Vortex Spitfire HD Gen II 3X prism scope red dot optic

Selling this as I upgraded. The optic is in mint condition. Used maybe 3-4 times in an indoor range. Was mounted on one of my rifles. Looking to sell it. It's $629 + HST new. Selling for $500 and I'll ship anywhere in Canada (at no extra cost). See pics for details. Comes with everything including the box.  Here's the link from what place in London, Ontario I bought it from:
