Abstract: A shooting rest for different weapons provides ends that are offset from the central portion of the rest to provide a space that accommodates a portion of the weapon being used with the rest. The shooting rest can be used with one or two supports that engage the weapon being used with the rest. Each support can be rotationally adjusted about a vertical axis and tilted about a horizontal axis. Each support can be tilted inwardly to a storage position for storage and transport of the rest. When in use, the entire rest can be tilted about its main support. A support assembly includes an adjustable arm that carries the shooting rest from the top of a monopod that is anchored to allow repositionable use without interference with the hunter's legs.

Abstract: A method of firing a firearm includes compressing a main spring to rotate a latch pin lever; forcing a latch pin forward by the latch pin lever to force a cylinder forward toward a barrel; sealing or substantially sealing the barrel and the cylinder; and releasing a hammer to strike a cartridge while the barrel and the cylinder are sealed.

Abstract: A bumper for preventing a forward portion of an electrode from penetrating a target comprises a rearward portion and an expandable portion. The rearward portion is configured to couple the bumper to a forward portion of an electrode. The expandable portion may comprise a plurality of members. The expandable portion is configured to transition from a collapsed state to an expanded state after being launched toward a target. The expanded state comprises a greater contact area than the contact area of the collapsed state. The greater contact area of the expanded state is configured to distribute a force of impact on the target to prevent penetration into the target. The transition from the collapsed state to the expanded state may be configured to increase a duration of impact with the target, thereby reducing a force of impact on the target to prevent penetration into the target.

Abstract: Systems, apparatuses, and methods are described which provide a camera mount system. The camera mount system can include, for example, a first optical element and a second optical element. Incoming light from a scope on a weapon, for example, is partially transmitted and partially reflected by the first optical element. The partially transmitted light passes through an eyepiece to a viewer (e.g., a shooter). The partially reflected light is reflected by the second optical element and is recorded by a recording device (e.g., a camera, a video recorder, an image sensor, etc.). The viewer has direct access to the scope optics, a spotting scope, or binoculars, for example, and the camera and the viewer have access to the same view.

Abstract: A device for converting a semiautomatic firearm to a non-semiautomatic firearm. The device includes a bolt stop lever pivotally attachable to a receiver of a firearm, a spring configured to be installed in contact with the bolt stop lever and a firearm receiver such that the spring exerts a force on the bolt stop lever to retain the bolt stop lever in a first position, and, a bolt release mechanism operatively coupleable to the bolt stop lever and configured to pivot the bolt stop lever against the force of the spring into a second position. The bolt release mechanism is operatively decoupled from the bolt stop lever when the bolt stop lever reaches the second position. When in the first position the bolt stop lever restricts motion of a bolt of the firearm, and when in the second position, the bolt stop lever permits motion of the firearm bolt.

Abstract: A socket driver for a perforating gun assembly. The socket driver includes a first end, and a second end opposite the first end.

The socket driver is configured to mate with a shoulder along the tandem sub of the perforating gun assembly. Specifically, the socket driver includes a radial notched profile. The notched profile is configured to mate with a radial pattern of slots along the shoulder of the tandem sub. In one aspect, the socket driver is between 3 and 8 inches in length. In one aspect, the first end of the socket driver comprises an opening configured to receive a torque tool. A method of connecting ends of perforating guns using the socket driver is also provided herein.

Abstract: This invention relates to a non-detonating cartridge containing an explosive composition, and more particularly but not exclusively to a non-detonating cartridge having enhanced safety characteristics. The cartridge includes a container including a cavity suitable for receiving a low explosive composition; an initiator, for in use initiating the explosive composition inside the cavity; and a shielding member which is displaceable relative to the container between a safe position, in which the initiator is shielded from the cavity such that initiation of the initiator does not result in initiation of the explosive composition, and a live position in which the initiator is exposed to the cavity to permit initiation of the explosive composition. The cartridge is characterised in that the shielding member is slideably displaceable relative to the container.
