These Nightforce Optics Flip-Up Objective Lens Caps, manufactured to Nightforce specifications by Tenabraex, provide both superb protection and extreme functionality in the field. For the riflescope's objective lens, an adapter screws into the objective's threads of the scope. The caps themselves then securely lock into place onto the adapters. The caps flip up easily with finger pressure. Once open, the caps can be locked into place with slight backwards pressure. The lens caps are designed for the company's NXS riflescopes and fit options in that line equipped with 50mm objective lenses. Mfg: Nightforce
