Abstract: A firearm gas block assembly includes a gas block having a central bore and a retention member passage. The gas block engages a gas block journal of a barrel via the central bore. The retention member passage intersects the central bore to define an opening between the central bore and the retention member passage. A retention member within the retention member passage is moveable between first and second positions. A portion of the retention member extends through the opening when in the first position. No portion of the retention member extends through the opening when in the second position. Gas flow control discontinuities are within a surface of the gas block defining the central passage. A travel limiting member is engaged with the retention member and the gas block for limiting axial movement of the retention member to being between the first and second positions.

Abstract: A method of obtaining velocity of detonation (VOD) information from a borehole wherein an explosive in the borehole is ignited by initiation of a detonator, the method including the steps of using a control circuit which obtains a measurement of the VOD and which is subsequently destroyed by ignition of the explosive, and of transmitting from the borehole a wireless signal which contains the VOD measurement and data which identifies the borehole before the control circuit is destroyed.

Abstract: A method of adding digital functionality to a scope. A scope reticle from the scope is aligned with a virtual reticle from a digital overlay of an electronic display device coupled to the scope. The scope reticle is present in a first coordinate space of the scope image and the virtual reticle is present in a second coordinate space. The alignment of the reticles maps the first coordinate space to the second coordinate space. The coordinate spaces are then locked and the virtual reticle is made invisible, switching from a configure mode to an operate mode. Digital functionality can then be provided to the scope via the digital overlay. This may include an aiming indicator which works with the scope reticle.

Abstract: A firearm accessory mounting device is disclosed, comprising a nut, a collar coupled to the nut, and a follower captured between the collar and within a cam track of the nut. When the nut is rotated relative to the collar, threaded engagement secures the nut to the collar. Once the threaded engagement causes a torque threshold to be reached, further rotation of the nut causes the follower to extend radially inward to create a compressive force on a muzzle device and quickly and stably attach the firearm accessory mounting device.

Abstract: The devices, systems, and methods described herein are directed to a manual and assisted targeting system integrated into a weapon control system that includes dual triggers. One trigger is fully manual and is always operational. The second trigger is electronically controlled and is linked to aiming sensors, targeting sensors, and a controller comprising firing control logic. The firing control logic calculates an aim goal, based at least partially on location information pertaining to the target, and determines when the difference between the aimpoint of the weapon and the aim goal is below a threshold. In response to this determination, a control signal is sent to a trigger actuator to fire the weapon.
