Firearms with gas piston assemblies have a receiver defining a passage receiving a reciprocating bolt assembly, a barrel defining a barrel axis and extending from the receiver in a forward direction and defining a barrel gas aperture, a gas block connected to the barrel and defining a piston bore in communication with a gas block bore, a piston assembly having an assembly forward end operably engaged to the piston bore and an assembly rear end operably engaged to the reciprocating bolt assembly, the piston assembly having a piston closely received in the piston bore and having a piston rear end, the piston assembly including an elongated intermediate rod having an intermediate rod forward end registered with the piston rear end and an intermediate rod rear end, and the piston assembly including a rear portion registered with the intermediate rod rear end and operably connected to the reciprocating bolt assembly.
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.

Abstract
A piston, comprising a main housing (2) and a barrel slide (1), which is guided displaceably thereon and which in the cross-section comprises two lateral walls (5, 6) and a cover wall (7) in between, wherein a barrel (3) is guided on the inside of the barrel slide on the front viewed in the shooting direction, and behind that an insert piece (20) is attached, which comprises a striking pin (40) and a striker spring (45); in the barrel slide (1), a transverse wall (10) is provided, which connects the lateral walls (5, 6) and the cover wall (7) of the barrel slide (1) to each other and forms an impact base (11), and behind the transverse wall (10) an insert piece (20) is disposed, which is molded from a lightweight material and is supported in the barrel slide (1) on both sides on a longitudinal guide (15).
F41A 19/30 - Mechanical firing mechanisms having only slidably-mounted striker elements, i.e. percussion or firing pins the percussion or firing pin being movable relative to the breech-block propelled by a spring under tension in bolt-action guns
