I bought my first Weaver in 1966, a K-4, I still have it and it's still putting venison in the freezer. Since then I've put a K-2.5, a K-3's, a K-6, a V-4.5, and a V-10 on rifles from .218 Bee to .358 N. Mag and haven't been able to break one yet. Only the K-6 on a custom 722/257 Robt. has departed. These scopes have ridden alot of different rifles, I sell or trade the guns but keep the scopes. I'm looking forward to trying a new V-7.
