Abstract: A trigger mechanism that, in various examples, may be configured to pivot or rotate in multiple directions, enabling actuation along multiple axes or planes of motion consistent with natural finger movement. For instance, a trigger may be supported or otherwise connected to a host device—such as a firearm, tool, or other manually actuated mechanism—in a manner that permits movement in multiple directions or rotation about multiple axes, allowing the trigger pull to follow the natural motion path of a user's finger. In some examples, the trigger mechanism may actuate when the trigger reaches one or more defined actuation points or when a threshold level of force is applied—regardless of the trigger's motion path. In this way, the trigger mechanisms of the present disclosure may accommodate the unique trigger pull motions of different users, regardless of hand position, technique, or training level.

The shield body comprises a shield panel provided with an edging, the shield panel having a first and second face defining a threat side in a threat direction and a protected side in a protected direction opposite the threat side and threat direction, respectively and having opposite panel edges, the edging covering at least part of the panel edges. The edging of the shield body comprises connectors operably connected with each other. The first and second accessories are operably connectable or connected with each other via the connectors for power and/or a signal transfer from the first accessory to the second accessory and/or back via the connectors.

Abstract: A muzzle brake having a tuner and allowing for micro-adjustments to the weight of the barrel of a firearm. Upon being fired, the weighted the barrel mitigates the effect on aiming by disruptive frequencies reverberating through the firearm. The muzzle brake can incorporate a muzzle brake and be positioned after the muzzle brake segment such that the harmonics of the muzzle brake segment can also be affected by the muzzle brake. Use of the tuner on a firearm can increase overall accuracy and affect the groupings of shots on target when compared to use of a firearm without a muzzle brake.

Abstract: A ballistic garage door assembly and a kit for converting a standard garage door includes metal shell panels formed from coil stock metal that uses sheets of ballistic material secured to each metal shell panel. Joint inserts applied to the horizontal ends of the garage door panels provide bullet resistant characteristics at the joints. Ballistic sheets of compressed multiple plies of ballistic material, hardened ballistic resin, or bullet resistant metal barriers, are applied to each garage door shell. Increased levels of ballistic protection will utilize thicker ballistic sheets and increased thickness of the walls of the joint inserts, and optionally an additional external ballistic bumper to increase ballistic performance of the joints between the garage door panels. The outward aesthetic appearance of the garage door does not change appreciably.
