Designed specifically for use with the AR-15 platform, this 1-Piece scope mount allows the optic to be mounted farther forward on the receiver to provide correct eye relief. The 6-screw design provides increased clamping force to keep the optic in place during recoil and the integrated articulating anti-cant mechanism helps keep the rifle level for your long distance shots. Centerline height from top of rail: 1.400 in.
