Systems for leveling a firearm receiver and aligning a scope to the receiver are precisely fabricated and assembled to maximize accuracy, including high sensitivity spirit levels. A bar assembly with a high sensitivity spirit level is received in the receiver with the bar in direct contact with the receiver rails. The bar may directly contact the full length of the receiver rails. A plate assembly includes a lower plate for connection to a bench rest, an upper plate for connection to the receiver, and a mechanism to pivot the upper plate relative to the lower plate about a pivot axis for windage adjustment. Methods of use are disclosed.

The invention discloses a wireless control structure of an aiming device comprising a remote controller and a wireless receiver connected wirelessly therewith. Said wireless receiver is installed on the aiming device and is connected with the switch of aiming device; said remote controller includes the remote control chip and keys, indicator light and transmit antenna connected with the remote control chip; said wireless receiver includes the receiving chip and receiving antenna connected therewith. The invention has achieved wireless control of aiming device via a wireless control structure of aiming device and simplified control structure of current aiming device, making the control of aiming device more convenient and visually beautiful.

A target adjustment apparatus may be provided. The target adjustment apparatus may include an optical targeting device having a first zero. The target adjustment apparatus may further include an optical adjustment lens removably disposed in a line of sight between a target and the optical targeting device. The optical adjustment lens may shift a target image before it reaches the optical targeting device, creating a second zero.

A universal marksmanship training system is disclosed herein configured to utilize a display device comprising a graphic display. A software application may also be provided. The software application is often configured to display a virtual target on the graphic display. A chamber insert may be utilized, the chamber insert configured to be positioned with the firing chamber of a firearm to be zeroed, wherein the chamber insert interacts with the software application to determine alignment of a bore of the firearm to a bore alignment point on the graphic display. In one form, the display device displays a sight target on the graphic display wherein the sight target is visually perceived by a marksman and is offset from the bore alignment point by an offset distance. In one form, the software application calculates the sight target relative to the bore alignment point of the firearm given a set of condition variables.

A ballistic correction device for sight members (of weapons) provided with an elevation adjustment turret is described. In particular, the device comprises detecting means, outside of the turret, to detect the rotations imparted by the shooter to the adjustment ring of the elevation turret, and displaying means to display the shooting distance and/or other shooting settings corresponding to the position the ring assumed. The device displays, for the shooter, the calibration of the turret from the moment the shooter observes the device. The shooter is no longer required to keep in mind the last calibration carried out. In the step of carrying out a new calibration, it is no longer necessary to consult the compensation tables, but simply to read the values displayed on the device as the ring of the turret is being rotated. A method for correcting the elevation of the weapon is further described.

A system, method, and device for configuring an optical aiming device for ballistic drop compensation (BDC). The optical aiming device can include a housing with a reticle pane defining a reticle display field viewable by a user and indicating a zero point, the housing further including a plurality of axially spaced lenses and defining an optical path therethrough. In various embodiments the system includes a display device configured to project an image generated from a display, a processor, and a non-transitory computer readable storage medium. The computer readable data storage medium can include instructions executable by the processor to receive a first set of ballistics input data indicating a first type of ammunition, determine a BDC pattern including at least two holdover marks corresponding to at least two ranges for the first type of ammunition, and project the BDC pattern onto the reticle display field.

A device and method for aligning a sighting device with a reference. The device includes features conforming to an industry standard for attaching accessories to a firearm. The device contains features which allow the device to be leveled relative to a removable level. A sighting device may be attached to the device using the industry standard features. Once attached, the sighting device may then be aligned using either the removable level or an external reference. Once the sighting device is secured in its mount, the mounted sight may then be installed and removed from one or more devices without its calibrated orientation being altered.

A level indicator system for an aiming system comprising a base assembly, a level assembly. The base assembly comprises a base member defining a base axis, a plate, and a support member. The level assembly comprises a level indicator defining a level axis. The base member and the plate support the support member such that a location of the plate relative to the base member is adjustable. The support member supports the level assembly such that a location of the level axis relative to the base axis is altered when a location of the plate relative to the base member is adjusted.
