A rotational sighting apparatus includes a base, an aiming member and a pressing pivotal axle. The base includes a main body, a side cover and a through hole formed on the side cover. The side cover further includes a locking portion adjacent to the through hole. The aiming member includes a rotating portion and a pivotal attachment hole formed to penetrate through the rotating portion. The pressing pivotal axle penetrates through the pivotal attachment hole to connect with the rotating portion via the through hole. The pressing pivotal axle includes a locking key moveably locked onto the locking portion and an elastic element configured to drive the pressing pivotal axle to rotate. Accordingly, when the locking key disengages from the locking portion, the elastic element drives the pressing pivotal axle to allow the aiming element to rotate from a first position to a second position.

A gunsight system for aiming a firearm is disclosed. The gunsight system includes a front sight and a rear sight. The firearm has a barrel defining a bore that extends along a gun bore axis. The gun bore axis extends in a forward direction and a rearward direction. The front sight comprises a front sight post including a front sighting element. The rear sight comprises a rear sight post including a rear sighting element. Each sight post is pivotable between a deployed position and a reclined position. When the sight post are in the deployed position, the user may aim the firearm with reference to a sight line extending through the front and rear sighting elements. The sight line and the gun bore axis may be generally parallel to one another when the sight arms are in the deployed position.

A rear sight assembly for a firearm is disclosed. The rear sight assembly contain a sight base coupled with the firearm, a sight blade pivotally coupled with the sight base and a tension member positioned between the sight base and the sight blade and configured to push the sight blade against the firearm.

In an adjusting knob mechanism, a base includes a first supporting portion and a second supporting portion. A first clicking gear includes a plurality of first indentations and disposed on the first supporting portion. A second clicking gear includes a plurality of second indentations and disposed on the second supporting portion. A limiting element is disposed on the base. A movable element is disposed within the limiting element and configured to move in an axial direction of the base relative to the limiting element. A connecting mechanism extends into the limiting element. An adjusting cover is connected to the movable element by the connecting mechanism, so as to move the movable element in the axial direction of the base relative to the limiting element and the second clicking gear. The adjusting cover is configured to rotate the limiting element and the movable element through the connecting mechanism.
