You'd be well served to go see Aaron Roberts,at Roberts Precision Rifles, right around the corner from MG Arms. He is the finest gunsmith that I have worked with, and his work is exceptional. He'll build you a rifle that will be EXACTLY what you want, and it will be generational....
I agree, Aaron Roberts is a top notch rifle builder and I would contact him in regard to your needs. A great guy to do business with.
