The other point I'd like to make is that the vintage sights I bought didn't fit the Browning 71 or 1886 perfectly. I had to have a little metal removed for a proper fit. Either the holes in the receiver for the peep sight are a little lower than the originals or the profile of the top of the receiver is ever so slightly different.
