*Pure Energy 72/3000 - Very Heavy, that's what made me look into a CF tank.
*Halo B w/ Rip Drive
*CP Clamping Feedneck
*Custom Empire Grips
*Guerilla Air 68/4500 HPA Carbon Fiber Tank
* WEIGHT (or lack of it)
None so far
The only other other tank i have ever used is a 68/3000 regular tank. It weighed 5 pounds as compared to this tank which only ways 2. This tank is by far the lightest tank that I have ever felt or tried out in my life. Also, it is very small and holds a lot of air. What other air system will let you get about 1200 shots per fill and weight 2 lbs. None. The price of this tank is also very good compared to other tanks. I bought this tank for about 150 from Zephyr Paintball and it was a great deal.
If your in the market for a carbon fiber tank, definitely get this one. Great bang for your buck and is very light.
