Trijicon Tenebraex KillFlash ARD for 6x48 ACOG AC11016 is the perfect combination of an anti-reflection device and flip-up lens cover. While the ARD boasts of a unique geometry along with an extremely advanced honeycomb material to hide reflections from optical surfaces, the flip open cover does the job by protecting the optic. The killFlash ARD is endowed with anti-glint capability that helps protect the optics glass from factors like sand, dirt and grime. It protects the lens from scratches and damage, and offers an inexpensive, retrofittable, field-practical way of reducing objective lens glare and reflection. The cover, on the other hand, easily flips up and out of the way at the time of action. The installation of the Tenebraex AC11016 anti-reflection device with the flip lens cover enhances the life of the rifle scope it is paired with. It is especially made in compatibility with Trijicon ACOG 6x48 devices. Trijicon 6x48 ACOG Tenebraex KillFlash ARD AC11016
