"I heard it didn't work in ICS I put it in my Car-97 split gearbox M-16 sniper rifle, and it worked perfect. not sure what the standard ICS gearbox differance is.

(bought it for my Echo 1 because I bought a metal body and head to get a now hopup to work with it. just swappin parts to see why it wasn't compatable with ICS)

WORKS ON ICS CAR 97 split gearbox!

I havn't used many other hopups so I don't have much to compare to, but had major improvement over stock hopup!
