Do they offer an inletting service whereby you send in your pattern, already glass bedded for your rife, and they then use your pattern with their wood.
I don't see how they could mill a crooked barrel channel. Sounds to me like they are using wet wood and it warps after inletting.
Kevin, might give 'em a call, I think they do.
