    Posted: 23 November 2011 at 12:09pm
98 custom act

Setup-
Pmi pure energy hpa tank (48/3000)
Cyclone feed w/ lapco posi feed paddles
Custom bulp loader
14" lapco barrel

Polished internals
Tech-t zero kick hammer with stiffer rear spring.
Maddog pro seal aluminum fire tube
Delprin starfire front bolt.

Problem-
Had a low velosity isuue that was solved by changing out to a stiffer rear spring,
But I've had an ongoing problem of velocity dropping when rapid firing, if I chrono in at 280-290 fps , after every shot It drops about 10-25 fps. I figure it must be a problem with a) my tank. B) my line. Or c) the gun itself not homding pressure.
Bought a different remote line, tried a different tank, and have no leaks that I can hear. I've been told a few different things to try but need someones opinion who knows tippmanns so I figured I'd try here. Do I need a regulator? Or is that only to decrease my psi output of the tank for lower pressure setups? Someone please help!

If you are getting shot drop off in rapid fire you are having a problem with a restricted gas flow.  In other words, gas is not recharging the valve chamber fast enough to keep up with your rate of fire.
You need to isolate the problem.  I would be suspicious of the remote line first.  These have been known to restrict flow rates.

Try backing the handle on the remote off a bit.  Some of these can actually be screwed down to the point that they interfere with airflow by blocking the opening in the tank valve.

If that doesn't help, try the tank directly on the marker to see if the remote line itself is restricting air flow.


Slightly off-topic:  I've heard good things about the zero kick hammer but most other after-market parts (like the bolt and power tube) provide no advantage over stock parts and some have been known to cause problems.  In most cases, original Tippmann parts are the best parts to have in Tippmanns.

Ahahhaa wooooow I actually was just messin around with my marker and took it completely apart down to the valve right out, checked everything for cracks and re-oiled it all, as I put it together and screwed my remote line adapter back on I realized that yes it does press right against the inlet hole one the asa. Thought to myself, I should try to unscrew it just a tad bit and see if it helps. Then I come on here and u suggest the same thing. After all these headaches I truly hope this is the problem :) thanks for all the advice.

I ran into this problem back when I used remotes on a regular basis. 

One easy solution is to completely remove the handle.* Take it to the hardware store and buy a few metal washers that will go around the threaded parts.  Use them as spacers when you put it back together.  It may take some experimentation but you should be able to work out what the right number of washers is that will allow you to tighten the handle down far enough to open the valve but not so far that it blocks the opening.

*Assuming the handle is removable.

What Mack said. I used to put a few orings on my
Older remotes. But I have yet to run into this issue on my Tippmann Connex line nor my PsiWorxs pro connect3.
