I used to use Co2, but have upgraded to PMI Nitrogen
A 98 Custom with a 14 in. DYE Xcel, Dead on Paintball Pro Style drop forward, 32 Degrees Hyperstar Bolt, and 48 cu in. 3000 PSI Compressed Air Bottle
-Little drop off!
-Easy to refill
-A little heavy
This is a great product. I recently used it for the first time and saw the difference. There is VERY LITTLE DROP OFF over long distances, and it even improved my accuracy. The biggest flaw is that it is a little heavy, but does not effect the performance. I recommend upgrading to any nitrogen system, but this is the cheapest, best one out there for first time up-graders. I got tired of putting liquid Co2 into my gun because it rusted some of my internals. Also, the consistency of Co2 sucks. Get more years out of your gun by putting a cleaner air source through it, and you will watch the opposition cower in fear. Before upgrading to this PMI 3000 psi 48 cu in. I really didn't think it would enhance the performance of my gun that much. Wrong indeed I was. If you're looking for an upgrade, I very strongly recommend this one. To search for the cheapest prices online, check ebay. People sell these things new for dirt cheap and even sometimes with free shipping. Look into purchasing nitrogen, and not only benefiting yourself, but the health of your gun.
For your next upgrade, purchase this tank. Demonstrates clean, efficient, consistent use and comes with a gauge.
im thinking,is hpa really cleaner.
consider the factors
in your hpa tank is a mixture of this(seriously it is)
etc on elements
nuclear waste from chernobyl(yes its true its everywhere)
gassess from coal power plants
co2(yes it naturally occours in our atmosphere,imagine that)
water(causes rust with the oxygen mixed,i mean humidity here)
fumes from glues solvents etc
