I sent my TGI-imported PSL receiver to a machinist to have the scope rail milled.
He returned it without the work being done. Said the receiver would flex too much for the rail to be milled.
A dovetail file, or a triangular file with one side ground smooth will get the job done, albeit slowly.
I have a daughter. I tell her, "911 is what you dial after you're raped. 1911 is what you should have before they try."
There was a post thread a while back where a member made a jig to do the scope rail millling. He bolted the entire receiver, with only the front & rear trunnion installed to the mill table & trued up the scope rail with a 30 degree dovetailed millend. He also did the upper rails in another operation to correct all the problems on the receiver. For the life of me, I can't remember where I saw this.
