The Redfield of today has no resemblence to the old 'original' Redfield scope. Redfield manufactured a top of the line series of hunting , target, and yes, even tactical scopes when they were located on Jewell Ave. in Denver.
There was some kind of chemical pollution mess that took place on Redfield's old site, and it seems that it was so serious that the company went under. Their name, and probably some remaining inventory was purchased by that big fish (that eats little fish) company named Blount, in case you want to know why RCBS went to hell!
Blount now imports scopes made in Asia under the Redfield name, much as Tasco contracted their crap out to some third-world country. The only thing that the presently manufactured Redfield scope has in common with the great old Redfield scopes is the name.
A few facts - Don (I think) Burris, who started the scope manufacturing company in Greely, Colorado that bears his name was a high level executive with the old Redfield Company before he went out on his own. The first issue scope for the USMC M40 sniper rifle was the Redfield 3-9X Accurange. The Redfield 3200 and 6400 series target scopes once held all major benchrest records. Redfield, in its day, sold more top-of-the-line hunting scopes than its competitors combined.
Now, which Redfield are you talking about?
