I am curious, has anyone tried the Leapers Accushot 1-Pc Bi-directional Offset Mount? I was thinking of picking one up from pyramid along with a leapers 3-9X32 full size scope. Seems like it would work well on the B3 as I noticed you have to be careful with the one piece mounts, they are kind of long as the rail is less than 10cm, but the offset mount is shorter. Would even have room for a stop or level. (I think mounting rail on B3, at least my B3-3, is just shy of 10cm which is the length of most of the other one piece mounts.) Check the leapers website for the exact dimensions, their catalog has some nice diagrams.
