Keep in mind that you won't be allowed to play with a hot gun in CQB. Lets say your outdoor gun shoots 385FPS you will not be allowed to use it in CQB unless you either use a velocity reducer or you do a spring change to bring it down to the legal level for indoor play.
If you think you're going to be playing a bit of both (CQB and Outdoors) then might I suggest an ICS gun since spring changes are easier (from what I hear) due to a different design (split mechbox).
