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.

A rifle includes a magazine well, a barrel detachably coupled to the magazine well, and a suppressor detachably coupled to the barrel. The barrel includes a forward barrel portion on an end of the barrel opposite the magazine well. The forward barrel portion includes a muzzle locking mechanism. The suppressor is configured to be retractable.

A gun-type firing device using a caseless projectile is disclosed. The caseless projectile has a bullet head and an impact seat at two ends thereof and a groove adjacent to the impact seat. The gun-type firing device includes a gunstock, a gun bolt and a gun barrel. The gun bolt is located on one side of the gunstock. The gun bolt includes a cocking handle and an extractor. The cocking handle can perform a linear displacement movement along the extension direction of the gunstock. The extractor is located at one end of the cocking handle. The gun barrel is located on the gunstock and is adjacent to one end of the gun bolt. The gun barrel does not have rifling.

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.

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.

Firearms, and components of firearms, improve shooting accuracy and tolerance to debris/elements that may enter the receiver during use of the firearm in the field. The outer surface of the barrel and the receiver inner surface, and/or the bolt lugs and the receiver inner surface may feature tight-tolerance or press-fit mating, to enhance axial alignment for shooting accuracy. The bolt lugs may be configured to provide said tight-tolerance mating with the receiver when in the loaded and locked position, but may also be configured to provide space for accommodating debris/elements that enter the firearm so that bolt movement is not hindered by the debris/elements, and operation of the bolt, including cycling of the bolt in the firearm action when the shooter goes to load the next round, is smooth and consistent.

A bolt-action conversion device includes a slide clamp having a longitudinal cavity, a first pin hole, and a receiver in a direction orthogonal to the longitudinal cavity and substantially adjacent to a forward end of the slide clamp. The device also includes a locking plate having a second pin hole. A body portion of the locking plate has a narrow dimension and a broad dimension relative to the narrow dimension. When the locking plate is inserted into the receiver of the slide clamp with the first pin hole and the second pin hole aligned, an opening is formed between an upper surface of the locking plate and an internal surface of the longitudinal internal cavity. The longitudinal cavity accepts a slide of a firearm such that the opening is aligned with the barrel and at least a portion of the locking plate is aligned with a frame.

Components of a firearm having a bolt with locking lugs improve shooting accuracy, due to increased coaxial alignment between the bolt, the cartridge, the receiver, and/or the barrel of a firearm. The receiver inner surface is shaped for lug-cleaning and for close tolerance/mating with the lugs only in the locked position and also with a non-threaded, axial surface of the barrel. Thus, the mating surfaces that are instrumental and/or that mainly control coaxial alignment of the receiver, bolt, and barrel are located between the lug stops and the threaded end of the receiver. The lugs may be axially curved or otherwise axially non-linear to tolerate dirt and other debris in a field environment.
