retractor, and rotates it to a firing position. A main geneva wheel, mounted near the chain drive, is sequentially engaged by first and second drive rollers, secured to the chain drive, for being periodically rotated thereby. Drive pins of the main geneva wheel sequentially engage radial slots in a belt/round feed geneva wheel and a round positioning geneva wheel for timed rotation thereof to synchronize the operation of the round feeder and round positioner.
