Selling Redfield Series No. 70 Micrometer Receiver Peep Sight w/Adjusting Knobs & Aperture|Winchester Swap Meet|Forum|Winchester Collector

Don,  if you can read the letter code on the base (it may take a magnifying glass), I’ll look up the application. 

From the concave base it’s for a bolt gun. I thought for a moment I could read a “V” but it could just have been a scratch.

These are precise and beautifully made  sights, as long as you don’t need a quick release staff. The Model 80, its replacement, added that feature. Unfortunately, the 80 has pins where the 70 had screws and, toward the end of production, substituted an aluminum receiver. 

I’m fortunate to have a 70 coded “E” for the Winchester lever actions and have taken it off several 94, 64 and 53 specimens before sending them down the line. Bought it from the late Gary Fellers Decades ago. I prefer it to the Lyman 56 and 66.
