Redfield, as a U.S. riflescope manufacturer, went away in 1998. But Leupold, the premiere U.S. riflescope maker, bought the name and the rights--and is now making Redfield riflescopes in Beaverton, Oregon, as sort of a feature-reduced, mass market version of the Leupold scopes--and at very reasonable prices, cheap enough to compete with the Chinese optics, and certainly better made. This is very attractive. Leupold has a spectacular reputation for the optical quality and mechanical durability of its products (which is why you find a lot of their high end stuff in use by the U.S. military).
When I was a gun dealer, I once sold a very high end combo--a Browning A-Bolt Stainless Stalker rifle with a Leupold scope on it. The scope wasn't much less expensive than the rifle--and both the rifle and the scope were exquisite works of art. There may be a Redfield like this in my future.
