I have a Christensen Arms BA Tactical SA stock that has been glass bedded and milled out for the Magpul bottom metal. The milling wasn't perfect as you can see in pictures, but it feeds and runs perfect! Holds the mag super tight unlike the Christensen bottom metal. Even though it is glass bedded I have dropped two different actions in this stock, and they have fit perfectly. The stock with the bottom metal weighs 3lbs 11oz. I am selling it to get something just a little bit lighter. Price is $550 shipped. PM with any questions or offers. Thanks for looking!
