I'm playing by a set of rules that specifies that only magazines with a capacity of 80 bb's or lower is allowed. When using MAG magazines there are a "port" in the bottom of the magazin that allows access to the "inner" end of the "spring tube". By putting a certain amount af bb's in there we are able to convert the MAG magazines to 80 bb's capacity. Is there a similar hole/port in this magazine?
