Systems, devices, apparatus and methods for providing a semi-automatic rifle with ammunition magazine, having a docking port/station for allowing a semi-automatic pistol to be inserted. The trigger on the pistol can be used to fire the rifle and use the rifle ammunition. When the rifle ammunition is depleted, the pistol can be removed and separately fired using its' own ammunition.

A universal mounting device for a pistol having a rear extended connecting extension, wherein the universal mounting device includes a buttstock body having an elongated holding channel for slidably receiving the connecting extension therealong, and a locking mechanism provided at the buttstock body to selectively adjust a diameter size of the holding channel. The locking mechanism is actuated to reduce the diameter size of the holding channel for tightly pressing an inner wall of the holding channel at an outer wall of the connecting extension so as to lock up the connecting extension at the holding channel.

A bedding block for mounting a barreled action for a rifle to a stock can include an elongated body configured to receive the barreled action for the rifle in a semicircular channel defined in top surface of the elongated body. The semicircular channel can have a first radius, the barreled action can have a second radius, and the first radius can be less than the second radius.

An RF antenna platform selectively configurable for portable or non-portable use, the platform comprising: a body comprising at least one RF antenna for transmitting and receiving RF signals; at least one component interface provided on the body for interchangeable mounting of different types of stabilising component to the body; wherein the component interface is common to each of the different types of stabilising component such that the portable and non-portable configurations of the platform are selectively determined by the type of stabilising component mounted to the body.

A firearm recoil pad assembly includes a base plate, a pad plate, and a pad, and can be secured to the buttstock of a firearm. The base plate has a bore formed therethrough, and the pad plate has a bore formed therethrough. A bolt extends through the bores in the base plate and the pad plate and couples with a nut to secure the pad plate to the base plate. The pad is affixed to the pad plate and includes a rear face formed with compression channels extending across the rear face, and opposed left and right sides. The rear face of the pad is canted toward one of the left and right sides.

In some embodiments, a crossbow comprises a stock, a fire control assembly and a bow portion. In some embodiments, the bow portion comprises a prod, a first limb, a second limb, a first rotatable member and a second rotatable member. The crossbow comprises a drawn orientation wherein the first rotatable member overlaps with the stock. In some embodiments, a reference line oriented orthogonal to a shooting axis intersects the stock and the first rotatable member. In some embodiments, the reference line is parallel to a rotation axis of the first rotatable member.

An adjustable shoulder rest for a rear stock for a rifle or shotgun, with slidable adjustment features at the butt plate to customize the shoulder to firearm interface, providing diverse adjustment options pursuant to user preference and/or circumstances of use. The present invention further provides a pivotal, slidably-adjustable shoulder rest to facilitate customized position adjustment to the firearms orientation vis-a-vis the operator, including the option to provide a swivel connection for adjustment of the firearm during operation as well as the option of providing haptic feedback to communicate to the user or otherwise facilitate line of sight alignment of the firearm at various angles relative to the longitudinal axis thereof in line with one or more sighting apparatus mounted thereto.

Handguard anchoring systems suitable for attaching a handguard to a firearm are disclosed, including systems having a fastener that extends into a barrel nut and compresses at least a portion of the handguard between the fastener and the barrel nut. Many embodiments include openings in the handguard and/or a plate that are oversized for the fastener such that the handguard may be rotated relative to the barrel nut when a portion of the fastener is positioned within the opening.

Devices and method for converting collapsible firearm stocks are provided. In one embodiment, a conversion device for converting a stock is provided, the stock comprising a locking pin, configured to slide along a receiver extension having a plurality of position holes and lock into position, the conversion device comprising: a first insert having a first plug configured to insert into a first position hole of the plurality of position holes; a second insert having a second plug configured to insert into a second position hole of the plurality of position holes; wherein inserting the first and second plugs into the first and second position holes, respectively, covers all of the plurality of position holes except for a single position hole for receiving the locking pin of the stock; and wherein the single position hole converts the stock from being collapsible to fixed on the firearm.
