A couple of years ago I purchased a very nice 99 RT in .300 from 99 Guy. (Shoots great!) The rifle came equipped with a Redfield 80 receiver sight. That is the only Redfield 80 I have seen in person on a Model 99 vs. many, many Redfield 70s. Stroebel's book assigns the same value to the 70 and 80. Given that the 70 was made from ~1940 to 1964 (24 years) vs. the 80 from 1957 to 1964 (7 years) and that the 80 was introduced at the time that scopes were becoming more common on sporting rifles, I would think that the 80 would command somewhat of a value premium.

I'd be curious what thoughts you guys might have on the scarcity/value of the Redfield 80. Thanks.
