A trajectory correcting device includes a first trajectory adjustment mechanism and a second trajectory adjustment mechanism. The first trajectory adjustment mechanism is configured to change an angle between a mounting member and a sight or a second mounting member. The second trajectory adjustment mechanism is configured to rotate the sight or mounting member about an axis different than the adjustment axis of the first trajectory adjustment mechanism.

A crosslock assembly comprising a base having a chamber formed therethrough, wherein the chamber is surrounded by a distal wall. The distal wall comprises an interior wall oppositely formed with an exterior wall, wherein an opening is formed between the interior and exterior walls. The assembly further comprises a crosslock having a shaft upon which a support member is disposed, and a housing having a channel formed therethrough. When assembled, the housing is disposed within the chamber of the base, and the shaft of the crosslock is disposed through the opening of the exterior and interior walls of the distal wall of the base such that the support member is disposed within the channel of the housing.

Provided is a dot sighting device with large caliber for binocular vision in which sighting can be performed rapidly and accurately by minimizing parallax. The dot sighting device is attached to and detached from a mount for a heavy machine gun. In addition, by using the dot sighting device with large caliber, a user can rapidly and accurately sight and fire a target by taking into consideration types and characteristics of the target and a distance to the target.

A folding sight assembly, comprising a housing having a lower region that is configured to hold a crosslock, and an upper region comprising a catch plate separated from a windage adjustment plate by a space. The assembly comprises a shaft and an engagement spring. The engagement spring comprises a longitudinally extending body that turns to form a retaining loop portion comprising an arcuate-shaped member having an opening formed therethrough. The shaft is disposed through the opening of the engagement spring and within the space formed between the windage adjustment and catch plates, and the engagement spring is further engaged with the housing and the crosslock to secure the component parts of the folding sight assembly to one another.
