Good find Englander. I have an Ashley peep mounted on my 356 Big Bore. It fits perfectly in the holes on top of the receiver, straddling the bolt in the angle-eject. Winchester had not put a finer finish on a production lever action for a long time till this one came out. However, you will find the sharp checkering on the forearm to be rather unpleasant when shooting full-house 220 grain loads. Sort of like running your hand over a wood rapse! Great rifle.
