Re: Chamber Concentricity
If you want to ship the rifle to a gunsmith then there are
Kirby Allen- APS
Shawn Carlock- DE
Nathan Dagly - SSG
who produce very good rifles.
If you want to drive it to a smith, then there is Eddie Harren between Rockville and Frederick Maryland.
Kevin Cram up above Harrisburg Pa.
Those are the forum sponsors and members who I remember at the moment. If you travel around a lot then there are other options of dropping it off and picking it up.
