88
That is the basic shape the stock comes in there is a lot of wood on the forearm so you can work it pretty much anyway you want. The magazine is a trial and error sort of thing you just have to work with it. The 308 mag is a bit easier to work with than the .303. I drilled out the rivets on the charging clip guide and welded up the receiver on the topside just left the bottom two holes open since they do not show.
Hope that helps.
