Abstract: Firearm bolt assemblies and firearms including the same are described. In embodiments the firearm bolt assemblies are configured to localize compressive forces applied during a transition from an initial position to a firing position to a first cam system on one side of the firearm bolt assembly, and to localize compressive forces applied during a transition from the firing position to the initial position to a second cam system another side of the firearm bolt assembly. Localizing the forces in that manner enables the use of a first cam system that is relatively robust compared to the second cam system.

Abstract: The present invention, in a non-limiting example embodiment provides a locking apparatus and method for securing locking hardware without the use of a key. In an example embodiment, the apparatus comprises at least a keyless insertion rotatable disk-style, barrel locking apparatus that, in a locked state can be inserted into a securing device without first unlocking, and then, thereafter, locking after insertion. In a nonlimiting example embodiment, unlocking and re-locking requires a key. The present invention, in an example embodiment, also provides features that allow the locking apparatus to enter and exit multiple apertures without requiring a key.

Abstract: Multi-part buffer tubes, methods of manufacturing the same, and firearms including the same are disclosed. In embodiments the multi-part buffer tube includes a cap, and a body that includes a tube. The tube may include a wall with an outward facing side, an inward facing side, a first end, and a second end. The inward facing side of the wall may define a cavity for receiving a buffer and a buffer spring for a firearm. The cap that is coupled to the body in any suitable manner For example, at least a portion of the cap may be disposed within a channel formed in the inward facing side of the tube, e.g., proximate the first end of the wall.

Abstract: Firearm safing assemblies and firearms including the same are disclosed. In embodiments firearm safing assemblies include a safing sector with a track surface and a receiver door track. The receiver door track may couple to a receiver of a rotatable firearm, wherein the receiver includes a bolt track and at least a portion of the receiver extends coaxially about a first axis. The safing sector is configured to be at least partially disposed within the receiver door track and to move between a safe position and an armed position. In the safe position the track surface is out of alignment with and does not form part of the bolt track, whereas in the armed position it is aligned with and forms part of the bolt track.

Abstract: A securing apparatus is provided for securing, in one embodiment, a plurality of enclosures, such as for example, a plurality of electric meter boxes, the apparatus being mountable to the at least one of the plurality of enclosures. The securing apparatus comprises an enclosure locking member which includes at least a bracket arm, a fastening member and a housing mountable to at least one enclosure; the securing apparatus further comprises a securing member having first and second ends, with the securing member including at least a securing bar and a coupling member being moveably attachable to the securing bar, wherein the coupling member is pivotably mateable with the extended flange of the enclosure locking member.

Abstract: An electronic locking mechanism has a body portion with movable retaining members that are controlled utilizing an electrically controlled actuator. The actuator operates the retaining member to move radially outwardly of the body portion circumference in a locked position and allows the retaining member to move radially inwardly of the circumference in an unlocked position. An electronic key can be utilized to operate the electronic locking mechanism.
