You got screwed by a gun hack!
Good gunsmiths are hard to find.
I wanted my Gander mtn. gunsmith to install a peep site on my 92. (drill and tap two holes)
He told me it would be 6-8 weeks before it would be done at the price of $48.00!!!!
So I ordered the tap and die from Brownells along with the drill bits for less than 48.00 and got them and had the job done in less than a week from placeing the order.
Did the job myself and still have the tap and dies along with the drill bits!
I don't consider myself a gunsmith though,
Just your everyday parts replacer
Did you ever think of just ordering the sights you want and installing them yourself?
It would be the easiest and fastest way.
BTW- If it was me ,I would post this guys name and tell EVERYONE my dealings with him!
