A trigger mechanism has a top sear for engaging a cocking piece, a transfer arm for engaging the top sear, and a safety lever and second stage sear which engages the transfer arm. The safety lever prevents unintentional firing of a firearm with the trigger mechanism. A bottom sear cooperates with the safety lever and the second stage sear. A single stage operation involves both a first stage spring and second stage spring upon trigger load application. In a two-stage operation, the first stage spring is engaged and then the second stage spring is also engaged. A selector pin provides flexibility to alter the mode of operation of the trigger mechanism between single stage trigger operation and a double stage trigger operation.

An interchangeable barrel assembly for a firearm including a novel barrel and tool assembly which are used with a receiver having an open aft end. The tool assembly is configured to be inserted into the receiver open aft end so as to engage the aft end of the barrel. Torque applied to the tool assembly thereby transfers torque to the barrel without transferring forces to the action. This enables the same action to be used with different barrels and the barrel may be removed without removing the receiver or other components of the modular chassis or accessories mounted thereon. Additionally, standard torque may be applied to the barrel for connection to the receiver and firearm precision is maintained.

An adjustable headgear mount device and system is presented. The mount system comprises an adjustable jaw that is adjustable by the user to accommodate a various range of male dovetail parts. A dovetail adapter and the adjustable jaw define a female receiver cavity configured to engage a male dovetail protrusion therein. A user moves the adjustable jaw into a desired position relative to the dovetail adapter and securedly fixes the adjustable jaw in the desired position with at least one attachment screw. In the desired position, a portion of the device engages the male protrusion. The adjustable jaw can be moved to a different position by the user if a different size male dovetail part is desired to be attached to the headgear.

An adjustable headgear mount device and system is presented. The mount system comprises an adjustable locking catch that is adjustable by the user to accommodate a various range of male bayonet parts. A receiver element defines a slot that the adjustable locking catch is positioned in. The user can slide the catch into a desired position in the slot and securedly fix the catch in the desired position with at least one set screw. In the desired position, the catch can engage a portion of the male bayonet. The catch can be moved to a different position by the user if a different size male bayonet part is desired to be attached to the headgear.

A trigger mechanism for a firearm is presented. The trigger mechanism has a trigger housing, a sear, a sear block and a trigger lever. Actuation of the trigger causes the trigger lever to rotate and eventually come into contact and move the sear block, which permits the sear to fall and permits the actuation of the firing mechanism. The trigger lever may be pivotally secured to the housing at a first pivot and the sear block is pivotally secured to the housing at a second pivot. The first and second pivots may be spaced apart from each other or coincident.
