The XS Long Rail with Ghost Ring for the Ruger Gunsite Scout rifle allows you to mount optics in the traditional position over the receiver or out in front of the receiver. It is machined from billet aircraft aluminum and finished with hard coat anodizing. The long rail installs using the factory mounting holes but it extends over the receiver to give you more flexibility in mounting your optic. This rail also features a rear peep sight that works with the factory front sight and is fully adjustable for windage and elevation.
