Does your rifle currently have a drop box? If it does it makes things easier as you already have a reference point.

I have not specifically put in a ptg, but the CDI needs about 0.050" cut on each side. I do mine on a mill, but if you take your time a rotary tool and sand paper should get the job done. I also set my magazines where the feed lips are just below the bolt when the magazine is jammed up as far as it would go.
