Abstract: Provided is a handgun recoil spring guide rod having an elongated rod body configured to fit within a compression recoil spring. An axially elongated slot is formed transversely through the body and a blocking member that is configured to fit entirely within the slot and pivotably movable between a first position entirely within the slot and a second position partially protruding from the slot, such that it engages the recoil spring to hold the spring in a more compressed condition.

Abstract: A method for forming a weapon accessory mounting device to attach to a projectile firing weapon is disclosed. A flexure for receiving a body of the weapon accessory is formed. A pivot portion is formed at a first end of the flexure to attach the flexure to the weapon at a first attachment region. A second attachment portion is formed at a second end of the flexure to attach the flexure to the weapon at a second attachment region. A first aperture is formed in the pivot portion configured to receive a pivot pin. A second aperture in the weapon accessory body receives the pivot pin at a weapon accessory body first end to attach the weapon accessory body first end to the pivot portion. The pivot portion is configured to convert at least a portion of energy of a weapon shock recoil from translational energy to rotational energy.

Abstract: A system and method for a weapon accessory mount is disclosed. The weapon accessory mount is configured to attach a weapon accessory to a rail of a weapon configured to fire a projectile in a projectile path. A flexure is configured to receive the weapon accessory. The flexure includes a first end attached to the rail at a first pivot portion, and a second end opposite the first end attached to the rail at a second portion. The first pivot portion is configured to convert at least a portion of energy of a shock recoil from the weapon from translational energy to rotational energy, the second pivot portion has a similar functionality to the first pivot portion.

Abstract: A recoil-operated, impulse averaging, air-cooled, magazine-fed, automatic weapon. An operating group of the weapon includes a chamber, a bolt, a barrel extension and one or more toggles. The recoil action of the weapon from firing a first round drives the toggles in a motion constrained by a cam way. The toggles then drive the chamber in a linear reciprocating motion ejecting a first round and over-riding the next round. An impulse averaging system controls the speed of the recoil.

Abstract: A device and method for increasing the rate of the firing cycle of a semi-automatic firearm includes a base that is adapted to support any one of a variety of semi-automatic firearms. The base includes a trigger extension with a grip, a slide mount, and a slide housed within the slide mount. At least the receiver, barrel, and trigger assembly of the firearm are secured to the base so that they may move as a single unit upon the base between a rearward position upon discharge of the firearm and a forward position. A biasing means continuously biases the receiver, barrel, and trigger assembly upon the base toward the forward position to effect successive discharges of the firearm.

Abstract: A spring device for firearms (10) and a firearm are disclosed. The spring device is used for returning a first weapon part (16) of the firearm (10) from a second position into a first position, from which it has been brought into the second position in relation to a further weapon part (11) under an actuating force, while loading the spring device. The spring device has at least one gas spring having a piston/cylinder arrangement (19), a cylinder (20) of the piston/cylinder arrangement (19) being attachable to one of the weapon parts (16; 11) and a piston rod (18) of the piston/cylinder arrangement (19) being attachable to the other of the weapon parts (11; 16).

Abstract: A contained Davis gun system enables misfire and hang-fire handling for fire out of battery (also known as soft recoil). The gun system decreases structural dynamic activity of the gun barrel during launch with resulting increases in system accuracy. The gun system further presents synergistic advantages when combined with a conventional recoil system in a double recoil design. The gun system includes a non-recoiling barrel and a recoil system engineered to contain a recoiling inertial breechblock capable of translating within the gun barrel. The recoil system includes a brake and a spring secured to a mount fixture. The breechblock enables the loading of the propellant and the projectile within the barrel, and further enables pressure to be contained within the barrel during firing. The recoil system applies a load to the breechblock, which is a function of the breechblock position and its velocity within the barrel.

Abstract: An automatic projectile firing weapon and a related method for absorbing the recoil force of an automatic projectile firing weapon are disclosed. The weapon includes a barrel assembly that is slidably mounted in a receiver, biased by an operating spring, and engageable with a main sear. A gas operated bolt assembly is slidably mounted within the barrel assembly and is driven by a bolt spring. A trigger is provided to release the main sear and allow the operating spring to move the barrel assembly forwardly in the receiver. There is further provided a buffer connected between the receiver and the barrel assembly to dampen the velocity of the barrel assembly to ensure the barrel assembly is moving at a predetermined maximum velocity when a round is fired at a predetermined firing position. The recoil energy from the fired round is absorbed mainly by the forward motion of the barrel assembly and in part by the operating spring and buffer.

Abstract: A firearm with an automatic cycle, includes a frame (1), a barrel (2) mounted on this frame (1) and at least one breech bolt (3) mounted in a movable manner in relation to the frame, whereby the barrel (2) and the breech bolt (3) can be separated so as to make it possible to feed ammunition. The barrel (2) is also movable in relation to the frame (1), both forward and backward relative to a rest position, whereby the barrel (2) and the breech bolt (3) are mounted such that the barrel (2) can recoil together with the breech bolt (3) relative the rest position and can continue, when returning forward, can continue beyond the rest position and then return to the rest position, whereby the advancing of the barrel (2) beyond or forward of the rest position takes place at least partly after the separation of the barrel (2) and the breech bolt (3).

Abstract: The present invention provides a recoil-redirecting mechanism for a gun which includes a frame, a gun barrel assembly having a barrel and a receiver with a bolt therein. The gun barrel assembly is slidably mounted to longitudinally reciprocate on the frame between a forwardmost position and a rearwardmost position. Means for firing the gun when the gun barrel assembly is substantially at its forwardmost position is provided. The recoil-redirecting mechanism includes a recoil-absorbing spring, a fixed pulley mounted on the frame, and a travelling pulley mounted on a longtudinally-reciprocating block which is longitudinally slidable relative to the frame substantially parallel to and independent from the gun barrel assembly. A cable having a first end fixed relative to the frame operably extends over and is reversed in direction by the travelling pulley, further extends over and is reversed in direction by the fixed pulley, and has a second end fixed to the gun barrel assembly.

Abstract: A grenade launcher and attachment for use on an infantry weapon, such as a rifle. The launcher fires grenades of the type which have a hollow tubular rear chamber slidably mounted on a guide rod and a piston head fitted into the bore of the chamber to seal an explosive charge therein and form an extensible explosion chamber. Locking elements for silently installing the grenade launcher without the use of complex tools are provided. Recoil buffering or compensation is provided to minimize the perceived recoil when grenades or other projectiles are launched from a shoulder held firing position. A detent is provided to secure projectiles on the guide tube until they are fired.

Abstract: A stable automatic or semi-automatic firearm having a differential recoil system in which an open bolt has a designed mass and closing velocity to impact and drive a reciprocating barrel forwardly without rebound and remain locked to the barrel during the period when there is high firing pressure in the barrel. Since the bolt supports the cartridge during the time of high pressure, the cartridge is prevented from prematurely being extracted and rupturing; and since recoil momentum is utilized in arresting and returning the bolt, stability of the firearm is improved.
