I have a crossbow scope for sale, made by tenpoint. It's a zero power, 40mm multi-dot scope with an integrated, 7/8-inch mounting system that requires no rings. Its three illuminated dots, calibrated for 20, 30 and 40-yards, can be rendered in red or green to suit individual hunting and light conditions. The light intensity of both color views is regulated by a five-position rheostat. $75.00 OBO free shipping Have paypal it is this same scope as this one http://www.tacticalandhuntinggear.net/pd_tenpoint_crossbow_40mm_multi_dot_red_dot_scope.cfm
