Abstract: A mount for mounting a firearm sound suppressor or silencer to a firearm muzzle or muzzle device operates by using primary mounting lugs on the suppressor which engage sockets on the muzzle device. The primary lugs prevent the suppressor from axially moving with respect to the muzzle device, thus causing them to be fixed together as a unitary device. Angled bearing faces on the muzzle device and the sound suppressor are pressed against each other by rotating the sound suppressor on threads which drive the angled bearing faces together, thus tightening the primary lugs within their sockets. Backup lugs on the silencer engage an annular groove on the muzzle device to retain the silencer on the firearm to which it is mounted in case of failure of the primary lugs. Rapid attachment and detachment are supported by these structures.

Abstract: A method for forming a weapon accessory mounting device to attach to a projectile firing weapon is disclosed. A flexure for receiving a body of the weapon accessory is formed.

A second attachment portion is formed at a second end of the flexure to attach the flexure to the weapon at a second attachment region. A first aperture is formed in the pivot portion configured to receive a pivot pin. A second aperture in the weapon accessory body receives the pivot pin at a weapon accessory body first end to attach the weapon accessory body first end to the pivot portion. The pivot portion is configured to convert at least a portion of energy of a weapon shock recoil from translational energy to rotational energy.

Abstract: Provided are methods and related devices for disrupting an explosive device using a propellant driven disrupter (PDD) that propels a rounded projectile (RP) toward an explosive device. The RP travels along a linear trajectory and impacts the target, including a barrier portion of the explosive device. The impacting between the RP and barrier forms a composite projectile via a solid state weld between a portion of the barrier and the RP distal end, thereby minimizing or avoiding spall and fragment generation into the explosive device. The projectile traverses a penetration distance along the linear trajectory, or a defined-angle relative thereto, to disrupt the explosive device without unwanted explosive detonation.

Abstract: A gun vise comprises one or more supports that move between a folded state, an extended state, and a locked state. A support is movable in both a sliding and rotating motion via an articulating mount to transition between states. In the locked state, a support is seated within a socket of a base of the gun vise to rigidly hold the support in position. In the folded state, a support has a reduced vertical footprint, such as to facilitate storage and transport.

Abstract: A weapon safety system with a target and a weapon with an automated lock. Each target is associated with an emitter which transmits a clearance signal that encodes an identifier. The encoded identifier may release the automated lock when received by a receiver attached to the weapon. In order to restrict the positions and orientations from which the weapon can fire to those surrounding the desired targets, shooting is enabled and the automated lock is released, when the following conditions are met: the clearance signal is received by the receiver, so that the receiver is within a first enablement area generated by a first aperture in the emitter; a measured optical power is above a predefined threshold; and the encoded identifier is validated.
