A sight adjustment assembly has a frame with a clamping mechanism for receiving and clamping a handgun slide with an attached stationary sight and an adjustment mechanism for engaging and adjusting the sight in a lateral position with respect to the slide. The sight adjustment mechanism and the clamping mechanism are contained within an outer periphery of the frame during storage and use to thereby provide a compact device that can conveniently accompany a user for sight adjustments in the field.

A rifle scope alignment apparatus having a light source that shines through a void space and through a rifle scope. The rifle scope alignment apparatus has two stepped wedges that engage the front end of a rifle scope and has a flat top v-groove to engage a rifle barrel. The light source illuminates the crosshairs of the rifle scope which casts a shadow of the crosshairs onto an elevated diamond-shaped target having a rounded hole and a vertical line and horizontal line.

A zero-stop mechanism comprises first and second stop members and a movement limit member. The second stop member is releasably secured to an adjustment mechanism. The movement limit member extends around a turret assembly and has a substantially annular main body from which a lug extends. In a first rotational direction of the adjustment mechanism, the second stop member comes into contact with a first side of the lug whereby the main body is rotated in the first rotational direction until a second side of the lug comes into contact with the first stop member. In a second rotational direction of the adjustment mechanism, the second stop member comes into contact with the lug second side whereby the main body is rotated in the second rotational direction until the lug first side contacts the first stop member.

An aiming device is provided including an illumination device and an optical element wherein the illumination device projects a primary dot and at least one secondary alignment dot distal from the primary dot to aid a user in obtaining a view of the primary dot when the aiming device is in an aligned mode, the primary dot is visible within a field of view of the user, but the secondary alignment dot is not visible. When the aiming device is in a misaligned mode, the secondary alignment dot is visible to the user, but the primary dot is not. The secondary alignment dot provides instruction to the user to realign the aiming device relative to the field of view of the user so that the aiming device transitions to the aligned mode. A related method of operation is provided.

A boresighting mechanism for adjusting an armament of an aircraft. The mechanism includes a housing comprising a proximal end, a distal end, and an inner cavity. The mechanism further includes a jackscrew with a threaded portion disposed in the inner cavity and an unthreaded portion extending from the proximal end of the housing. The mechanism further includes a follower threadedly coupled to the jackscrew at a first end within the inner cavity and extending from the distal end of the housing. The follower is configured to be coupled to an adjustment feature of the armament at a second end. The mechanism further includes an adjustment knob coupled to the unthreaded portion of the jackscrew and configured to rotate the jackscrew to thereby cause linear motion of the follower. The linear motion allows for adjustment of the armament via the adjustment feature.

A compensating mechanism includes a base, an adjusting unit, an adjusting cover and a stop unit. The adjusting unit is disposed in the base. The adjusting cover connects to the adjusting unit and includes a curved groove. The stop unit is disposed between the adjusting unit and the base and includes a pin. When the adjusting cover is rotated, the adjusting unit is only rotated with respect to the base and the stop unit is axially moved with respect to the base so that the pin enters or leaves the curved groove.

The present disclosure provides a sight adjuster. The sight adjuster includes a frame, a horizontal clamping mechanism disposed on the frame, a vertical clamping mechanism disposed on the frame, and an adjusting mechanism disposed on the frame. The vertical clamping mechanism includes an upper fixing portion and a lower fixing portion. The lower fixing portion is disposed on a bottom portion of the frame. The lower fixing portion includes a lower driving piece, a support board and a bracket hinged to the support board. The lower driving piece drives the bracket to move along a vertical direction.

A handguard assembly for attaching to a firearm is disclosed. The handguard assembly comprises an upper component, a lower component, a front cap, and a rear cap. The front cap and rear cap are secured within the lower component. The front cap and rear cap have curved top sides for supporting the barrel of the firearm. The lower component has slots in the sides to receive tabs from the sides of the upper component. When the upper component and lower component are attached to the firearm, the components work together to position the barrel in the preferred position so that the sights of the firearm are zeroed when the handguard assembly is attached to the firearm.

The present disclosure provides a sight adjuster. The sight adjuster includes a frame, a horizontal clamping mechanism disposed on the frame, a vertical clamping mechanism disposed on the frame, and an adjusting mechanism disposed on the frame. The vertical clamping mechanism includes an upper fixing portion and a lower fixing portion. The lower fixing portion is disposed on a bottom portion of the frame. The lower fixing portion includes a lower driving piece, a support board and a bracket hinged to the support board. The lower driving piece drives the bracket to move along a vertical direction.

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.
