The present disclosure describes an adjustment mechanism for a scope comprising: a first surface and a second surface, the first surface configured to engage the second surface axially when an amount of force is applied to the first surface, the first surface also configured to transfer torque applied to it to the second surface when the first surface and the second surface are engaged, and a member adjustable to apply force to the first surface to engage the first surface and the second surface, the member being adjustable using only one or more human fingers, wherein an adjustment of the member can always be initiated using only one or more human fingers.

An image offsetting apparatus for producing an offset image pathway and presenting the offset image pathway to an optic, including at least some of a mirror assembly wherein the mirror assembly comprises a first component mirror and a second component mirror, wherein the mirror assembly is attached or coupled so as to provide the offset image pathway that is offset from a direct image pathway between a target object and the optic.

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.

A method for calculation of firearm sight calibration instructions by processing an image of a shooting target. The method comprises receiving at least one image from at least one imaging device, the at least one image depicts a shooting target with a shot group comprising a plurality of bullet holes, receiving an indication of a firearm type and/or a firearm sight type to calibrate, using at least one hardware processor for calculating firearm sight calibration instructions according to at least one relative location of one of the plurality of bullet holes in relation to another of the plurality of bullet holes by processing the at least one image and at least one predefined parameter of the firearm and/or the firearm sight type, and outputting presentation instructions to present the firearm sight calibration instructions on a display of a client device.

A boresighter/trainer fits into a distal end of a gun barrel and includes a sound sensor, a circuit, a laser, and a power source. The boresighter/trainer has at least two operational modes: one in which it continuously emits laser light and one in which it emits laser light for a short duration when the sound of a firing pin is detected. When in its first mode, the boresighter/trainer permits laser light to be projected along the longitudinal axis of a gun barrel in which it is portioned, for the purpose of aligning a sight on the firearm. When the boresighter/trainer is in its second mode and the firing pin of the gun is activated, the sound of the firing pin is detected by the sound sensor and activates a circuit in the boresighter/trainer to cause the light source to emit light along the longitudinal axis of the firearm barrel. The boresighter/trainer may have multiple bore adapters that fit different firearm bore diameters.

A digital sight for a weapon includes a sight body, a mount for a peripheral fixed to the sight body, and a controller. The controller is disposed in communication with a non-volatile memory and is responsive to instructions recorded to boresight a peripheral relative to the digital weapon sight. Weapon assemblies and methods of boresighting peripherals to digital weapon sights are also described.

A lens assembly for a weapon sight includes a first lens having an optical axis and a focal plane array (FPA) coaxial with the optical axis of the first lens. A first parameter of the first lens is selected that minimizes an error in image shift when the weapon sight lens assembly is adjusted for focus. The first parameter of the first lens can be at least one of a lateral position, axial displacement, thickness, effective focal length, material, effective focal length, radius of curvature, conic constants, and higher order aspheric coefficients of the first lens. A sensor can detect a position of the lens and a processor can compare the measured position to an ideal position and use a lookup table to display a corrected reticle position or corrected scene. An actuator may move the lens to the ideal position from the measured position.
