Offering solid mounting and reliability, the medium Vortex Optics Pro Series 30mm Riflescope Ring places the maintube's centerline 1.0" from the top of your rifle's Picatinny/Weaver rail. Offered here as a pair, the rings are made from the lightweight and durable 7075-T6 aluminum alloy treated with a scratch-resistant anodized finish. An integrated recoil lug on each ring helps to spread the recoil force over a larger area for better long-term performance. Each ring comes with a clamp-style Picatinny/Weaver rail mount, fits standard 30mm maintubes, and the ring cap is secured in place with four T-25 Torx cap screws.
