The Valken 1” Riser Mount with 8 ring slots is a rifle accessory that mounts to a flat top picatinny rail. This tactical riser mount is used to raise an optic’s line of sight by 1”, and locks firmly into place with two thumb screws. It installs in seconds, and is very helpful when using with red dot sights. We recommend our Valken RDA30 red sot sight for use with this riser when you need those longer ranged shots.
