Abstract: An improved bolt and bolt carrier with integral gas key having an extension nozzle threadedly secured and pinned to the gas key for use with a direct gas operated firearm is provided. The extension nozzle is designed to receive a portion of the host firearms gas operating system. The firing pin retaining pin is oriented so as to expose its widest profile to the firing pins annular flange, increasing its service life. The bolt has a plurality of lugs extending from its forward end and an extractor recess. The extractor recess is constructed to accommodate an enlarged extractor claw while not undercutting the bolt lugs adjacent thereto. The extractor engages approximately 57% more of a seated ammunition cartridges rim as compared to some prior art AR15/M16 type extractors used with automatic firearms chambered in 6.8SPC. The result is an improved bolt and bolt carrier which provides for increased operational reliability.

Abstract: A rotatable buttstock mount can include a tube, a boss, a support frame including a rearward ring and a guide pin in a guide slot such that the support frame can rotate relative to the tube. When a buttstock is secured to the mount, the buttstock can rotate with the frame and thereby change the axial angle of the buttstock relative to the weapon to which the mount is secured, thereby providing a user with a variety of angular orientations of the buttstock for different shooting configurations. The mount can rotate freely relative to the tube, being actuated simply by overcoming a friction interface between components and/or a detent between the components. Thus, actuation of the mount and rotation of the buttstock to a custom angular position can be easily and quickly implemented to obtain a selected configuration for the user.

More specifically, but not exclusively, disclosed are detonation control systems and methods, which include a detonation controller unit, a safety pin configured to engage with a safety pin holder of the detonation unit, and a remote controller unit configured to receive the safety pin, wherein, only when the safety pin is removed from the detonation controller unit and engaged with a remote controller unit, the remote controller unit is paired with the detonation controller unit and capable of communicating therewith.

Abstract: A firearm activation and monitoring system which tracks, monitors, and automatically prevents a firearm from firing when a user is not in a suitable state of mind or is not an authorized user, as well as a method for activating and monitoring a firearm. The firearm activation and monitoring system generally comprises a firearm having a trigger and grip area, a plurality of biometric sensors located on the grip area which measure biometric data of a user, a trigger interlock, and a main microcontroller. The trigger interlock prevents the trigger from firing the firearm when the trigger interlock is in its normal or default position. To unlock the trigger, the user holds the grip area to activate the biometric sensors, and if the user is in an acceptable mental state, the main microcontroller will send an electrical signal to the trigger interlock, which unlocks the trigger and allows the user to pull the trigger of the firearm.

Abstract: The present folding stock adapter can be used with many types of military-type assault rifles that typically comprise a receiver extension, buffer and action spring. The present folding stock adapter can be used to add a folding capability to a standard stock allowing it to fold against a rifle's receiver when the weapon is not in use, thus reducing the overall length of the weapon. This reduction in length can facilitate its maneuverability, storage and transport in cramped quarters. The present device can also allow for the quick unfolding of the stock in order to allow the weapon to function and be fire normally.

Abstract: A double firing mode semi-automatic handgun has a frame, a barrel, a spring biased slide, and a firing assembly with a firing rod operated by a trigger. A frame pocket is provided in a rear part of the frame which is open from above, in which an associated frame inset or an associated other frame inset can be inserted. A rear part of the slide has a slide pocket in which an associated slide inset or an associated other slide inset can be inserted. A firing pin is arranged in front of the connection site of the frame pocket and behind the barrel extending to a cartridge receiving chamber. A rearward motion of the firing rod causes a surface to be pushed on the frame inset and transforms into an axial hit on the firing pin by a spring bias or by the release of a lock.
