Here in Wisconsin I've heard it referred to as the Pennsylvania set-up I have never used see through mounts because I like my scope to sit as close to the barrel as possible. Mine sports a Leupold 3-9X40 in one-piece Leupold mount and rings. If you buy a new one, do yourself a favor and get two magazines. To sum up what I like about it: uses magazines; free-floated barrel; good backup open sights; weight; ease of cleaning once a year; fast second shot due to familiarity with pump action - hell I don't even notice I rack a new round most of the time; plenty accurate; works when its below freezing out; affordable.
