Disclosed is an extraction press assembly for facilitating removal of an object from a bore of a structure. The extraction press assembly comprises a coupling mount, a base plate, a support structure, and a press. The coupling mount can be configured to couple to the structure, thus securing the extraction press assembly to the structure. The base plate can be axially spaced from the coupling mount, and can support the press. The support structure can comprise axial extensions coupling the coupling mount to the base plate, and facilitating adjustment of the base plate (and thus the press) relative to the coupling mount. The press can be located between the coupling mount and the base plate and can be configured to expand and contract axially, and to exert a pressing force upon an extraction pole of an extraction pole assembly within the bore, which force is transferred to the object lodged within the bore. The press can be pivotally coupled to the base plate to rotate between a first position for extracting an object and a second position for accessing the bore.

A method of controlling the release of bullets from a firearm by user behavior, including monitoring the spatial orientation of a virtual vector representing the orientation of a barrel of the firearm by receiving measurements from sensors installed in or on the firearm, engaging a trigger of the firearm to release a first bullet to a first direction, while the trigger is engaged continuously analyzing the measurements to identify preconfigured motion patterns, releasing bullets automatically responsive to identifying the preconfigured motion patterns, wherein the preconfigured motion patterns include identifying that the user is stabilizing the firearm toward a target that is in a direction that is distinct from the first direction.

Methods and apparatus are described for extracting and storing electrical energy from the gaseous discharge of a firearm. In one embodiment a muzzle device is provided comprising of at least one thermoelectric generator which generates electric power, to be stored in a battery, using heat transferred from the gaseous discharge of a firearm to the thermoelectric generator by a heat sink.

In some examples, a guide rod can include: a first shaft that includes a first aperture at a first end, a second shaft positioned within the aperture of the first shaft, a sleeve with a second aperture through an interior portion of the sleeve to receive the first shaft, and a gear mechanism positioned within the first aperture to interact with the second shaft and the sleeve when the sleeve changes position along the first shaft.

The inventive technology comprises a novel gun barrel thermal indicator system that incorporates one or more thermogenic compounds that may be coupled to a gun barrel and indicate the temperature of a gun barrel during and after use. Additional embodiments may comprise a digital gun barrel thermal indicator system that may be coupled to a gun barrel and digitally indicate the temperature of a gun barrel during and after use. This novel gun barrel thermal indicator system may indicate the temperature at which the gun barrel will cause burns, is unsafe to store, or if a pre-determined threshold temperature has been reached resulting in a loss of firing accuracy, as well as imminent and/or actual barrel failure.

A gun cleaning apparatus includes a cleaning tool and a storage case. The cleaning tool has a cleaning section and a pull cord having a distal end for pulling the cleaning section through a gun barrel. The storage case is configured for enclosing the cleaning tool. The storage case includes a substantially hollow container defining a rim at opening thereof, and a removable lid positionable between a closed configuration and an open position. The removable lid includes a handle section for gripping by a user to assist with pulling the cleaning tool through the gun barrel in the open configuration and configured to engage the rim in the closed configuration, and a connection section extending from the handle section, the connection section defining an elongate slot and a cavity for securing the distal end of the pull cord therein.

A firearm having a laser induced friction surface. A method for forming the laser induced friction surface on the firearm may includes the steps of disposing the laser machine adjacent to a component of the firearm, adjusting the laser machine, then applying the laser beam of the laser machine onto a component surface.
