Im sorry if you feel disparaged, Brent. I think I meant to say the rib at the muzzle will be lower than the most superior aspect of the barrels (since the beads are really only superfluous anyway....competition shooters sometimes throw the beads away so their eyes wont be temped to look there instead of at the target). Look again at your English guns and you may likely notice the rib is lower at the muzzle. Im sorry if I confused you but I think this is right (although Im certainly capable of being wrong at times). If Im wrong on this, someone will be by in short order to correct me, just like you attempted to do.
