This is an easy one:

Leupold 4.5x14x50 Matte

After 42 years of hunting I nor anyone I have ever known has ever had to send one back for repairs.Lifetime warranty.Not many companies will replace a scope -questions unasked.
One thing about a Leupold-you dont eevn have to be the original owner to warranty ot replacement of any scope.What company does that..thats true confidence in their product.

If your wondering about the power range..

I am x-military..still believe in the old addage-the better you see the better you shoot!!
