Doesn't last as long as CO2
O-rings damaged easily
So, I bought myself a brand new Ninja 62/3000 tank as an upgrade from my 9ozs (skipped larger CO2 and went straight to the good stuff) when I bought my 2k0 Cocker. It has served me well through many battles. Now, on to the review:
This wasn't really a determining factor in my purchase, but it is an added bonus. It looks nice, with a Ninja logo on the side and a small gauge that doesn't hang up on things when you slide or dive. It's shaped ergonomically, too, so it tucks nicely into your shoulder.
HPA tanks aren't cheap. This one ran me about $65 plus shipping, so it was on the lower end. It also is only a 3000psi (that's what my field will fill to, and at tournaments I have free air, so I don't need a 4500.), so it was a lot cheaper to buy.
This thing is a brick. It weighs about 4 pounds (by my scale) and causes my drop-forwards to flex when I run.
Fantastic product from Ninja. I would definitely buy another one (and I may if I get into serious tournament play.
Buy it. Whether you get a 4500 or a 3000, large or small, Ninja will not let you down!
