Hi-Lux Optics Malcolm 3x70mm Rifle Scopes 3/4 in Tube Second Focal Plane Fine Cross Reticle Matte Black. This mount is designed to provide spot on 1/4 MOA adjustments when the front and rear mounts are spaced 7.250" from center to center. The turret adjustment mark ring has been polished for easier reading and more precise adjustments. It also features standardized configuration with crescent cut scope blocks offering improved compatibility and ease of use. The scope is also equipped with a sliding lock ring that mitigates the recoil energy going through the optic. Prior to every shot you will need to pull back on the scope to "reset it to battery."
