IIRC its a 46 rear and a #55 front base... The trouble is those scopes are too short (OAL) for the two piece bases and LO rings... If you go with a one piece, its higher as you need room to load/unload so that base is thicker... Cannot use Offset rings if you want it lo as they are only available tall...Used to be able to get them in medium.
I have a 3x9 Leupold in Redfield two piece bases and Burris ULTRA lo rings as well as a Bueller swing safety on one of my Mauser's, and that works just fine. This same setup also had a Bushnell 3200 2x7 in years past and it too was fine, but you had to creep a bit on the stock as there was no room between the rings to move the scope. Even with my 3x9 Leupold, I would like it back a bit further. I have the two piece weavers on another in LO PRW rings and a VX III Leopold and a side safety. This one could be a bit lower, but the bolt is fairly close to the ocular lens, so I don't know how much lower it could go.
