I believe the Choate tactical stock is just over 4.5 pounds. Not sure where you got the 7lbs. from. In any case, check out Bell and Carlson for ready made stocks and Stockade, as well, for a cheaper, custom option (then there's always McMillan and Manners, but they aren't exactly cheap). If you have the centerfeed, your action screws should be the 4.4" spacing, so be sure to order accordingly.

Best of luck,
