Paintball

[codymm1014]

His is a Sanchez pump kit. I had one on a regular 2k+ sniper and really liked it.

I put my SM kit on (the delrin, single arm). It is not any smoother than my garage-box pump, but it looks a whole lot better.

I also put in some maddman springs. During testing I noticed that I don't get any blow back in the feed neck now. Apparently, having the barrel fit all the way in helps that. When I replaced the bolt orings, a ball left in the feed neck went from a three foot jump to an eight inch jump. Now, after rethreading the body so that the barrel will screw all the way in, the ball doesn't move at all. I guess that was some of my consistency problem as well.

Putting air in the same place every time is most helpful.

I got one of these sitting in a box.. so quick question? so i looked at the CCM 2K mini pump kit and seems like its about 150$, If i plug the LPR hole can i use a standard 2k kit? or does it have to be a specific one?

The mini pump kits have a shorter pump rod and an air-thru block-screw/pump-guide. The extra $ in the mini kits is usually in the ASA or front block and the pump guide with the extra machining. The CCM kits also have good rod guides which you don't get on most other kits.

The SM and Trinity / I&I knock-off kits (~$40) are the pump, guide, and pump rod. Some have mini ASAs. CCM might have one without the ASA (economy version iirc).

It's hard to buy a pump kit that costs more than the marker, isn't it?

.

what did you use to retap the barrel is it just a common tap that you use? the freak back for mine doesnt seat fully on the one i just picked up

I went to Air Soldier Products and bought the import autococker tap. Since most of the threads were already there, and I only have one or two other projects I might use it on, I didn't need the good one. I checked out the thread specs on both at the time and I managed to find the tolerance on the import in my favor due to the barrels I was using at the time, but I don't exactly remember that discussion with myself at the moment.

I discovered last week that I now have NO feed neck blow by, now that the barrel is seated properly. Between the bolt orings and the barrel, a ball in the feed neck would pop up three feet in the air. Changing the orings got it down to about 6 to 8 inches. With the barrel seated right, it doesn't even move.

I have to admit that it doesn't look like my direct flatline arrangement is going to work. No matter what I try, I can't get the flatline reg to work consistently at 400 psi.

any chance you wanna sell that tap now that you're done with it? or do you stll have more projects to use it on?

I probably should sell it. It's actually a pretty good tool for an import. I've seen some imported pipe threader inserts that were just silly and completely useless.

I should be able to figure out if I need it any more by this Wednesday.

I'm pretty sure I will need this tap. I think I found something I can make a barrel breach out of.

I was thinking about shipping it to you and getting you to ship it back, but that's not much cheaper than just getting one in the first place.

As far as barrel seating goes, both Railgun and I had some issues with the little shoulder hitting fatter barrels, but even after you take that off, the barrel wouldn't seat. It looks like they indexed the thread depth from that lip instead of the top side of the opening.

I put an old detonator reg on my front block and dropped the springs down. It seems to be controllable now. The flatline would work for a while, then start sticking or bleeding by. It did not like 400 psi, even with a standard mag spring pack.

Now I'm off to find a brass bushing to go in my front block for the pump rod.

No worries, i'll poke around locally and see if anyone has one i can borrow, i was looking at that stupid little shoulder which will probably give me issues as well since my freak back is bigger
*edit* worst case scenario theres 15/16-20 bottoming taps on ebay i can get for 20 USD shipped
