NIGHTFORCE XTREME DUTY ULTRALITE UNIMOUNT SCOPE MOUNT: When a tough, reliable mounting system is required without adding substantial weight, the Nightforce Ultralite Unimount is the answer. It features a CNC machined 7075-T6 hard anodized aluminum body and titanium beta series crossbolts and jaws. This unique design and construction provide the performance of steel at half the weight. The Nightforce Unimount is designed to remain attached to the scope at all times, allowing quick removal and installation on different guns. Precise tolerances ensure that the scope is not subjected to stress, strain, or bending as the ring screws are tightened. These Unimounts are for 30 mm scopes and are available in various heights and MOA taper (0 or 20 MOA). NOTE: Clean all mating surfaces thoroughly before mounting. Use a torque wrench and do not exceed recommended torque values: Crossbolts: 68 in-lb; Cap Screws: 25 in-lb. NIGHTFORCE ACCESSORIES: The Nightforce X-Treme Duty line is our most rugged and advanced Rings, Mounts, and Bases. A combination of Steel, Aluminum, and Titanium materials are machined to precise tolerances, producing a lightweight and strong mounting system that ensures the scope is not subjected to stress, strain, or bending as the ring screws are tightened.
