The light is a Terra Lux TT-4. I got it for a song a while back. Dual switches and 520 lumen. It needed a place on a rifle.

I like the mount. The TT has way to many cool looking bands and bumps. I have probably reset the light 8-10 times before It sat level with the barrel and far enough forward for me.

I like the way it sets. It keeps the light forward of the barrel and sight and far enough offset to no interfere with the Holo sight.

It's a keeper. I was planning on getting the single set Sure fire G2 320 lumen but I just had the TT-4 as a spare in my work bag. So I save some money and its a perfect light for the setup.

My biggest concern is hitting a mirror or shiny surface and blinding myself for a bit during a search. That sucker is bright.
