Yes I've already sorted that one by wrapping a .010" shim around the muzzle and then putting the stripper on over that. I turned a plastic tool up that fits in the barrel and through the stripper cones to make sure the stripper is central before I nip the grub screws up. It seems very poorly engineered in my opinion as they all seem to be the same!
