A rifle having a straight pull bolt assembly with a bolt handle that extends outward and downward from a bolt operation mechanism. The bolt handle rotatable a limited rotational range forward and rearwardly about a horizontal axis for operating the mechanism. The handle can be reconfigured to position its rotational range about the horizontal axis and can be attached to the mechanism at either left or right sides to provide for ambidextrous operation. Bolt heads, lower frame members with magazine wells, and barrel assemblies can be readily swapped to change ammunition. The bolt assembly can be unlocked by firing or by a thumb push button release at the backside of the mechanism. A bolt removal release mechanism is forward of the thumb pushbutton and an ejector includes a spring bias and cam follower surface to reliably eject casings.

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.

An apparatus and method for modifying a handgun to accept an optical sight comprises and modified slide mechanism adapted to include a flat recessed rear section configured to receive an adapter plate for mounting an optical sight. Various embodiments of the adapter 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.

In a method of converting a semi-automatic rifle to a single shot rifle, a production semi-automatic rifle converted to a single shot rifle includes: a) conventional rifle components, including a receiving trigger, trigger guard, barrel; b) a semi-automatic firing mechanism including a gas actuated casing ejection and bolt reset mechanism including a bolt carrier with two carrier gas key threaded receiving orifices and having no production carrier gas key and a having a dual-bored metal block gas blocking mechanism attached to the bolt carrier and positioned so as to inhibit semi-automatic operation of the semi-automatic rifle by disabling the automatic gas actuated casing ejection and automatic gas actuated bolt reset functionality. In some embodiments, a modified charge handle has an extension with two attachment orifices corresponding to the metal block gas blocking mechanism orifices and is coincidentally attached to the bolt carrier.

The disclosure relates to firearms, and more particularly to a caseless weapon for magazine, semi-automatic and automatic shot. The disclosed weapon includes: a removable adjustable front sight, a removable adjustable dioptrical sight, a forward grip, a gunstock, a magazine, a receiver cover, a cocking lever, a bolt carrier, a rod, a percussion piston, a shutter housing, a safety catch of the firing percussion, a balancing gear, a barrel, a barrel latch, a multifunctional cartridge, a conical bushing of receiver, an extractor, a receiver, a big front nut, a front swivel, a magazine latch, a magazine latch pusher, a safety latch, a safety catch, a trigger bar, a bracket of the percussion mechanism, a cocking piece, a multifunction latch lever, a stop of the multifunction latch, a lock pin splint, a latch of the ramrod, a spring of the latch of ramrod, a ramrod, a caseless ammunition.

Trigger-cycled firearms have a frame, a barrel, a bolt assembly connected to the frame in registration with the barrel and operable to reciprocate between a retracted position and a forward battery position, a trigger lever connected to the frame and operable to move between a forward rest position and a rearward actuated position, and the trigger lever operably connected to the bolt to move the bolt from the forward battery position to the retracted position and to release the bolt to the forward battery position and discharge the firearm in response to movement of the trigger lever from the forward rest position to the rearward actuated position when the bolt is in the forward position. There may be a connector bar pivotally connected to the frame and operably engaged to the bolt assembly and to the trigger lever. The connector bar may be slidably connected to the bolt assembly.

A firearm action has a receiver defining a bolt passage and having a latch engagement facility, a bolt assembly including a bolt body received in the passage and operable to reciprocate between a forward battery position and a rear open position, the bolt assembly including a bolt handle movable with respect to the body between a handle forward position and a handle rearward position, the bolt assembly including a bolt latch body having a latch element, the bolt latch body movable between a locked condition in which the latch element engages the latch engagement facility when the bolt assembly is in the forward position and the bolt handle is in the forward position to prevent reciprocation of the bolt, and an unlocked position in which the latch element is disengaged from the latch engagement facility to enable reciprocation of the bolt.
