The Boyd's stocks are routed to take the factory bottom metal (Detachable Magazine), so that will be something you will have to find if you do not have it. Another thing with them, they will have to be bedded if you want to get consistent accuracy since they are nothing more then laminated wood and have no pillars.
For about 150$ more, you can get a KRG Bravo and not worry about getting a bottom metal piece if you do not have it.
