These flip-up 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 caps can be rotated to provide the opening angle preferred by the shooter. Nightforce lens caps are made of extremely tough, heavy-duty black plastic. Unlike lesser quality covers, they will not accidentally detach from the riflescope, they are not affected by extreme environments, and they will not deteriorate. They are designed specifically for high-quality riflescopes, providing years of effective protection against dust, moisture, abrasion and scratches. They are quick in the field with positive response and are designed to be left on the riflescope at all times.
