These Mountain Tech 7214M 30mm scope rings feature a medium height, good for handling a lightweight rifle scope with an objective as large as 42mm. At .705 inches wide, the bands offer extra grip of the scope barrel, ensuring that you'll stay on target shot after shot, or after accidentally bumping a branch. The precision CNC 7075 aluminum and stainless steel hardware give them all-weather toughness, and the hardcoat anodized finish staves off environmental damage.
