A device and method for stabilizing a rifle scope that employs a pocket cut in the bottom of a scope base (picatinny rail) that precisely mates with a key formed on the top of a recoil lug, such that when the scope base is attached to the rifle's action receiver and mated with the lug's key, the lug holds the barrel and the scope base locked in tandem so that they move exactly together during recoil events or any vibrations experienced by the rifle.

A system and method for activating an optic for a gun. A magnetic field from a magnet proximate the optic is detected. Power to the optic is turned off from a battery of the optic in response to detecting the magnetic field. Power to the optic is turned on from a battery in response to not detecting the magnetic field.

A device for achieving linear movement in one direction and stiffness in all other directions. As an example, a recoil causes strong forces in a linear movement, but any ridges will produce errors as two units each try to return to its original position. The device is a damper. The linear displacement by a recoil is mitigated using two set of blades, one absorbing the linear recoil, and a second for hindering the linear parallel deflection of the first set by the recoil or for increasing the stiffness provided by the first set of blades. The produced errors are much smaller or none as the recoil is mitigated using the very strong damper.

Devices mountable to a rail having a recoil groove are provided. In one aspect a device mountable to a rail having a recoil groove has a rail positioner having a longitudinal length with a plurality of teeth arranged along an edge of the longitudinal length and a recoil groove insert extending away from the rail positioner and configured to be inserted into the recoil groove, a first body member having a first rail engagement surface and plurality of openings generally sized to receive the plurality of teeth and arranged along a length of the first body

a second body member having a second rail engagement surface opposite the first body member, and a clamping structure operable to tighten and maintain a clamping force between the first body member and the second body member when the rail positioner is arranged in therein and that can be released facilitate installation and removal of the mounting to a rail.

An alignment subsystem that incorporates a ball and lever approach to adjust windage and elevation. The system provides a low cost, vibration immune red dot and/or reticle device for a weapon system. The materials used to construct the system also provide for temperature indifference and increased wear characteristics.

Disclosed is a shock absorption device for photoelectric instrument for gun, comprising a bracket, a buffer mechanism, and a connection mechanism; a card block is formed on the bracket, and a perforation is formed on the card block; the buffer mechanism includes a buffer seat, a slide bar, and a cushioning elastic; the connection mechanism is mounted on the bracket and used to be detachably connected to Picatinny rail on a sniper rifle. When shooting, the sniper rifle recoils, the sniper rifle drives the Picatinny rail to recoil, the Picatinny rail drives the bracket to recoil through the connection mechanism, the bracket acts on the cushioning elastic, and the cushioning elastic contracts, which can buffer the photoelectric instrument for the gun installed on the buffer seat, reduce the recoil of the photoelectric instrument for gun, and prolong its service life.

A rifle holder hinge mechanism comprising a rifle hook attached to a hinge block, the hinge block having a hinge block sleeve, with a hinge pin rotatable within the hinge block sleeve. A cam is provided connected to the hinge pin and configured to arrest rotation of the hinge pin, such that the hinge pin is rotatable from a first position to an approximately 90-degree second position. In some configurations, a retaining collar with a first detent and a second detent functions as the rotation limiting cam.
