Custom Sonic, Tungsten Hammer, DEZign bolt, STO Ram, 2k2 Sonic LPR, Besales Hollow Point 3-way, FF springs. Glad reg/Conquest. BOA barrel.
To start with, this valve is very smooth. The valve shaft runs very smooth inside the valve body. This is good for consitancy. The RAT valve has an o-ring on the shaft which can slow the valve stem movement down, the RED holds true and doesnt use a o-ring. Easy to install works great (not for you tungsten hammer owners).
Not much. It leaked out of the cup seal the first time I put it in.. its a lil touchy about how clean that seal is.
Great product, but make sure that cup seal is clean! Doesnt include springs I recommend you pick up some Pro-Paintball or Nelson springs.
