I will preface this post with the fact that I have never re-joined a lockfast action. From examining photos it appears that the eccentric cam pushes the barrels back against the breech face and locks them into the slot under the standing breech and the cylindrical protrusions of the breech face. It helps to smoke the parts together a try paper shims to determine the area of wear, I would suspect the cam and its mating surface. In times past Tig welding or piecing in a new bit of steel would have been done, today micro welding is likely the best bet.

Can you give more details on the polygon rifling? The Brits used a variety of systems to rifle a barrel.
