The ATN 1-Piece Dual Cantilever Quick Detach Scope Mount (ATN part no. ACMUDCQDM2) is a hardened aluminum alloy mount built for 30mm tube scopes, including ATN’s X-Sight 4K, ThOR 4, and ThOR LT series. The one-piece base and ring combo uses a cantilever design to position your optic for correct eye relief, while the adjustable quick-detach mechanism lets you move the scope from rifle to rifle and retain zero each time. It fits both Picatinny and Weaver rails, so it works across a wide range of rifle platforms. If you run the same optic on multiple guns, this mount is built specifically to make that swap fast and repeatable.
