The killFlash ARD is endowed with anti-glint capability that helps protect the optics glass from factors like sand, dirt and grime. Not only does it lessen objective lens glare and reflection but also protects the lens from scratches and damage. The cover, on the other hand, easily flips up and out of the way at the time of action. The installation of the Tenebraex SB5605-FCA anti-reflection device with the flip lens cover helps extend the life of the rifle scope it is paired with.
