.32 Zastava m70 rear sight

[lee n. field]

My son just got himself, sight unseen, a milsurp Zastava M70, a Tokarev-ish pocket gun in .32 Auto.

Anyway, per him

Some scuffs of the grips but otherwise seems in a nice condition. Unfortunately mine came from one of the importers that's refurbing them with disgusting plastic rear sights that are about twice as high as they should be.

I'm guessing it's a kludge added for the ATF sporting purposes test. He says the original rear sight is not in the box.

Anyone have a clue where to get the proper rear sight blade for this? Will a Tokarev rear fit?
