US12379186 - Adjustable sight assembly

In one example, the disclosure relates to adjustable flip up sight assembly that can be adjusted vertically and laterally in particular, for an automatic firearm, comprising a front sight support element that is supported by an axle on a mount, in particular such that they can pivot thereon, wherein the front sight support element has an adjustment element supported on a spring element and releasably connected to a front sight, which contains a keyhole type opening through which the axle is inserted, wherein the adjustment element can be moved in relation to the axle against the spring force between two positions inside the front sight support element such that the keyhole opening prevents a lateral movement of the front sight support element along the axle when engaged with the axle, and allows the lateral adjustment of the front sight support element in a released position.
