Vortex Cantilever 30mm Riflescope Ring with 1-inch Offset & Lower 1/3 Co-Witness - CM-304
Ideal for use alongside your Vortex red dot sight, the Vortex Cantilever 30mm Riflescope Ring with 1-inch Offset and Lower 1/3 Co-Witness was engineered to allow you to co-witness your front sight using the attached optic. It has a 1-inch offset that positions the scope in a forward position, allowing for correct eye relief and head placement. The cantilever ring positions the center of the riflescope tube positions the center of the scope 1.57-inch (40mm) above the rail. It provides a lower 1/3 co-witness that allows you to see over fixed sights.
The Vortex Cantilever 30mm Riflescope Ring with 1-inch Offset and Lower 1/3 Co-Witness provides extra rail room for rear Back Up Iron Sights (BUIS). This cantilever mount was built to last and is compatible with most 30mm red dot sights. The cantilever ring has a conveniently integrated Picatinny rail mount.
