Nightforce Optics Flip-Up Objective Lens Caps are manufactured to exacting specifications by Tenabraex and are built to withstand the harsh punishment exacted through heavy use in the field. The caps attach to the objective lens of the riflescope through the use of an adapter, which threads in and provides a locking point for the caps. The lens covers open with a simple push of the finger and can be locked into place with rearward pressure. The caps are designed for ATACR 25x second focal plane models and ATACR 35x first focal plane models. Mfg: Nightforce
