I've often had problems with the nylon TPC set screw (for velocity adjustment) backing out resulting in the TPC moving from position which leads to inconsistent / weak velocity. I've found a solution to that. I may not be the first on this one, and if not then I apologize, but I've not seen a solution for this to date - so I'll post how I took care of the problem.

I had some old set screws laying around from the years of collecting I've done. I found a 10/32" set screw and cut it with my dremel at just under an 1/8". I had to place the set screw in a small C-clamp to hold the little MF'er in position then took the dremel to it with a cut off wheel. The end product is a little less than 1/8th" long and it screws into the bolt with a 3/32" Allen key BEHIND the nylon set screw that comes with the Phantom.

You set the nylon screw to snug the TPC up and then screw in the steel set screw you just cut with the dremel behind the nylon screw. It effectively locks the nylon screw in place so that it can't "back out" as it tends to normally do. It forces the nylon set screw to maintain constant and consistent drag on the TPC. The TPC will now stay put where you set it until you decide to change it.

So, you set your gun for velocity by adjusting the TPC - and with this mod the SOB will remain where you put it, it will keep consistent and constant drag on the TPC and maintain that set velocity.

Just thought the info might prove useful.

Actually, there is a much, much easier solution. Hans from the now-defunct Siegecraft Paintball (some of you old-timers or Doc's forum denizens may know who I mean) clued me in on this when I ordered a bunch of the set screws and told him that mine kept stripping. Well, more accurately, the hex "head" would round out, so it could no longer be tightened. Here's what you do:

1. Take the bolt out of the gun
2. Fully remove the TPC
3. Thread the nylon set screw in until you just barely see it protruding inside the TPC opening
4. Thread the TPC back in and it will "cut into" the protruding tip of the set screw

I did this on my old VSC about 4 years ago and had to repeat the process once or twice in that time, but never had to replace the set screw. This reminds me that I need to do this on the VSC I go a few weeks back...
