RAS rails are generally free floating. They do not mount to the barrel at the far end. In real steel, this means that flexing the RAS by hauling on a vert grip or resting on a bipod does not affect the barrel. Essentially you can handle the gun without deflecting the barrel and affecting impact point. The barrel is also allowed to flex freely while firing.

RIS rails attach at the rear to the rec'r and at the front to the barrel. In airsoft, this means that the far end of the barrel is supported by the RIS. I'd say that this is a better setup for airsoft with it's generally flaccid construction (relative to real steel). We also have no barrel whip issues when firing low energy projectiles.

CA M15 rec'r threading is not standard with the TM threading. You can only mount CA RIS/RAS setups to CA guns. This also means that CA RIS/RAS mountings for the M15 are not cross compatible with TM or TM clones.
