A rifle stock has a frame, a body having a butt pad connected to the frame and operable to move within a range of length of pull positions, the frame defining a plurality of pockets, each associated with a different length of pull position, the body defining a latch passage, a latch having a nose, the latch received in the latch passage and movable between a retracted position in which the nose is clear of the pockets and movement of the body is enabled for adjusting, and an extended position in which the nose is received in a selected one of the pockets, a release lever pivotally connected to the frame and operably connected to the latch, and the release lever movable between an operating position in which the latch is in the extended position, and an adjustment position in which the latch is in the retracted position.
A bolt action firearm has a frame defining a bolt passage, an elongated bolt assembly configured to reciprocate within the bolt passage, the elongated bolt assembly defining a firing pin passage, a firing pin assembly received in the firing pin passage, a bolt handle having an inner end configured to removably engage the firing pin assembly and an opposed free end, the bolt handle inner end having opposed spaced-apart prongs defining a bolt handle channel, the bolt handle defining a pocket associated with the bolt handle channel, the firing pin assembly having a handle engagement portion having a first section configured to be received in the bolt handle channel, and the firing pin assembly having a second section adjacent to the first section such that when the second section is biased into the pocket, the firing pin assembly is secured against passage through the bolt handle channel.
F41A 3/22 - Rigid bolt locks, i.e. having locking elements rigidly mounted on the bolt or bolt handle and on the barrel or breech-housing respectively the locking elements effecting a rotary movement about the barrel axis, e.g. rotating cylinder bolt locks hand-operated the locking being effected by rotating the operating handle or lever transversely to the barrel axis
Caracal International L.L.C. (United Arab Emirates)
A handgun and a locking device for a handgun are disclosed, which handgun includes a housing, a magazine-receiving space in the housing, a slide movable in the housing, and a trigger mechanism; the locking device includes a locking body to be inserted in the magazine-receiving space, the locking body at least partially being shaped like a magazine and including a releasable catch engaging in the magazine-receiving space when the locking body is in its inserted state, and cooperating with an eccentric provided in the locking body.
A pistol includes of a pistol body, a slide and a trigger mechanism which includes: a firing bolt, a horizontal control ramp in the slide, a guide coulisse and a guide finger cooperating with the former, a control spring fastened in the pistol body and deflectable in transverse direction, and a trigger bar hinged to a trigger and cooperating with the control ramp, the guide coulisse and the control spring, the trigger bar having a catch nose retaining the firing bolt lug. To achieve enhanced smooth-running and reproducible precision with a minimum of production costs, the control spring has a disc in its upper end region, the contour of said disc being round in the plane of the trigger bar, and the trigger bar has a substantially vertical catch nose in its rear end region and an oblique rear edge cooperating with said disc.
A magazine for improved stacking capacity includes a housing, a front wall connected to a back wall by sidewalls, a base, a spring adapted to be received inside a recess in the base in order to reduce the space occupied by the spring. The spring having various spiral sections wherein the spiral section having different lengths so that the spiral sections fit into each other when the spring is compressed against cartridges in order to enable stacking of additional cartridges.
For a pistol having a hollow pistol grip in which a magazine for rounds which is insertable from below is held, a magazine catch is provided which is realeasable from either side, offers a maximum of safety, is user friendly and has relatively few parts. The magazine has a lug on its front wall; in the front part of the pistol grip a sliding block is arranged so as to be displaceable in transverse direction, which is held in its middle position by at least one spring, in which position the lug rests on the sliding block. The sliding block has a vertical groove on either side of the lug, which can be brought into the path of movement of the lug during insertion of the magazine by displacement of the sliding block in either one of the two directions.
A pistol with a firing pin includes a firing pin safety provided in the breech part. To afford a firing pin safety that is as simple and operationally safe as possible, a resilient tongue attached on an external side face of the breech part is provided, which resilient tongue forms a hook extending into the interior of the breech part, which hook comes to lie in front of a shoulder provided on the striker when the latter is in its cocked position, and the resilient tongue has a downwardly projecting web which cooperates with the trigger arm. The resilient tongue is integrally formed with an ejector spring.
