catfishingham, First of all, welcome aboard!!! I use a gunsmith that has an impeccable reputation both as a custom gunsmith and as a person. His Name is Ed Gagnon of Centerville, Mass. Several others here have used him for the critical job of correctly drilling, tapping and affixing a scope rail on a 12 gauge smoothbore or rifled shotgun barrel to properly and safely mount a scope or Red Dot. It is critical work that has to be done properly to be safe, many gunsmiths just turn down the work because of its preciseness, Ed on the other loves precise work and a challenge! I highly recommend him, his prices are reasonable, his work as good as it gets and the turn around time is quite fast, not like the usual 2-4 months of other custom gunsmiths, he is simply a nice christian guy, but at times can sound like the typical grumpy old cape codder, get past that and you will soon realize he has a heart of gold!...He is quite simply put, one of the best around. Ed has many years of expiernece and is a builder of custom 1911's and all sort of shotguns adaptations and alterations, chokes and choke tubes, backboring, relieving the area in front of the chamber (? sorry brain cramp!!). Do a search under his name and you should find other comments and the info you need, if there is anything else I can to to help, just ask....Happy Thanksgiving and good luck....<><.... :grin:
