I'm not sure, but the Ninjas have always been more comfortable for me. The others' fill nipples always got in the way for me when I used my left hand...
the 13 300 was too short for me so i put an odor eaters foot spray cap (the green lid) on the back snaps right on and a little black tape and it made it longer
and i been mowin faces with it ever since

I just got a 13 cu in for my phantom...works great. It beat playing with the 3.5 co2 that I had. It is on a bottomline asa off the back of the handgrip. Makes it really balanced and works as a stock to line up shots.
Great efficiency got way over 100 shots. Only one weekend of play with it but I REALLY like it.
