I'm starting to build my first SR character using SR4 rules, and I came across something I can't figure out.
According to pg 322 of SR4A, "Imaging scopes can be upgraded with any of the vision enhancements noted on pg 333."
When I go to pg. 333, it says, "Each enhancement costs 1 Capacity." However, I cannot find what the Capacity rating of a weapon-mounted imaging scope is. Does this mean I can take only one enhancement per scope, or does it mean I can take as many enhancements on the scope as I can afford to pay for?
Also, if I don't take ANY enhancements on the scope, is it effectively worthless? Since the item description doesn't mention it having any inherent vision enhancements, it sounds like a scope is basically an empty metal tube until you give it a vision enhancement.
