The 6x48 ACOG is a high-magnification combat optic that delivers outstanding reach and optical quality — and the large 48mm objective lens that makes it so capable in low light also creates a larger reflective surface that can give away a position under the right lighting conditions. The Trijicon 6x48 ACOG Tenebraex KillFlash ARD AC11016 eliminates that vulnerability directly by placing a precision honeycomb anti-reflection filter over the objective lens, killing forward light reflection without affecting the sight picture the shooter sees through the scope. The ACOG with KillFlash Tenebraex ARD is the standard that serious users reach for when they want anti-reflection protection that fits correctly and performs reliably. Tenebraex manufactures KillFlash filters to precise dimensional tolerances for specific optic configurations — which means the Trijicon ACOG 6x48 KillFlash AC11016 seats correctly on the 6x48 ACOG objective housing without gaps, wobble, or misalignment that would compromise either the anti-reflection performance or the optical image quality. A KillFlash that fits the specific optic it was designed for works correctly every time. The ACOG 6x48 KillFlash honeycomb structure allows light to pass through to the objective lens normally from the shooter's perspective while eliminating the forward light reflection that an unprotected objective produces. From the front, the objective goes dark — no light glint that reveals position to game animals or adversaries scanning for equipment signatures. The sight picture through the scope remains clear and unaffected by the ARD filter. The AC11016 is designed specifically for the 6x48 ACOG objective housing — a direct-fit solution that installs without tools and stays securely in place through field use and recoil.
