IIRC, a scout rifle is not NECESSARILY a bolt action, according to the originator, Col. Cooper. But as a practical matter, for all intents & purposes, a levergun doesn't make weight in any standard config, so a scout rifle (all but) must be a bolt action, without severe modification (lightening cuts or special design of lever or other action). The repeating capability of the levergun does meet the general requirement. But it's the tube mag and hefty receiver that keeps it from making weight. But you're correct of course in saying that a forward-mounted scope does not a scout rifle make. It's one of several features of the scout rifle concept. In any event, I prefer standard scope placement on any rifle which has a scope. But neither a forward mount, nor a peep rear setup, nor a see-through combo of the two are bad things. To each his own. I kinda like the forward mount for a short-range big-bore like .45-70 or .444 marlin. For a .30-30, I'd prefer a traditional scope placement, if scoped.
Question: Do those pictures of leverguns on that XS website, which have both the forward low-mounted scope (non-see-through mounting), AND a ghost ring rear:
-contemplate that the scope dials down to 1x so that you use them co-witnessing, or
-just for show (i.e. a BUIS only)
