摘要： A user-adjustable recoil reduction system for a firearm includes a buttstock and a butt pad assembly movably mounted to the buttstock. A spring is disposed in the buttstock which is acted on by opposing front and rear spring guides. A preload adjustment screw is rotatably coupled to the butt pad assembly which engages the rear spring guide. Rotating the screw in opposing directions alternatingly advances or retracts the rear spring guide in the buttstock. Advancing the rear spring guide compresses the spring to set a first spring preload condition and retracting the rear spring guide relaxes the spring to set a second spring preload condition different than the first condition. The spring preload conditions may be selected to match firing light or heavy type ammunition shell loads. In one embodiment, the adjustment screw is accessible for adjusting the preload without removing the butt pad assembly from the buttstock.

摘要： A chamber reinforcement for composite firearm barrel and method for forming the same. In one embodiment, the barrel includes an inner tube defining a bore that provides a bullet path and an outer sleeve preferably made of a material lighter in weight than the tube. In some embodiments, the inner tube is made of a material that preferably has a greater density and strength than the outer sleeve. The reinforcement in one embodiment may be in the form of an end cap disposed on a portion of the sleeve. The reinforcement preferably is made of a material comparable to the inner tube in density and strength to reinforce the area where a chamber is formed for receiving a cartridge. In the preferred fabrication, the reinforcement, tube, and sleeve are forged together to provide a strong and unitary structure for withstanding combustion pressures and forces associated with discharging the firearm.

摘要： A revolver having essentially conventional cylinder (12), trigger (14), and cylinder pawl (26) is provided with a novel and positive acting cylinder latch arrangement (23, 24, 35, 36, 42) wherein the trigger (14) has a trigger pivot portion (44) formed with a transverse pivot hole (54) and with a longitudinally extending actuator receiving slot (51) through which the trigger pivot pin (22) extends, a cylinder latch actuator (42) is slidably mounted within said actuator receiving slot (51) and on said trigger pivot pin (22) for limited longitudinal and rotational movement on said pin (22) within said slot (51), and a cylinder latch (23) is pivotably mounted for rotation of the nose portion (35) thereof into and out of engagement with the cylinder latch notches (18) formed in the outer surface of the cylinder (12). Rotation of the trigger (14) from its at-rest position to its ready-to-fire position causes the cylinder latch actuator (42) to contact and depress and then to release the cylinder latch (23) thereby causing the nose portion (35) of the cylinder latch (23) to rotate out of engagement with one of the cylinder notches (18) and then to rotate into engagement with the next cylinder latch notch (18) of the cylinder (12). Rotation of the trigger (14) in the opposite direction causes the cylinder latch actuator (42) to press against the cylinder latch (23) and thereby to move the cylinder latch actuator (42) longitudinally rearwardly a sufficient distance to allow the forward end of said cylinder latch actuator (42) to clear the rearward end of said cylinder latch (23).

摘要： A composite barrel for a firearm and method for forming by forging. The barrel includes at least two materials joined together by forging. In a preferred embodiment, at least one material is preferably lighter in weight than the other material. The barrel may include an inner tube and an outer sleeve. The inner tube defines a bore that provides a bullet path and in one embodiment may be made of steel or alloys thereof. The outer sleeve surrounds the inner tube and in some embodiments may be made of aluminum, titanium, or alloys of either thereof. The tube preferably includes an exterior surface containing recessed areas therein for receiving material displaced from the outer sleeve by the forging process. The preferred barrel forming method generally may include inserting the tube into the sleeve, striking an outer surface of the sleeve, and deforming the sleeve to force material to flow into the recessed exterior surface of the tube to bond the tube and sleeve together. The method of forming may be used to produce long and short barrels for rifles and handguns respectively, and more broadly to produce other composite components unrelated to firearms.
