No problem B.H.E.. I have a old Tasco that been around since Mobey Dick was a minnow.It hasn't been on a rifle for years.It never did give me a problem way back.We were doing a job at the Tasco's facility. While I was working there I had them go through it and replace all the seals. Fringe benefit I guess you could say. The reason I said almost ashamed to admit having a Tasco is all I've heard about the newer Tasco's has been negitive.Before all I would buy were Redfields. After they went belly up I switched to Leupolds.This World Class might turn out to be a decent scope I don't know.It's clear enough. Nothing ventured nothing gained.I'll give it a try.For what I got that Knight Disc rifle for with this scope I sure don't have much in this scope.Thanks for your concern.
Ruger Redhawk
