If you are going to shoot it in service rifle, you can get a NM oversize stock that meets the rules and will be quite large compared to a standard stock. Laminate is nice, if you are going to have it bedded try to find one already prepped with the internal oversized routed areas. It may be a good idea to contact a reputable M14armorer to find out what it takes to get it done. Now is a bad time to do this due to everybody wanting to be ready for this years events now.
