Both rifles serve it's own purpose to be sure to choose the right gun for the right job. Airsoft guns have a pretty limited range, but in tight indoor spaces, a CQB specific airsoft gun will do wonders. Outside on the field, a longer barrel will give you increased FPS and greater accuracy at a longer distance.
