Trigger armor systems and grip armor systems are provided. The trigger armor system may include an integral finger rest, grip, and knuckle guard. The grip armor system may include an integral angle grip and well grip. Trigger and grip armor systems including an integral trigger armor system and grip armor system are also provided.

A semiautomatic shotgun comprising a receiver, a barrel, a forward gas block assembly attached to the barrel, a slider assembly rearward of the gas block assembly extending into the receiver. Upon firing a shotshell the explosive gases in the barrel are diverted through two ports into the gas block assembly, specifically into a pair of lateral pressure relief valves positioned on both sides of the barrel. The pressure relief valves further having a gas pathway to a piston chamber. A piston is forced rearwardly and engages a slider of the slider assembly that is linked to a breech block in the receiver. The breech block loads unfired shells and ejects the fired shells accomplishing the semiautomatic recycling. The dual pressure relief valves actuate to moderate and limit the gas pressure that enters the piston chamber when using shotshells of different power levels thereby providing consistency in the recycling operation.

Weapon with an integrated winch (integrated winch) includes a reel, a tightening bolt and a line. One end of the line is attached to the reel and the other end of the line is preferably terminated with a line loop. A line O-ring is retained by the line loop. The tightening bolt may be inserted through a riser hole, threaded into a riser or threaded into stabilizer or the like. The tightening bolt is inserted through an axle hole in the reel. Tightening a head of the tightening bolt head prevents the reel from rotating. The line is prevented from unraveling by securing the line O-ring to the reel. A second embodiment of the integrated winch preferably includes the reel, a bracket, a reel axle, a riser bolt and two thumb nuts. The reel is rotatably retained by the bracket and the bracket is retained in a riser.

An improved firearm system is provided. The improved firearm system comprises an improved firearm cartridge for use in firearm designed to fire the improved firearm cartridge. The firearm cartridge comprises a projectile substantially seated within a cartridge casing, which reduces the length of the firearm cartridge. The cartridge casing may be modified to accept more than one primer. A firing pin of the firearm may be modified so it may strike each of the primers of the cartridge casing. A bolt body may be modified so that it has two pieces connected by a pin so that it may house the modified firing pin. Because the length of the firearm cartridge is reduced, the length of a magazine that holds firearm cartridges may also be reduced. This allows a handle of the firearm to be moved forward so that the magazine may be inserted through the handle.

The invention relates to a rifle comprising a barrel, a stock, a bipod and bipod housing formed within the stock of the rifle and in which one or more legs of the bipod may be housed when the bipod is in a storage position. The forestock may comprise a body and a tip. The tip may be configured to support one or more legs of the bipod and may also be configured to hinge away from the body to cause the legs to project toward a supporting surface when the bipod is in an operational position.

Firearms and barrel assemblies are provided herein that include a barrel assembly having a barrel having a proximal end and a distal end comprising a muzzle. The barrel also includes a chamber defined in the proximal end. The chamber includes a distal end and a proximal end. A bore extends distally from the distal end of the chamber. The bore defines a central axis of the barrel assembly. The barrel assembly also includes a barrel extension extending from the proximal end of the barrel. The barrel extension has a distal end and a proximal end. The barrel extension defines a bolt receiving recess in communication with the chamber. The barrel extension further has a barrel vent channel defined therein in communication with the bolt receiving recess. The barrel vent channel is defined in the barrel extension in a direction that is transverse to the central axis of the barrel assembly.
