Honestly the 13/30's are way too small for my liking. The best size tank for any application in my opinion is a 45/45.

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.

you need better tuning, 200 shots with a nelson from a 13 ci isnt that hard to get.

whats the best results as far as shot counts anyone has got from a sniper with one of these? i'm thinking about getting one soon for mine
