PP700 adventure started(Artemis PP700s-a)

[Cathartes]

No creep on my reg so far. Reading on the Facebook group, sounds like it's a big problem for those tuned down to 6 FPE, but less noticeable on those tuned higher.

I'm reading bad things about the O-rings. Zo i want to buy better spare one zo i don't have te wait for them when the gun is leaking. I only find O-ring on Ebay.

Are they any good. Or are there better. When i know the sizes i can oder them at work, food grade compound and thuff.

Here is the size list I made from the schematics I got from another source, and I attached the pdf:
PART NO.    SIZEmm     QUANTITY
6                 12x1.5        1*
11                14x1.5        1*
13                16x1.5        2*
24                7x1.5         1*
25                15.5x1.5     2*
31                8x1.5         2*
33               11x1.5        2*
35               27x3.1        2
I ordered a full set from the o-ringstore as well.  They do have minimum quantity requirements, but it still only cost me like $10-11 dollars to order all the ones listed.  I will note that I was unable to find a 27x3.1 o-ring, but I did find a 27x3.  I haven't tried to install it to know if it will work.

Is there a such thing as 1 and 1/16" by 1/8" oring? Maybe that is the 27x3.1? Total guess.

[Rallyshark]

There may be one that size?  I would doubt that Chinese gun was meant to use a non metric o-ring if I were to guess.  It is an odd size though. 

[nervoustrigger]

FYI, the 3.1x27mm isn't called out correctly.  In the spares that come with the gun, there is a 3.1x21.  Its outside diameter is ~27mm but metric O-rings are described by the inside diameter. 

With that said, it doesn't seem to be a standard size based on Marco Rubber's chart:
http://www.marcorubber.com/userAssets/file/size-charts/CommonMetricSizes.pdf

A 3x21mm will surely work.  I suspect a -211 (3.5x27.3mm) in 50 durometer would probably work fine as well.

Anyone know where I can get a 1/2-20 thread adapter for the round shroud mkI?

I thought I had one lined up,that seems to not be working out

I only see the MKII version on Tr Robb..

I found what looks like a slip on version for it, out of stock, no more expected...

Anyway, my MKI from aceros should be here next Wednesday, I'd like to find an adapter soon if possible.

Edit:

Never mind fellas, my first choice option just came thru

Hello to everybody, I need help for my Artemis PP 700 S-A:
Velocity of pellets increas at every shot, (once set at 550 fps start to raise to 800 fps in 30 shots) when I refill the tank when empty , fps are now 450  and start increase again at every shot...

I have already dismantled and cleaned everything, lubricate with silicone grease and I have no leaks

I think the regulator does not work properly , what could you tell me about this issue?

I need to know the exact size of o-rings full set of spares too, could anyone send me please  these infos?

Thank you very much, best regards

[Dairyboy]

Personally sounds like the reg isn't working at all. Sounds like the typical bell curve on an unregulated gun with not enough hammer strike. Since it's supposed to be operating at the lower regulated pressure that explains why it's so low at first

[whisper2]

 I also believe it and agree with you, some suggestion?
I think the fault could be either of the o ring n24 or teflon-delrin ring n28 in the  exploded diagram...

[Rallyshark]

Increase the hammer spring a turn and shoot a few strings.  See if that doesn't make it behave a bit.  Also, you can snug down the reg adjustment screw a bit.  Mine showed up with that pretty loose.  It does take it 150-200 rounds for the regulator to settle down a bit as well.  It is common for the first shot or two after filling to be low.  I usually do 2-3 dry fires after filling myself.

[shultz]

Quick?

My 700w showed up today. So far so good but, I have a slight breech leak. Toilet paper puffs up but doesn't blow off. Anyway, what the best approach to get the breech block a smidge tighter? The breech seal looks good, I don't think it's the problem.

So far the Chrony numbers look ok for out of the box. I don't think the little leak is hurting much, still, I want to eliminate it if I can...

Unfortunately I have already tried several times as suggested and I shot a few hundred shots during the tests, I also realized that after filling the tank the first two shots are low, but then the cycle resumes and the pressure starts to increase as described above.
I also tried the new arrangement of the cup springs inside the regulator as you showed earlier ... nothing to do....

De gas the gun and there is a small set screw that you need to loosen and adjust the face of the valve out to take up clearance for the breech seal, might take 5 mins. David

Thank you David, but as already said I had already dismounted and verified everything, also three hours ago I repeated this intervention by replacing the or ring of the regulator with  a little bit bigger one... I tested the operation of the small screw you talked about by adjusting the space that causes the air passage in the regulator to the minimum and then screwing it and unscrewing it during the test shoots as it has not changed anything.
I also saw with a magnifying lens the contact surfaces of the conical screw seat and its white washer (components 28 and 29 on the exploded diagram) and did not find any defects.
everything works, I have no leaks but the main problem remains.
Ciao.

Thanks David!

I figured that was the how. I wasn't sure about the de gas part. I'll shoot it down to keep breaking in the reg, then de gas and adjust the block a smidge.

For those that may not have a spanner or something to work the valve face/barrel nut.



This tool should work well. 2.3mm pins on it, I measured the holes right at 2.4mm. For now,I'm using a large set of snap ring pliers. The pliers worked fine getting off the barrel nut, still, right tool for the job and all that...

I'll post my results with the park pin wrench once it delivers.

Rallyshark,

Not being able to really tighten the barrel is troubling me. You added a set screw to hold the little breech plug. If you had to do it again, would you?

I nearly drilled and tapped both of my guns for an M3 set screw last night....just want to make sure I'm not making a mistake.

My Airmax PP700SA showed up Tuesday and I've been having a lot of fun with it. I've been getting good velocities right out of the box. I took it out in the woods today with just the open sights and I knew they weren't worth a darned after that episode.  There's no adjustment for elevation at all .  When I got home I mounted a CP 2X pistol scope on it to see just how accurate it is and it's more accurate than I am on the window sill.  I'm not crazy about the scope, I know it's going to take a lot of getting use to but it is more accurate than a red dot (old Barska). I'll be taking it back out in the morning for some more fun.

The instructions that came with it give you no details at all how to make adjustments and I do know that you can adjust about everything on this from what I've seen.  I think it needs to breath better through the transfer port because in the 30 shots it slowly climbs in velocity and shot 29 & 30 you can tell is falling of the reg because by that time it's down to 80 bar.  So far I've got about 150 shots through it.

I absolutely would do it again!  It is easy, and doesn't mess with anything

Pistol scopes do take some getting used to, but once you are, they're great!  The main adjustments you really need to worry about are the reg adjustment(inside the front trigger guard), and the hammer spring(remove the grip).  The reg adjustment is a 4mm allen, and is a little tedious to get to.  I would snug it down just a bit.  You can probably get the velocity you want without opening up the transfer block, and make sure the transfer screw on top of the block isn't screwed down blocking the port some if you're looking for more power.
