Unertl sniper scope
If I had to do it over again, I think I would lay out the 20 bucks or so for 10 feet of some of the 0005 or 0015 tungsten wire that a guy sells on Ebay.
I thought perhaps color of the material might be an issue, but appeared black like I wanted just one of those mysteries. Still is in place, so cannot complain too much. Finally I noticed an old pair of dress socks with some of the fine elastic hanging out, that stretched across the screws worked nicely, not a true fine but a long ways from a medium crosshair. I tried a lot of things, all were way, way too big. I used a human hair, and once in place, the crosshair looked like two telephone poles. So as usual in most things first time around, I did not know what to use for the reticle material. Getting a Unertl Prism marked USMC SNIPER is the scope to find, but good luck doing so legally, getting a USO one marked USMC SNIPER is just as good if you ask me as many saw service, any thing else an homage to the life of John Unertl and is nothing more than a 700 scope being sold to capitalize on the Unertl Name but never saw any service. Four screws and some fine wire, mine was just a crosshair type, not a dot etc. So I took the rear of the scope apart and removed the part that houses the reticle. I was always afraid of loosing the anti-fog charge, but then a more enlightened guy told me not to worry about such, guess they never had any in some of their scopes. I bought an old Unertl scope that had a drooping horizontal wire in the reticle.
