Well I just restocked a 700. Benefits, how about because you want to? Or because you hate that dang ugly factory stock. I hated the 700BDL stock, and I put on a beautiful piece of walnut, with not monte carlo or a shine you can see 100 yards away.
Not sure what you want to do. If you are the X gen, I have do doubt you are looking for a piece of plastic to put on it. More details.
