Does anyone know of a gunsmith in MA who does HK trigger housing Clip & Pins? I have a PTR that I'd like to use with an HK trigger housing, but the PTR dimensions are a little off, compared to the HK dimensions. I believe Gartman Arms had a guy, but he apparently closed up shop during Covid. I might be able to do it myself, but I don't really want to ruin a $100 trigger housing experimenting with my dremel. Thanks for any suggestions!
