Now that we have a decent understanding of how the trigger interacts with the marker system, let’s look at what the R/T does to enhance that system.


The RT is an air fed solenoid that pushes the trigger back into the forward position during the Re-Cocking phase (step 4) of the cycle. The R/T replaces the single sided banjo fitting that feeds air into the cyclone with a double sided fitting. The second side feeds through a restrictor valve and into the solenoid. When the air enters the solenoid it pushes an arm forward into the back of the trigger. This is a mechanical assist to the trigger spring in returning the trigger to the forward position.

How does this help?

The trigger spring, by it’s placement, naturally forces the trigger into the forward position placing the trigger slider under the nose of the sear. The stronger the spring the faster the trigger will go to it’s forward position, but unfortunately the user has to be able to easily overcome the force of this same spring to pull the trigger back. This limitation forces the weight of the trigger spring to be limited. With the forward trigger assist from the R/T the user no longer has to “think” about releasing the trigger to re-fire as the solenoid does that for them.

What are the specifics to getting the R/T up and running?

Well – as with the rest of the marker, it’s a fine tuned system of sealing air from leaking to the atmosphere and forcing the air where you want it. Following the directions provided with the R/T helps considerably in this process. In other words, before asking why your R/T doesn’t work right try doing the following:

1. Read the frigging manual!
2. As with the rest of your marker, make sure that all of your air sources and o-rings are sealed. If the air leaks the R/T won’t R.
3. Read the frigging manual!

Why use an R/T if there is already a spring to do the work for me?

The R/T enhances the effect of the spring. When it is fine tuned and modded the R/T is easily capable of sustained high rates of fire, but is technically not “automatic” fire. Theoretically you could get the same effect as an RT with a stronger trigger spring, but your finger would tire quickly with trying to massage the trigger into a sweet spot against that much resistance.

Sweet Spot? What’s that!?!

The sweet spot is the exact place in the trigger pull (about ½ way back) where you keep constant pressure on the trigger. The R/T will automatically re-set the trigger for you and your pressure on the trigger only allows it to move a fraction of an inch to fire. Finding the sweet spot on an unmodified R/T is possible, but takes lots of initial practice for most people to find it, and even more practice after that to maintain it past 3 to 5 rounds before over stroking (pulling the trigger to hard) or under stroking (not pulling hard enough).
