A method of assembling a bolt handle to a bolt assembly of a firearm includes inserting the bolt handle through a handle opening defined by a bolt body. A distal end of the bolt handle is inserted through the handle opening until the distal end extends past an outer perimeter of the bolt body. At least a portion of a bolt shroud is inserted through a first portion of an aperture defined by the bolt handle. A force is applied to the bolt shroud while the bolt handle is retracted within the handle opening of the bolt body so that the bolt shroud is positioned within a second portion of the aperture. The bolt shroud is held in connection with the bolt handle when the bolt shroud is positioned within the second portion of the aperture to secure the bolt handle to the bolt body.

An apparatus and method for modifying a handgun to accept an optical sight comprises a modified slide mechanism adapted to include a flat recessed rear section configured to receive an adapter plate for mounting an optical sight. Various embodiments include modified internal components used to replace stock components what will no longer fit within the modified profile of the slide mechanism. Replacement of the slide mechanism and associated internal components will allow a user to add an optical sight to an existing handgun.

A compact action for a firearm including an upper receiver housing incorporating a barrel. A bolt and supporting carrier is positioned within the receiver housing so that the bolt is engaged to a rear receiver end of the barrel in a cartridge chambering position. Guide rods are supported within the housing above the barrel and extend in parallel to a rear located end plate. The carrier includes a carrier key supported by and displaceable along the guide rods between the barrel and a rearward bumper component. A gas tube extends from a forward located gas block overlaying a gas discharge aperture in the barrel to a gas key for actuating the carrier rearwardly following discharge of a ballistic from the barrel. A charging handle is manually displaceable along a slot in the housing for actuating an interior slider component, in turn actuating the carrier key to cycle the carrier and bolt.

A bolt-action weapon includes a receiver rotatable about a longitudinal axis, a first gear component, a second gear component and a bolt-action lever. At its front end, the receiver has a non-rotating bolt head. The first gear component is attached to the rear end of the receiver in a rotationally fixed manner, wherein the receiver rotates with the first gear component when the latter rotates. The second gear component lies at an angle to the first gear component and is in engagement with the latter for mechanical transmission of a rotational movement. The bolt-action lever is connected to the second gear component such that the bolt-action lever can rotate with it, whereby the bolt-action lever can be engaged in at least two functional positions. The bolt-action lever is movable back and forth in axial direction together with the two gear components and the receiver.

A fixed ejector is attached to the upper receiver, in combination with machining a slot into the carrier and the bolt, such that the ejector remains static such that, upon the bolt cycling, the spent shell casing contacts the ejector, causing it to be ejected out of the upper receiver.

A breech for a straight-pull repeater rifle, comprising a breech box and a locking sleeve guided therein as well as a locking bar guided in the breech box and connected to the locking sleeve, the locking bar connects a bolt head to a bolt handle with a interposition of a chain link, wherein the chain link is linked in an articulated manner to the locking bar and the bolt handle, and the bolt handle can be swivelled between an open position and a closed position of the breech and interacts with a firing pin nut connected to a firing pin. A bolt head inserted into a breech sleeve at an end of the breech facing away from the bolt handle is provided. The locking sleeve and the locking bar are a one-part locking sleeve-bar and a locking spring pushing the chain link in the direction of its closed position is provided.
