The Trijicon TA66 Tenebraex killFLASH Anti-Reflection Device is purpose-built for use with compatible 3.5×35 ACOG riflescopes, helping to reduce unwanted glare and reflections from the optic’s objective lens. Utilizing a specialized honeycomb grid design, the killFLASH works by minimizing the amount of light that can reflect directly off the front lens, reducing the visible signature that may otherwise reveal a shooter’s position. This makes it a valuable addition for tactical applications, hunting environments, and precision shooting scenarios where maintaining a low visual profile is important. Designed specifically for the dimensions of the 3.5×35 ACOG, the TA66 provides a secure and precise fit while preserving the optic’s intended performance.

Engineered by Tenebraex and trusted by professionals worldwide, the Trijicon Tenebraex killFLASH is constructed from durable materials capable of withstanding demanding field conditions, including exposure to harsh weather, dust, and regular use. Despite its protective anti-reflection design, the device allows for excellent light transmission and maintains a clear sight picture with minimal impact on image quality during daylight operation. Its lightweight construction adds virtually no noticeable bulk to the optic while helping protect the objective lens from incidental contact and environmental debris. Easy to install and built to complement the rugged reliability of the ACOG platform, the Trijicon TA66 Tenebraex killFLASH is a practical upgrade for users seeking enhanced concealment, lens protection, and confidence in the field.
