Abstract: A system where a group of substantially universal pre-manufactured explosive pellet assemblies are provided for on-site forming of shaped charges. That is, a specifically tailored liner may also be separately provided to the worksite/oilfield and combined with any one of the pellet assemblies so as to form a shaped charge having characteristics that are determined by the particular liner used. In this manner, hazardous shipping of fully assembled shaped charges may be avoided while at the same time allowing the operator a full range of shaped charge performance options based on the availability of uniquely tailored performance determinative liners that are also provided to the oilfield location.

Abstract: A system and method for ballistically cutting a multi-link metal chain comprises a chain alignment module that comprises three pins and attaches to the barrel of a firearm. A first pin and a second pin of the module fit on opposite sides of a target link of the chain. A third pin of the alignment module goes through a link adjacent to the target link of the chain. The three pins align the target link so that a bullet exiting the barrel of a firearm impacts a semicircular region of the target link to cause the target link to open.

These side ballistic plates may overlap the first and second plates. The side plates can have another ballistic plate mounted on their unconnected ends such that another assembly of first, second and side ballistic plates identical as above may also be connected. After connecting this second assembly, the user(s) would have full 360 degree ballistic coverage.

Abstract: A portable shooting bench and utility table. In the shooting-bench embodiment, a tabletop is isosceles-triangle-shaped for ambidextrous functionality. In the utility-table embodiment, the tabletop is preferably round but can be any shape suitable for general use. The shooting-bench embodiment preferably includes a height-adjustable seat. A plurality of ratcheting leg couplers are rotatably attached to a support base and radiate outward from the support base. A proximate end of a leg attaches in ratcheting fashion to each ratcheting leg coupler, allowing adjustment of an angle of declination of each leg. The ratcheting leg couplers rotate about the support base, allowing radial positioning of the legs for optimum stability under various terrain conditions. The shooting bench or utility table can be converted from a deployed mode to a folded mode, in which shoulder straps can be affixed to the tabletop allowing transport of the shooting bench or utility table backpack-style.

Abstract: A claw mounting system for a firearm stand engages with a sling stud of a firearm so that the firearm can be securely attached with the firearm stand. The claw mounting system includes an elastically loaded claw assembly, a securing member, and a bracket member as the securing member is threadly engaged with a sleeve portion of the bracket member while a left claw member and a right claw member of the elastically loaded claw assembly are tensionaly connected to each other through a spring-tension unit. The left claw member and the right claw member are also hingedly connected to a first tab of the bracket member through a retainer channel and a retainer pin. The claw mounting system greatly reduces the mounting process time of a firearm by remaining in a stable vertical position during attachment and detachment of a firearm stand.

Abstract: Embodiments herein relate to the field of firearm accessories, and, more specifically, to reusable laser sighting devices for rocket launchers and other large weapons, particularly reusable laser sighting devices that allow retrofitting of existing weapons inventory. Some embodiments include a base plate that is configured to be permanently coupled to a rocket launcher, such as the M72 LAW, and a laser module configured to removably couple to the base plate. In various embodiments, the systems disclosed herein permit a the module to be removed from the base plate of a spent rocket launcher, and coupled to the base plate of a new rocket launcher, thereby reducing waste. In various embodiments, the laser module may be factory calibrated with respect to the base plate, and therefore once the base plate has been fixed to the rocket launcher, no field calibrations of the laser module are necessary.

Abstract: A gun trigger-locking device which is configured to be manually installed on a gun with a trigger-blocking member disposed behind the trigger to prevent the gun from being fired. The device includes a data receiver, a data memory and a logic device for determining whether data received by the receiver is the same as data stored in the memory. If a data match is indicated, the logic device causes an electromagnetic device to move a locking member to an unlocked position, permitting the trigger-blocking member to be unlocked so the gun can be fired. A separate electronic key is provided to transmit unlock data to the data receiver of the trigger-locking device. This unlock data includes biologic data identifying the gun owner or some other person who is licensed or otherwise authorized to fire the gun. The trigger-locking device includes means for detecting when the device has been tampered with or removed from the gun, and transmitting an alert signal to the electronic key, for relaying to a central station.
