If you own lets say a certain 5 OPs then you would get a +5 bonus all the time to ummm rifle combat...you would get no added bonus for being in the actual OP zone....lets say you owned 3 sets of 5 OPs...then you would get a +5 rc, +5 hc, and +5 pc...this way you would only benefit +5 on the character your playing since most characters are not pistol/rifle hybrids.

PS Torg I always ignore what you say because your terrible at nc =)
