Abstract: A rear stock for a shotgun that includes at least one tube adapted for the storage of shotgun shells. The rear stock may include a tube positioned on each side of the stock for the storage of a plurality of shotgun shells. A switch slideably mounted to the front of the stock may be moved toward one of the tubes to partially eject a portion of a shotgun shell positioned with the tube. A protrusion connected to the switch extends into a portion of the tube and movement of the switch towards a side of the stock engages the protrusion against a shell stored in the tube. The continued movement of the protrusion forces a portion of the shell against a tapered surface on an internal shoulder cause a portion of the shell to be ejected from the tube within the stock.

Abstract: A forend for a firearm that includes a sight tunnel through the forend. The forend may be adapted to actuate a tube magazine of a shotgun to insert a shell from the tube magazine into a receiver of the shotgun. The forend may include an integral heat shield to protect a shooter from heat off of the barrel of the firearm. The forend may include a rail, such as an accessory rail, such as a Picatinny rail, that permits the attachment of an accessory to the top of the forend. The sight tunnel through the forend is below the accessory rail and permits the attachment of a light accessory to light up a front sight and/or a target. The front sight may be viewed through the sight tunnel by an operator of a firearm using the forend.

Abstract: A camouflage system includes a layer of an adhesion promoter so paint will adhere to the surface of an article and a first layer of paint applied to the surface on top of the adhesion promoter. A second layer of paint of a different color is applied to a portion of the first layer of paint. The second layer of paint may be in the form of a design, symbol, brand, logo, mark, and/or name. A multi-color layer is then applied to the surface of the article over the layers of paint. The multi-color layer may be a camouflage ink pattern. A clear coat may be applied over the multi-color layer. The multi-color layer affects the visual appearance of the second layer of paint. The second layer of paint may be visible at one viewing angle and may be less visible or non-visible at a different viewing angle.

Abstract: A dynamic latch to selectively retain a magazine within the magazine port of a long gun. The dynamic latch permits the magazine to be inserted into the magazine port by movement in a single direction eliminating the need to rotate the magazine in order to secure it within the magazine port. The dynamic latch may include an outer housing, a piston positioned within the housing, and a spring positioned between the outer housing and the piston. A latch profile on the end of the piston may extend out of an opening in the end of a magazine well when the spring is in an uncompressed state.

Abstract: A forearm stock for a shotgun includes a forearm stock main body, an integral shot shell carrier tube, disposed in the main body, an accessory rail, at the forward end of the main body, and a removable cover, adapted to cover the accessory rail. The forearm stock main body has a forward end, a back end, a contour, and an upper cavity for receiving a shotgun's tube magazine. The shot shell carrier tube is disposed below the upper cavity, and is adapted to receive a plurality of shot shells, with an opening toward the back end. A mechanism for urging the shot shells out of the carrier tube through the opening is provided, and a retention mechanism is adapted to selectively retain the shot shells in the carrier tube. The removable cover has a contour that substantially complements a contour of the main body.

Abstract: A dynamic latch to selectively retain a magazine within the magazine port of a long gun. The dynamic latch permits the magazine to be inserted into the magazine port by movement in a single direction eliminating the need to rotate the magazine in order to secure it within the magazine port. The dynamic latch may also eliminate the need to add a magazine well to the receiver of a shotgun or long gun. The dynamic latch may include an outer housing, a piston positioned within the housing, and a spring positioned within the piston. A latch profile on the end of the piston may extend out of an opening in the end of the housing when the spring is in an uncompressed state. The dynamic latch may also be used to connect a tube, such as a magazine tube, to the receiver.

Abstract: A shotgun forearm-stock shot shell carrier, for storing multiples of shotgun shells and quickly releasing the same for hand loading into a shotgun magazine or chamber. Improved efficiency and speed of loading shotgun shells may be achieved by a shotgun forearm-stock shot shell carrier, which may comprise one or multiple spring-and-follower-tensioned carrier cavities, integrated into a forearm stock having, in one embodiment, a spring steel shell retainer, such that shot shells inserted into a carrier are securely stacked end-to-end and held until the retainer is physically displaced. In one embodiment, manually displacing a thumb tab, such that it is relieved of providing counter pressure to the spring-and-follower assembly, allows the spring-and-follower assembly to force shot shells out of a carrier's cavity for loading into a shotgun or evacuating the carrier.

Abstract: A barrel insert is disclosed. A firearm may use a target barrel or another barrel, such as a standard barrel. The stock of a firearm may have a barrel receptacle that is shaped to hold a larger barrel. The larger barrel may be untapered. The barrel insert may be used to adapt a barrel receptacle to fit a smaller barrel. The smaller barrel may be tapered. The barrel insert may have a texture that substantially matches a texture of the firearm.

Abstract: A firearm lock that is inserted through the magazine port of a suitable firearm. The firearm lock extends from the magazine port into the bolt compartment of the firearm. The lock blocks the firearm bolt from returning from a retracted position, which may prevent the firearm from being disassembled, preventing circumvention of the lock. The lock may have a projection that can be moved into the magazine release mechanism recess to secure the lock in place. The firearm lock may be unlocked by hand or may require a key or a combination.

Abstract: A monopod for a firearm is disclosed. The monopod has a body and a leg that can extend from the body. The monopod may fit into a pistol grip of a firearm, such as a rifle. Once installed, the leg of the monopod may be extended from the pistol grip of the firearm and secured by a pin. When the leg is retracted into the body, the leg is kept in place by the pin, which opposes a force provided by a constant force spring. The monopod may be used by a user to stabilize the firearm on a surface.

Abstract: A mounting rail for a firearm is disclosed. The mounting rail may be a picatinny rail, a weaver rail, or the like, which allows tools such as lights or lasers to be attached to a firearm. The mounting rail is reversible and may be mounted within a portion of the firearm, such as the forend. The other side of the rail may match the finish and texture of the firearm so that the mounting rail is hidden from view when reversed.
