I hope you get a good one. Check AGN for the issues others are having with them, although they do "moderate" some of the negative posts...

Yea, I've seen some of that.  I'm hoping too.  I did let AOA go thru it unlike the one user who was impatient and skipped that part.  With any luck AOA eliminated any hiccups.  fingers crossed...

[SilentMatt]

That's a good idea, but IMO someone shouldn't need to go through a gun of that cost.


Enough talk of that though, let's get back to our China gem!

Mine is in UPS's hands...

[SilentMatt]

My buddy purchased a "stash can" off ebay to use as a moderator. It's a 5"x 1" anodized aluminum cylinder with threaded end caps, for like $5. I can't even touch that price with material costs.
He left it hollow inside except for some felt around the ID, and says it works awesome. He told me the hammer strike and pellet smack are all you hear.
Mine will be here on Wednesday and should be a vast improvement over the Mrodair LDC that doesn't do much.

This is the one I ordered, got mine off Amazon though:

Correction, the container he bought is 4.75x1.75 external, so he has a lot of volume. Now I might have to order a different one.

I don't have creep in mine anymore. I started with a 1000psi charge and screwed the regulator adjuster pretty far in, until it was getting hard to turn. The string was pretty bad and low power, so I began backing it off, and power went up. I kept going until it dropped again, then began adjusting the hammer and transfer port again. Took a few cycles of that to get what I wanted, but when I was done, the reg creep it had out of the box was gone.

Thanks for that advice.  I'll give it a try.  I've tried everything else without success. 

Another reason for breech leakage must be the transfer port screw, especially when screwed in a lot.  The screw is not a very tight fit in mine, so air has to be leaking past those threads.  The grub screw is way too short if you want to screw it in a lot.  I'm going to replace it with a longer allen cap screw, and put some weak thread locker on those threads to seal it.  I tried teflon tape but that did not work well because the screw is too short.  Maybe it will work with a longer screw.

I'm hoping that reducing the transfer port size may make it more consistent and mitigate the "regulator" creep issue somewhat.  I put "regulator" in quotes because it seems to be anything but.  I'm wondering if it would be more consistent without this stinking "regulator".  I'll think twice before buying a gun with a regulator again.

[Cathartes]

Yeah, I've read that regulator is an inaccurate term, anyway, that it should be called a compensator valve, not that any of that means anything to me. I just turn turn any screw that'll turn, lol. Keep in mind, too, I shot through a couple of tins of pellets while tinkering with the gun. I've heard that helps with creep, too, just shooting it a lot.

I would think it would leak around the TP screw, it certainly turns easily, but I can wrap tissue around it without it so much as moving when fired. It would punch a nice clean hole before I tightened the valve body.

[Techie]

Here you go, a finger-turn velocity adjuster.  Took me a total of 10 minutes to find this 6mm cap screw in my bins and cut it to length with a Dremel cutoff wheel.  You can put O-rings around it if you like.

You can use a low-strength threadlocker (applied and dried before assembly) or a short spring around the bolt to keep it in place.

[Techie]

Did you have to remove the hammer to tighten the valve body, or were you able to work around it?

[nervoustrigger]

Regulator creep generally has to do with inconsistencies in the valve seat.  In this case, it's where the little tapered screw seats against the white plastic washer.  The other night I burnished the two surfaces together with some polishing compound to see if that would cure it but I haven't been able to test it yet due to the weather.  Just a reminder that in my case, there was a tiny sliver of metal stuck to the plastic.  I think it had migrated there from somewhere in the air tube because the creeping just started happening recently.
 
And now that I'm thinking about it a bit more, it could also be a result of air finding its way around the washer.  If that is occurring, it could be a little trickier to remedy because of the reason I mentioned previously...that the seal on each side of the washer relies on flat surfaces mating together.  It's easier to get a good seal if there is a ridge in the metal part to focus pressure into the plastic part.  I think that's a key reason Ninja paintball regulators behave more consistently than the others, because the valve seat consists of a plastic ball that seals off against a hollow metal cone.
 
I may be off base on that second part because it would also be likely that the tank would leak down via the threaded connection between the two halves of the regulator.
 
If I figure it out, or if I don't, I'll let you guys know.

ha.

[Techie]

Please do, Jason.  By now you'd think someone had figured it out and come up with a good reliable fix, but I haven't seen it.  I'd be willing to purchase a third-party regulator for it if someone made one and I knew it worked well.

So how do you attach it to the muzzle?

[Techie]

Duplicate for some reason.  No way to delete that I can see.

He doesn't have a lathe so he just drilled a hole with a paddle bit to fit the barrel nut. It fits just like the Mrodair unit, sandwiched between the nut and shroud.

Okay, I drained the tube this evening after work and installed the O-ring in the regulator.  Then got outside and put a few pellets through it, adjusting the reg and hammer spring along the way to bring it up to about 12fpe (.177 cal).  At that point I ran a few shots over the chronograph with maybe 20sec between them and they were all within about 15fps of each other.  Sat the gun down for a few minutes to see if it would creep...and then mother nature gave me the ol' middle finger and opened the sky up.  So I guess I'll find out tomorrow

[SilentMatt]

Did a little tuning this evening, and figured I'd share the results. I started with 150 bar and took 3 shots(the gun has been sitting for a few days), it shot 598, 630, 628 with 16gr JSB's.
reshaped the front half of the poppet and opened the valve spring retaining nut port to .1875, refilled to 150 bar and shot 3 more, 655, 649, 655.
I've never touched the regulator, so figured it was time and tightened it about 1/3 of a turn. Refilled to 150 and it shot a 595(which I expected), so I tightened the hammer spring one full turn and it shot a 720. I backed it off to around 700 and then the thunder storm stole my light. Hopefully tomorrow I can see what kind of string it'll shoot.


I think the Chrony was picking up lightning, it had a random 4 digit number(no decimal) pop up a few times.

Isn't it the lack of light that throws our chrony's off? 

[nervoustrigger]

Okay, well that may have done the trick.

The rain let up for a bit so I set up the chronograph and light and took some quick shots after it has been sitting up for a couple of hours.

The previous 3 shots were:
894
897
896

Then after the 2 hour rain delay, they were:
897
892
898

That's just great but I'm not going to rejoice just yet.  I'll check again tomorrow, hopefully under some natural light.
