For those looking for the Model 71 Win bolt peep, they are rare. I know where one is but the owner wants about $450 for it with shipping.

Alternatively, the Italian Pedersoli company has a reproduction M-71 bolt peep- No.USA- 418 sight that is relatively well made. They have them for less than $150 each including shipping.
Try the Taylor-Pedersoli Company in Winchester, VA.
The bolt peep was made for the M-64/M-71 Winchester rifles.
