I'm not sure about using a Redfield with a military stock, as the side plate is exposed... but with regard to some of the sporter stocks out there (including my own), the wood must be cut out for the bottom of the mounting base and lower elevation slide.  I have attached a picture of a Redfield 102 on my sporter and you can see how the wood is removed to allow for the sight.  I have since replaced this sight and now have a proper Krag 1902 rear sight.
