Designed to attach riflescopes with a 30mm maintube to a 9-11mm or 3/8" mounting system, this Match Mount from Hawke Sport Optics features a two-piece anodized aluminum alloy design along with a medium profile that positions the center of the scope 1.1" above the mount. The scope is secured in place with double hex screws and internal cushion tape to prevent marking or damaging of the scope's exterior. A retractable recoil stop pin is also integrated into the design to maintain the scope's position during use.
