The quick release cantilever bracket is designed to install a 30 mm telescopic sight.
The offset of the cantilever bracket positions the sight in the front position, thus providing the correct sight distance and head position when in use.
The precision optical base is made of 6061 T6 aluminum alloy and is coated with 3 Mil anodized black hard coating. The surface is rock solid and durable. The base of the sight frame allows the focus eyepiece to quickly and easily aim at the mark line and easily change the magnification.
