Primary Arms Deluxe Extended AR-15 Scope Mount Features The Primary Arms Deluxe Extended AR-15 Scope Mount is purpose built for mounting a 30mm tube variable power optic in the extended nose to charging handle position on AR-15 and M4 pattern rifles. This forward mounting position is a favorite among shooters running 1-4x and 1-6x low power variable optics since it keeps the scope s eye box positioned for fast target acquisition at close range. Mounting directly to M1913 Picatinny rails the mount drops onto any standard flat-top upper receiver without requiring gunsmithing or a proprietary rail system. A full 2.28 inches of clearance between the rings allows room for larger turret housings and illumination dials common on LPVO scopes. Machined from aluminum the mount is finished in a matte black anodized coating that resists wear and corrosion through heavy use in the field or at the range. The mount sets the center of a 30mm tube scope at 1.5 inches above the rail a height chosen to work well with a standard cheek weld on most AR-15 configurations. This combination of correct height generous clearance and a tough anodized finish makes it a dependable foundation for a fast handling optic setup.
