The present invention relates to one or more rust-proof springs for use in a firearm assembly. The rust-proof springs involve a variety of metals combined to create an alloy that does not react with moisture to form rust. The alloy is formed into one or more mechanical coil springs, and the mechanical coil springs are heat treated to improve the structural strength of the springs. The advantage of the rust proof springs for use in the firearm assembly is that the firearms can be exposed to moisture, such as moisture from rain, and the firearm user would not have to worry about rust on the firearm springs later causing issues with the firearm working as intended. Additionally, the one or more springs have high heat resistance properties.

When a semi-automatic rifle is live fired, it is ready to be fired again. The shooter's hands remain in the firing position, and just the trigger finger and trigger are employed. But with dry fire practice, the shooter must cycle the rifle's bolt to reset the firing pin. The shooter must move one hand from the shooting position on the rifle, the rifle's long bolt is pulled back to reset the firing pin, the rifle repositioned, a new sight picture acquired, and then the next trigger press can be accomplished. This invention replaces the rifle's bolt carrier group and provides realistic muscle memory training by duplicating the action of the trigger, the feel and the sound of the release of the firing pin, and the resetting of the trigger for additional trigger activations. The invention does not interact with the rifle's firing pin.

A pistol frame is suitable for mounting of a trigger mechanism which includes a trigger mechanism housing having a through channel. The pistol frame includes an upper frame portion defining a rear receiving space, and a rear rail block disposed in the rear receiving space and including a bottom plate, and two side plates extending upwardly the bottom plate. Each side plate has a through hole suitable for aligning with the through channel to permit extension of a trigger housing pin therethrough to thereby fix the rear rail block and the trigger mechanism housing to the upper frame portion. The bottom plate and the side plates cooperatively define at least one receiving space suitable for receiving the extensions.

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.

An auto-loading firearm having a system for switches between live fire and training modes via a selector switch mounted either on the firearm frame or on a specially designed training attachment. A multi-part transfer bar, between the trigger and sear, can be selectively connected in a live fire mode and spaced apart in a training mode. A selectively engageable trigger resetting mechanism automatically returns the trigger to its set position after firing the firearm is in training mode.

A crossbow trigger assembly with a nock sensor enabling the catch to release the crossbow string only when a nock of an arrow is properly engaging the crossbow string. The trigger assembly also contains a bypass feature for deactivating the nock sensor to cause release of the crossbow string from the catch when a user activates a release switch. The bypass feature can only be activated when retractable hooks are positioned to receive the crossbow string near the catch, thereby preventing a dry fire of the crossbow string.

A trigger mechanism for use in a crossbow comprises a housing having a first slot formed in a first side and a second slot formed in a second side opposite the first side. A trigger lever, a bowstring catch and a disarm mechanism are all moveably mounted in the housing. The catch has a first end configured to engage the trigger lever and a second end configured to retain the bowstring in a cocked position. The disarm mechanism is partially positioned in the second slot and is moveable between a fixed first position proximate the housing second slot toward a second disarm position toward the housing first slot. As the disarm mechanism moves from the first position into the second position, it engages the trigger lever causing it to move out of engagement with the catch first end allowing the user to release the bowstring using the bowstring cocking device from the trigger mechanism without having to engage the trigger.
