The Company That Manufactures Your Flip-up Scope Cover: Tenebraex Factory Tour

By Dickson Ly

When one purchases a new rifle scope, most of the time it comes packaged with a set of loose, cheap bikini-type covers that most owners would simply leave in the box. When one acquires a high-end rifle scope from reputable brands such as Schmidt & Bender and Nightforce, they include a set of quality flip covers that are made in Canada by a company called Tenebraex.

Tenebraex became a division of Armament Technology which is also their exclusive distributor worldwide. Their product portfolio includes KillFLASH® Anti-Reflection Devices, Tactical Tough® Scope Covers, Weapon Sight Polarizers and Laser Filter products. They supply KillFLASH® to various U.S. and NATO military forces by the millions.
