Tasco Pro-Point 1

FOR SALE:

Vintage Tasco Pro-Point red dot sight.  Includes 30mm red dot, lens covers, rings, sunshade extension, adjustable polarizing filter, display box, manual. Very nice condition.  I'm not even sure if this sight was ever mounted. 

Takes obsolete mercury RM640 batteries.  Apparently a modern substitute is available but I've never used this sight. I tried a pair of common cheap AG13 batteries and they can be used with shims but I couldn't get the dot to dim. But the dot intensity was fine when I took the sight outdoors to test.  

$80 plus $20 shipping
