Hi,
First post here. I know this reply might be a little late but have you considered the Choate Tactical stock? They have many to choose from, incl.
stocks for the center feed accutrigger, DBM's, etc., available in diff. stages. I think they are aluminum bedding, Harris bi-pod rail w/adapter, etc.
These might be a little on the heavy side but I guess it depends largely on what your intended use might be. Should be good for bench/load development,
prone style ground hog poppin', long shot yote' bustin.
