ULT Valve Machining, aftermarket trigger questions

[pump]

This lower stop is not set tight, the trigger will travel past the point of firing by a bunch but that last little bit of travel that it does cut out makes it trouble some to remove the valve. This seems to be the trade off for taking out that last bit of travel?

yes

The trigger feel wise is much better, but the force required to pull it is still as stiff as ever. I just have it on a 650 psi tank for a few tests and adjusting (the 900 is empty) I can feel the rod pushing the trigger back once its fired though even on the 650 tank. I read here that as the tank pressure goes up the trigger gets even stiffer but the RT effect is stronger? If so I think I will look into the ULT on off and the required machining for sure. I want a lighter trigger pull not a stiffer one.

The trigger return force is affected by the pressure output of the tank, but the trigger pull force is only affected by the chamber pressure. The chamber pressure is constant, no matter what tank you are using. The ULT has a 4X lighter trigger pull than the standard RT on-off.

if you want a super light trigger pull and to be able to achieve high rates of fire a pneumag mod might suit your needs. AS for the stops making it hard to remove the valve. I always just used a small allen wrench to push the trigger rod in far enough to reset the on/off when i was trying to break mine down. The limited trigger travel is definitely worth the trade off.

Also welcome to the addiction.
