I had a service grade built into a 308 NM M1. The plummer kept the barrel and stock as part of the deal. I went with a heavy stock and barrel. The rifle shot well, but it was expensive to feed even with reloads. I'm in the need of a rebarrel but holding off right now as my tuned AR shoots circles around the old M1 for less money in ammo.
Also be aware if the plummer is any good, you will have a long period of your rifle being away. My M1 was gone for 16 months.
But it is a work of art!
