slatercaller,
That particular Nikon Buckmaster is a new scope and has not been release by Nikon yet. They are looking at somewhere around the end of June the beginning of July. By the specs, it sounds like it is going to be a very nice scope. The 6-18x40 actually has better light transmission than the other buckmaster scopes, 92% verse 88%. I have some catalogs on order and are scheduled to come in today or tomorrow. Once I get them I will let you know on the dot size.
