Spencer, I said mount AND scope. Good luck findin a PE Mount/scope combo for "a lot less than that"
A quick serch on the bay show most PE mounts selling for $199 USD. with c. $25 shipping charges. Some are selling for less, but are live auctions, not "buy it now" items. Who knows what price they'll end at, but I'm guessing $150+.
I only see one PE scope on there. It's $675 by itself.
If you are talking about mounting any old modern scope on a $200 repro base, I would suggest you will actually be taking an M39 that currently sells for something like $350-500 in Canada and turning it into a $100 deer rifle with a $200 scope base on it.
Bear in mind also, that they are 26mm rings and MAY not snugly fit after-market scopes very well. Also bear in mind that you need special screws with taper-based heads to mount those PE receiver mounts. The screws are sold separately and add to the cost.
