Don't buy a Lumizone!!! I have one and they are JUNK! Read the reviews on other websites and you will flnd that the rectical comes loose and rotates inside the scope. My Lumizone was working fine until I took it off of my Barnett Predator and put it on my new Bowtech Stryke Force. The whole front end feel off after about 20 shots. The tube is two pieces and the front is screwed into the windage / elevation housing. You want a scope that is a "one piece tube". I ordered a Hawke HK3246 in Camo. It is smaller and lighter than the Lumizone and has the same features. Ol'man
