sig romeo 1 reflex red dot sight

Hi, selling this used Sig Sauer Romeo 1 red dot sight.  The sight was sitting on top of a different sight, and doesn't appear have been used much.  seems to be in excellent condition, glass looks perfect, only wear I can see is the battery cap screw slot, and it is pretty minor, the 2 screws for mounting the sight are included, they have Loctite on them. The sight auto turns off and then turns on again when it detects movement.  Comes with the small protective cap.

I am asking $450 for a local deal in southern Manitoba, add $20 and I'll ship anywhere in Canada
