Having used these I must say it is a terrific mod.
However it is not remotely walkable. The mod actually makes it less walkable, increasing the pressure required to fire. It is still far less than an RT trigger.
The stock ULT is squishy with an indistinct release due to the lightness. I chuffed on it regularly (short stroked). The modded trigger I could not walk, but was incredibly fast with. It felt light and short but also crisp and responsive. Like the RT on/off but with half the pull and a third the trigger weight.
It is very easy to shoot quickly and properly.
