Just ordered a new T3x lite 308. Suggestions for optics setup, rings, picatanny rails? I need to keep it close to $500 if possible. I will be shooting game with it from 50-400 yards,elk,whitetail,mule deer, antelope, maybe a black bear,caribou also. 2x-8x does catch my eye, but what millimeter tube would be optimal. What do you have for setups/suggestions and any suppliers that carry the goods. Thanks.
