I have a long range target 8.5-25 that i have used in SIgnature Zee rings for about 8 1000yd matches with the leupold target dot. It is in like new shape, but after looking thru a duplex of the same configuration i decided i like the leup duplex better thatn the dot. Im looking for a straight trade on a NIB 8.5-25LRT Duplex(#51606) (since the dot costs more). I'll say it again, this scope is in perfect condition. I will send pics to anyone that is interested in a swap. I'll consider a used, like new scope also.
A other possible alternative is to send it to Leupold and have them change the reticle to duplex for you, costs about 75-100 bucks. If you cant find someone to trade with.
