The R/T Trigger stop/slop mod

I’m still thinking of a better name for this mod, any and all ideas welcome. I’m hoping for something more venerable and descriptive than “Psyopper’s trigger mod” though it is always cool to have something named after yourself. 

Once again, lets’ recall how the R/T works: It’s an air powered “solenoid” that when you fire the marker an amount of excess air is bled off of the system to feet the solenoid. This solenoid engages the back side of the trigger to force it forward assisting the user in resetting the trigger for re-firing the marker. If you look at the back side of the trigger (opposite where the users finger engages the trigger) you will notice a molded flat spot – this is the “landing zone” for the R/T’s piston. I noticed that there was a sizeable gap between the LZ and the piston when the piston was fully retracted. This gap meant that there was an amount of time (small, but not non-existent) between the time that you pulled the trigger and the time that there was enough air bleed into the solenoid for the piston to hit the LZ and push your trigger forward.

I negated this gap by drill/tapping a 10/32 hole and filling it with a set screw. This set screw should be short enough that you can screw it completely into the trigger so that it’s flush (returning the trigger - R/T interface to stock Tippmann specs) but long enough that you can back it out roughly 1 to 1.5 mm. The end result is that when your trigger and sear mods are complete, when your trigger is fully pulled to the stop and the R/T piston is fully retracted, the set screw is less than 0.25mm (a hairs width) from the face of the R/T piston.


Simple, elegant and kinda cool if I do say so myself…
