Q. Why do I have illumination issues with my Tremor3 or H59 reticle?
A. Due to licensing agreements with Horus, we are limited in what we can illuminate to only the center dot and (on the Tremor3) the 2, 4, 6, and 8 MRAD dot below the horizontal crosshair. Our illumination module is also designed to limit stray light emissions from the front of the scope, which means that illumination on the Horus reticles we offer is optimized for use in low light and clip on night vision. As such, you may not be able to see the illumination with the naked eye during the day.
Q. What rings should I use?
A. We mostly use Badger Ordnance and Cadex Defence mounts here, but any high end mounting solution will work well for you as long as you take care to follow the torque guidelines set out in the instructions.
Q. What is the torque spec when installing my Tangent Theta scope?
A. For our TT525 and TT315 'P' series scopes (34mm tube) we recommend up to 25 in/lbs. For our TT315M & LHR (30mm tube) we recommend 15 in/lbs.
Q. What is the warranty for my TT?
A. We offer a lifetime warranty against manufacturer defect, and we conduct all warranty and non-warranty repairs at our facility here in Halifax. The same people who built your scope will be the ones to look after it in the unlikely event it needs any work done.
Q. How do I clean my scope glass?
A. First, use a soft brush or cloth to remove any dirt or grit. Then use either the microfiber end of the included lens pen or a quality microfiber cloth to clean the lens. Use a circular motion, working from the inside to the outside.
