I have a very nice Underwood but there is a hairline starting to develop. So to save the original stock, I've been looking at replacements. They have to be Walnut. Have you ever had any experience with CMP? Here is their website: Sales - Stock Sets The other comes from Numrich. If you read their description, you're almost sold by the way they use exacting CNC and laser testing.

I've never replaced an M1 carbine stock, but the reason I want a newly made one, is that I shoot my Carbines.
