Warne Tactical Rails are machined from solid steel in both standard and 20 MOA configurations. The Tactical Rail allows the use of Picatinny or standard Weaver style rings and provide a strong and true platform for optics mounting. Cross slots feature the 1913 Mil-Spec design. Bases securely mount to your gun with T-15 Torx style screws, 25 in/lb. of torque recommended.
