I bought a Remington 600 in .243 awhile back. It has a Redfield "Widefield" on it as well. It seems to be a well made and clear scope, I will replace it with a Leupold I have lying around.I remember them! I bought a 1960's era Remington Model 600 in 6.5 mm Remington Magnum and it came with a 1 3/4 - 5 Redfield Widefield. I have that stored for if I ever market the rifle, but replaced it with a Leupold VX3 2.5-8 as I had plans and have hunted with it.
The Redfield worked fine and my replacing it was only because I wanted more magnification.
