Help
First off, heres a definition as to what the ULT is: (Pulled from NinjaoftheNight79's Automag guide)
ULE Trigger Pull Kit
The ULE Trigger Pull Kit (also referred to as the Ultra Light Trigger Pull kit, or ULT) makes the trigger pull lighter. What it does is replace the stock On/Off assembly with a two part ULT On/Off assembly. It is two parts because it too is adjustable with shims (of a different size). This ULT piece, in comparison to the old On/Off, lowers the pressure pushing the pin by making the pin smaller, just as done with the Power Piston on the LVL 10, allowing you to pull the trigger much easier, allowing you to walk or fan the trigger very easily. Just as the LVL 10 needed adjustment, so will the ULE Trigger Pull Kit. You will need to adjust the amount of shims (only use ULE Trigger Pull kit shims unless you know what you are doing!) in order to adjust the length to set it to the right length for it to fire correctly. If there aren’t enough shims, the marker will not fire. If there are too many, it will either double fire or fire full auto. Some people actually do this on purpose, but it is not field legal, and I do not recommend it.
One thing that has been said about this mod is that this also makes the marker capable of being "short stroked". This means that the trigger is not pulled back far enough the marker will either shoot the paintball a very short distance, or not shoot it much at all and leave it in the barrel for the next ball to chop it. This can be a problem. I plan to check on this, but I do believe it is true because it came from Tom Kaye's Prototype page. This could just be a problem with his older prototype, but it was said on the last page where he announced that the ULE Trigger Pull kit would be released soon. He also said that with practice, it would be very easy to walk the trigger without short stroking.
This upgrade will not work on any older valve. It only works on X-Valve and about half of the RT Valves. If you own an RT/ReTro valve, check the RT/ReTro valve section to see if you can use this upgrade or not.
Initial Start: (Things you will need)
1) Small screw driver...you'll see what its for later...
-----------------------------------------------------------------------------------------------------
Step 1:
Remove Back screw and macro-line from valve.
This is what it looks like with the said parts removed:
-----------------------------------------------------------------------------------------------------
Step 2:
Slowly remove X-Valve from mag body, set mag aside.
-----------------------------------------------------------------------------------------------------
Step 3:
The gold object on the underbelly of the X-valve is the On/Off assembley that needs to be removed. Slowly remove it from the valve
The last picture is the stock On/Off assmbley removed from the valve.
-----------------------------------------------------------------------------------------------------
Step 4:
Theres a o-ring thats left inside, it might not come out with the stock on/off. Use the small screw driver I mentioned earlier to remove it. Again, dont rush, do it slowly.
-----------------------------------------------------------------------------------------------------
Step 5:
Get your ULT.
Mine came with 2 shims installed since I bought it used, If you get it new, it might not have any shims installed. Shims are the small silver discs. There should be 8 shims that come with it I believe, mine only came with 7. Below is the ULT disassembled to install shims. To take it apart, simply unscrew it and apply very minimal force to pull the pin out. BE VERY CAREFUL. I cant stress that enough. Take your time.
As you see from the pic above, the shims just sit on the bottom half of the ULT. I installed 4 on mine and it rips for a mag. I can walk the trigger. Ill post a video on it later.
----------------------------------------------------------------------------------------------------
Step 6:
Reinstall ULT. Simply screw the top back on the bottom on the ULT and install it just like you took the old on out. It goes right in.
----------------------------------------------------------------------------------------------------
Thats it! You're done! Now its time to test it.
Air up your mag and take a shot. Immediatly you should see a BIG difference. However, it may need some fine tuning. If your mag is double firing, or full auto firing, remove the ULT and remove 1 shim. Do this until it shoots normally. Some people like to keep it with the full auto effect, however, in the long run this will potentially damage the X-Valve. With a valve that sexy, you dont wanna mess around with it. Like I said, I have 4 shims installed and it rips. However there is 1 thing you must keep in mind. Using the ULT will greatly increase your chance of "short stroking" the trigger. So make sure your fully pulling the trigger back when you're firing. With a little practice, you'll get it!
There you go! Now go out and own some face with your newer, faster AutoMag!!!
