Yup most of the V2 guns should have the LW ram but it's not needed. Pooty bolt will give you a bit of a velocity boost BUT, you have to have some pretty soft orings on the bolt so they can expand during firing. If they don't, you won't notice much. I was able to get mine to work after going through a lot of orings and testing. In the end all it will give you is maybe another pod of paint at best. Not a game changer.
If the gun is broken in.....it'll work pretty awesome stock.
