I have a few. To begin, the use of the word "System". It is unclear what is meant by that. Is it analogous to a manufacturers line? As in the Glock line of semi-automatic pistols?
Also ... a Swiss rear sight ... Is it the kind with square head adjustment screws for windage and elevation? If so ... why is that worthy of a specific name? When were such sights introduced?
Doubtless more to follow
