If you find a factory version with the stock your son likes, and the price is the same or cheaper than getting the base rifle and adding a similar stock, go with factory.

If you can't find a factory version your son likes and want a laminated stock keep an eye on Cray Deals section on the Boyds website. They sell off limited run and factory seconds on here and you can get a great deal. Also sign up for their newsletter, they send out e-mail on a regular basis with a 50% off code on their crazy deals. I picked up a unfinished thumbhole stock for my sons Savage 93 for $35. The stock was a factory second that had a small chip out next to the magwell, sanded right out, then I just finished it with Tru-oil. Check out link below.
