My first R700 308 (5R) went into an AICS. For my SPS Tac, I decided to make it a budget midrange gun and in doing so selected the Choate over the B&C A2. Glad I did. Nice heft without being overweight. Very solid with a nice meaty vertical grip angle. I just installed the Choate monopod, which is a good deal at $25. The gun shoots 0.5-0.7 MOA consistently in this stock, so it works fine. With the varmint barrel profile, the channel does get a little close to the underside of the bbl, but as long as you don't place excessive pressure on top of the stock with hard support underneath the fore end (i.e. bipod), you should be able to avoid contact.
Can't go wrong with this stock at this price.
