Abstract: A firearm accessory rail adaptor bracket includes a bracket body, a rifle attachment jaw assembly carried by the bracket body, a first jaw operating mechanism provided in the rifle attachment jaw assembly, a pistol attachment jaw assembly carried by the bracket body and a second jaw operating mechanism provided in the pistol attachment jaw assembly.

Abstract: The dynamically configurable controlled fragmentation insert mechanism of this invention includes an assembly of three or more sleeves with differing through hole patterns thereon, that fit inside the shell casing. The individual sleeves can move independently of one another and a simple pinning mechanism holds the parts in place for a selected configuration. The warfighter can realign the insert sleeves by to create different geometric patterns of holes, each designed to engage a different target set with optimally sized fragments. The aligned patterns of holes creates individual geometric shapes that focus high-velocity jets to cut into the steel shell casing to correlate to the through-holes in the aligned patterned sleeves. Realigning the insert sleeves changes the through-hole pattern to produce different fragment sizes and mass distributions.

Abstract: A high feed ramp for use in Colt 1911 style handguns including a feed ramp on the frame (receiver) for guiding bullets into the barrel of the gun; a boiler room (barrel breech) with a small chamfered around its entire inner circumference; and an integral relief rim extension on the upper edge of the feed ramp, such that the feed ramp is extended over the bottom edge of the chamfered boiler room; wherein when the handgun is fired the bullets easily enter into the barrel and do not jam or misfire.

Abstract: A weapon stabilization platform assembly employing the action of the devices' telescoping tubular horizontal width adjustment attaching to the vertical roll over posts of a recreational off road 4×4, off road UTV, or other utility vehicle or frame vehicle by the nut and bolt compression of two bracket couplings or other attaching appliances fixed at the opposing end of each of the telescoping tubes. In a preferred embodiment, the device comprises a plurality of telescoping tubes being an outer sleeve and an inner sleeve that is sized to permit it to move horizontally in telescopic relationship to the outer sleeve, both sleeves being harbored within an anti-vibration foam cushion, being then sheathed within a protective fabric sleeve.

Abstract: A multi-celled ram-air parachute possessing one or more internal one-way valved air passages between at least two parachute cells to maintain positive air pressure within the parachute for the purpose of maintaining shape and rigidity when less than optimal airspeed is present thereby increasing a user's control and safety.

Abstract: A powder charged rock cracker cartridge (1) comprises a substantially cylindrical outer sleeve (2) with an end wall in a first end (3); a plug (4) which, enclosing said outer sleeve, is inserted into and is secured in an opposite second end of the outer sleeve; a main chamber (5) in the outer sleeve (2) between said end wall and said plug, which main chamber is filled with a blasting powder charge (6); a substantially cylindrical inner sleeve (7), which is coaxial with the outer sleeve (2), is connected to said plug, and extends into the charge of blasting powder in the main chamber; and a central through hole (8) in said plug which communicates with the inner sleeve, which is closed in its inner end, which is inserted into the blasting powder charge. The hole in the plug and the inner sleeve in combination form a priming chamber (9) having a shape corresponding to the outer shape of a detonator (10), which can be trigged electrically and comprises an igniting powder charge.
