The clamping mechanism is operatively configured to secure the strap within the sling clip when the weapon is in a firing position such that the strap minimizes movement of a muzzle end of the weapon caused by recoil of the weapon upon firing. The seating access is secured to the tailgate using suitable fasteners coacting with the tailgate. In one example, each of the individually controllable elements is selectively controllable to direct a respective part of the beam away from the pupil such that the proportion of the bean passing through the pupil is adjusted.
