Ok, so a few months back I was first playing with my Phantom and the velocity wouldn't go down below 315ish, so I opened it up and clipped a spring.

Then it was a little low. Trying to turn the velocity screw in, I damn near stripped the tool! I used a screwdriver, and it was very hard to turn.

I checked and the nylon set-screw was backed out plenty, so that wasn't holdiong it up.


When I took the bolt out, I had to vice it to be able to turn the velocity screw.

I removed it and it doesn't appear to be cross-threaded, damaged, or anything of the likes. The threads look and feel fine.

But putting it back in I greased the hell out of it, and it made it slightly easier but it went about half a turn ok, and half a turn really hard repeatedly until I bottomed it out.



ANyone else have this problem? Do I need a whole new bolt or will a new screw do the job?
And lastly, where can I get said parts?



I never posted about it before as it is staying at velocity extremely well, but it IS a problem that needs to be remedied.

I know you mentioned it didn't appear to be cross threaded, but it really sounds like it might be the problem. Perhaps just a slight part of one of the threads is bent a little, it might cause some resistance.

Any chance that at some point someone may have put a metal set screw where the nylon one sits? i've heard of some people doing that, but i've always been concerned about it messing with the threads.

If indeed it is, i'd call Mike at CCI and see if you can work something out with him. He is very reasonable and will take any measures to fix it. Call mike and your problem will be remedied.

I had this EXACT problem.

I found out that it was my TPC (tuned-port compensator) which is the velocity adjustment screw. I checked the threads, took pictures for others to see, and re-checked all of it. I found it was weird that the TPC would screw in opposite of how it was supposed to but never the correct way. (still confuses me today)

I did call Mike at CCI and he knew exactly what it was. The start of the threading on the TPC was just a little mashed........totally not obvious to me but once I looked really close I could tell. He said I could try and fix it myself or purchase a new one. I purchased a new one. Im sure he would have taken care of me had I purchased the Phantom from him but I got it from Wevo so I was charged. (dont think it was too much)

He got it to me ASAP and well packaged in a padded envelope.

Call him and let him know whats up, he will DEFINATELY take care of ya.

As UD said, it was just a very slight mash of the threads.......thats all it took to be unable to adjust it anymore.

Mike mentioned to me that you can only turn the TPC so far before it will start to smash the threading. You wont even notice your doing it either.


D~

No, there was never a metal screw there. The guy I got it from bought it new, used it for a month or so, then traded it to me for an Automag.


I will defnitely contact Mike. Thanks for the suggestions.

Phantom

Link to CCI website if you don't have it already.

Got a tap and die set?
I had the same problem you seem to have and was able to fix my TPC myself.
the threads in question are 1/2"-20

I do not, but I'm 99% sure my uncle does along with all the tools he has leftover from when my family ran a repair business.

I'll ask him if I can do it.


Just thread the TPC into the die?

You ever get this sorted out?

The answer is "yes" you just thread the TPC into the die but MAKE SURE you have the correct threaded die! You're looking to clean up the threads, not cut different ones. ;)

Thank you for the info, I can fix some of my friends gear now.

Nah.

It actually holds snug in the correct veocity so I never actually went and fixed it.

Its a bit late now, though, as I sold the Phantom. I'll be shipping it out tomorow and using the money to buy a Ghost from somewhere...

I fixed a friends TPC and bolt this morning, the 1/2- 20 NC was correct.

Since it wasnt specialized equipment that cost a ton ill try to fix TPCs and bolts for shipping cost, No guarantee on them but its worth a shot.
