How long or deep is the range tunnel? Never built one but all Bass Pro Shops I have been in have a gun range for the gunsmith to bore site and zero in scopes. The tunnel as I would call it is painted flat black, and the lighting is directly above and to the side of the shooter. They use spot/flood light to illuminate the target. Only thing you can see is the target lit up light a Christmas tree. No glare or reflections.
