Remington 721 Scope Favorites
Introduced in 1956, the Weaver K4-60B brought constantly centered reticles to the Weaver line. We put this K4 scope on rifles from 1956 to the late 60’s in place of the poorly built 60C through F models. Like all of our restored scopes, it is restored using all original Weaver parts but modern glass, glues, seals, and lubricants. This is the best in the series of the most popular scope ever made!
