Paintball

[rnm410]

I seem to chop when I put my ULE trigger in. It is usually coupled with a short stroke, something I never experience when I put the stock on/off in my X-valve. Anyone else experience this or have any suggestions?

Level ten is tuned, I'd say perfectly. ULT is at max shims that fit. No runaway.

most likely because you are short-stroking it.
If the lvl10 is tuned well, it's probably not chopping. When it chuffs from short-stroking, it's using just enough air to push the ball in the barrel and let another drop into the breach. next shot after that, *POW*, paint everywhere

how to fix this?
I'm sure others have a lot more insight than me since I generally don't like using the ULT. Trigger stops will help a little.
You pretty much need to learn to pull the trigger all the way back and release. Keep practicing that and it'll become second nature and you're firing speed will pick up too.

It's hard to beat a chuff, ever. Chuffs are from when you don't let off the trigger enough and/or the on/off doesn't reset enough between shots. You get enough air to push a ball into the barrel where it waits for the next one to come along.

There's a few things to try.

1) oil the ULE on/off pin directly. This helps for a while, or at least lets you know if that little o-ring inside is the problem (sticking).

2) use a high output bottle. A fast crossfire is minimum, a 950 or more ninja will kick the on/off out more.

3) polish any marks off the top of the sear and the bottom of the on/off pin where they meet. This has been worth about a 0.005" shim for me. With a dremel and polishing compound they will mirror up. Leave a little grease there.

4) light oil on the sear pin, don't leave it dry.

5) play light on the trigger. Better to miss a shot from too light than too heavy.

Basically, tune and play it like you want it to be reactive.
