Ultra-light tactical scope rings from Hawkins Precision are made in America out of a single billet of 6061 T6 aluminum. These fully machined rings feature a rigid, corrosion-resistant, black anodized finish. The rings feature with a base clamp made from 7075 aluminum, and a heat treated stainless steel cross bolt to deliver extra strength, re-mount ability, return to zero, and grip where it counts. The ultra-light design frees you from carrying unnecessary bulk and the rings come standard with an anti-cant level cap.
