Vortex Strikefire 2 Red/Green dot scope with mount. Great for AR. I bought this, mounted it, used it once, and unmounted it. I decided I wanted a variable power magnified scope instead of a red dot. It is a great scope and one of the best values in red dots out there. Vortex has a lifetime warranty on all of their products. If something goes wrong, they just give you a new one! The scope is in near perfect condition. The only thing is when I attached it there was some scraping on the nut. I have attached pictures. The rest of the mount and the scope are perfect. Normally sells for $179. Because of the knob, I'll sell for $130. Portland area.
