The 3C sight elevator was used on model 70 rifles with the straight comb stock and the 22G rear spring sight.
Original Winchester sight elevators are in excellent condition with slight bluing edge wear.
Reproduction sight elevators are manufactured by Winchester and are dimensionally identical to the original part. The only notable difference is a satin finish to the bluing, rather than a gloss finish.
