PP700 adventure started(Artemis PP700s-a)

I was wrong. Just checked the gauge and it was empty. So I do have a leak someplace. Looks like I'll be tearing it apart again.

If you have a bad tune, your gun will be louder because you are wasting air. Mess around over the chronograph. I can make my gun a lot faster than it is but it gets loud and shot count not worthy. The gun will tell you where it’s running like a clock with a particular pellet. It’s just a matter if you are happy with that velocity.

Good to know. Thanks!

You guys will get a laugh on this one. I think I found out why the gun was so loud. I forgot to put the grub screw in the top of the breech block.

This post made be involuntarily wince, because I have made similar errors that resulted in an underwear check... all good, carry on.

  If it didn't do damage to anything but pride it is all good and a lesson learned. Worse is when you end up with extra parts when you put something back together

I was going to say something isn't right,lol!  If they are loud with David's LDC, then you probably have a leak at the breech block or where it seals against the barrel o-ring   Granted, it has a short barrel, and they can be pretty loud(even with an LDC) when you start cranking the power, but they shouldn't be LOUD.  Let us know what kind speeds you end up making with it when you're done!

I just hope I didn't hurt anything. Plus I have a leak I have to repair.

The two most common I've seen are the o-ring at the fill valve, and leaking where the dual threaded piece fits at the factory regulator(fixed by one of the large thin spare o-rings).  You'll get it up and running

While that screw was out you should have shined a light in the hole and checked to see if your transfer port hole is centered in your barrel. If not, use the tiny screw on the block to control how far the breech block closes. Never in 80 pages did I see this mentioned and I kept forgetting to tell guys. Mine was off.

[Backyard Shootr]

I did put a o-ring in the area where the white disc is also that's why I had the screw out of the block because I was using a pin the size of the port down thru it to make sure that the port was aligned with the block. Well I will check everything out again. News at 11.

The air leak is coming from the notch that I put in the bottom of the air tube. So does that mean the air is leaking by the regulator? Or a faulty regulator?

[Backyard Shootr]

Another Homer Simpson moment?  When I received the Huma it came in a plastic bag with a o-ring around the reg and a spare o-ring in the bag I thought. So I pull the reg to put the spare o-ring on to try to stop the leak. Then I realized the o-ring was smaller than the one around the reg. So I'm thinking and looking at the Huma then it hits me that the smaller o-ring goes between the reg and end cap. There's even a groove in the reg where the o-ring goes. None of the instructions I read mentioned the smaller o-ring. Anyways been a couple of hours and pressure still holding.

One more thing. On a completely empty tank and I start to fill it leaks air out the barrel. I fire a couple shots then it will fill. Need more pressure on the valve spring?

[Pelletjunkie]

That’s a tricky one. I had a similar leak in my Leshiy. Air can leak pass your reg from the air tube. But on my Leshiy it wound up being the o rings inside the reg that let air keep coming out the vent hole on the reg. I found it through a process of elimination. I now have a very very slow leak on my PP700. It’s been apart and filled so many times that I probably just need to replace a bunch of o rings just to be safe.

There is no need to run your valve spring that light. That thing helps control your ES.

Its probably the o ring on your non return valve, on what you can call the gauge block.

It just sounds like your valve hasn't completely seated on the valve seat well yet.  After shooting it, that probably made it seal getting pushed up against the seat hard when the valve closed.  Hopefully, you won't be filling from empty very often, and it won't matter anyway.  It will get better with time after you shoot it more too.  In other words, I wouldn't worry about it

[Backyard Shootr]

Well we have some good news and some bad news. Good news is I woke up and it's still holding pressure. It hasn't drop at all. Bad news it's raining today so I don't get to play with it. I would like to fire a few more shots thru it under full pressure then will chrony it. So my adventure with the PP700 will continue. Happy that I found this thread. Will post my results soon. This is a fun gun.

Here's a picture of it. JSAR carbon fiber shroud, Truglo red dot, Glock rubber grip and MonsterMaxx breech block. Also Rocker1 LDC not in picture. The shroud does lighten up the overall weight of the gun. Will find a smaller red dot to help with the weight also.
