Our History

The Armament Technologies team happen to know what they're talking about. Not only do they include engineers and designers, but high end precision marksmen as well. They know that the investment you make in your rifle and your riflescope is significant. So they set out in 1992 to create an affordable line of accessories to address the dangers of reflection.

Reflections being seen by an enemy have determined the outcome of many famous battles and skirmishes, including the battle for Henderson Airfield in the Battle of Guadalcanal, the Carlos Hathcock—NVA sniper duel during the Vietnam war, the Zaitsev-Koning sniper duel in the Battle of Stalingrad, and the battle of Little Round top at Gettysburg (reflections from equipment). Moshe Dayan, the Israeli general, got his famous eye patch when a sniper saw reflection of the sun from his binoculars.

Tenebræx® products offer patented technology that work to prevent reflection and enhance the use of your riflescope. Tenebræx® products are used by militaries, international competitors, and expert hunstmen alike. The Tenebræx® line offers Anti-Reflection Devices, Optical Filter Systems, Polarizers, SunGuard, and Tactical Tough Flip Covers for most brands and models of riflescopes on the market.

Why invest in quality optical protection? Serious marksmen understand that a precision riflescope is a critical component of their shooting system. In fact, high-quality optics often outweigh the importance of the rifle itself. Your riflescope magnifies targets at distance, enhances focus, reduces light loss, and eliminates glare. Superior glass delivers better color fidelity, sharper contrast, and increased image clarity—all translating to improved accuracy, extended range, and enhanced safety in the field. Today's advanced optics feature precision adjustment knobs, illumination enhancement, variable magnification, and parallax compensation.

With such a significant investment in your gear, premium protection is essential. Military-grade scope caps and flip-up scope covers shield your valuable glass from harsh elements, debris, and accidental damage that can compromise performance. Tenebraex® products are engineered for serious professionals. Trusted by military and special forces units worldwide, our tactical flip-up scope covers feature a precision engineered locking mechanism that remains securely closed when needed yet instantly flips out of your field of view when deployed.
