Screw In Adjustable Tanks?

[~W.!.C.K.E.D~]

Are there any production adjustable screw in tanks?

Nitro duck X-stream, but sometimes it won't adjust to 900PSI output like they claim.

I saw the Nitro Duck iReg's have a 1,000psi piston...

They come standard with a 800PSI piston and you will have to buy a kit with 3 pistons (400-600-1000). I havn't used a I-reg before so i can't comment on thier perfomance.

Center Flag had the 4CE that had changeable Springs and Guerilla air also had one before the Nitro Quacks "I Reg".
