Thanks for your review of the Sightron scopes, now that there coming out with the zero stop it looks really good. I saw a good picture of it on another site. Stop looks a lot like a screw collar on a reloading die. Set your zero and then screw the stop up against the turret and tighten the set screw in the collar.sightron 6x24x50. they are great scopes and very clear. I now have 5 of them. by looking around and not getting in a hurry I got them all for $600 each. I live in Oregon and leupolds are junk and on there new ones we cant get them to track right and at low light you cant see very good with them if at all. no problems with sightrons.
