Lyman 17 ATC 0.3/8" Height Scope Mount Rings Set
Lyman #17AUG Tunnel Sight with a height of 0.852 inches and a 3/8-inch blue steel dovetail base, engineered for precision shooting and metallic reloaders seeking enhanced sight alignment and target acquisition. This sight tunnel is meticulously machined from a single solid piece of high-grade steel, ensuring exceptional durability and resistance to wear under rigorous field conditions.
The overall height measurement is taken from the bottom of the dovetail slot at the center of the aperture, providing consistent and repeatable mounting specifications for seamless integration with a variety of rifle platforms equipped with dovetail rails.
Included with the sight are eight interchangeable aperture discs, each securely locked in place via a threaded cap mechanism. This design allows shooters to quickly switch between different aperture sizes to optimize sight picture and target clarity depending on shooting distance, lighting conditions, and ammunition type, whether metallic or semi-metallic cartridges.
