DNZ's Hunt Masters two piece scope mounts are custom made to fit each type of firearm and align perfectly with your rifle's receiver. Each ring and base is machined from top-grade aluminum, which absorbs shock and withstands temperature extremes at a fraction of the weight. The Hunter Masters uses a internal ring and base design which allows for extra eye relief adjustment and has up to four times the threads of other mounts for absolute strength and security. This model is compatible with Remington 700/Howa 1500/Weatherby Vanguard rifles and has 1" rings with a black matte finish and a medium mount height. It uses two screws.
