Presumably they do. But I'd try shooting it first to see how it handles. My No.4 T has 0.016 gap between the fore-end and butt socket, but I can put 10 shots into a 1.5in group at 100 yards. Eliminating that gap might tighten up the group, but I've never attempted it before and would rather do my first one on a less expensive and poorer shooting rifle.
