PP700 adventure started(Artemis PP700s-a)

[darkcharisma]

a plenum it is. the stock plenum is like 3-4cc. so i'll try to double it and up the regulator. install a longer .223 barrel. possibly converting it to 9ci bottle fed...dont know how much of that ill get to finish.

darkcharisma,
what you're doing is way cool — a gauge and a PLENUM in the PP700!
 
Wow, wish I had that kind of technical ability! 👍🏼👍🏼 Looking forward to hear your performance figures!

This should be interesting

I'm interested in a regulator guage just need to locate the hole center. I don't understand the plenum and not sure I even need anything for this gun.

My PP700 is a hoot.

Barrels:
.177 and .22 and both shoot very well

Stock Mods:
Made several rifle "stocks" for it and for now stopped at one that connects to an L-shaped block that has two holes lining up with the two holes in the backside of the UTG Accushot scope mounts. Simple and strong. 1/2" aluminum tubing welded to the L-shape with a slight upward curvature, I have Rigid Tools ratcheting tubing bender 3" radius, to get the stock up and away from the pistol grip by rising up over it. Also offset to right so I can shoot right or left eyed, prefer left but I'm right-handed left eye dominant

Bi-Pod Attachment:
Made a male picatinny accessory piece from 1/8" x 3/4" aluminum flat bar. Easy and it works well. Bolted it to the underside of the trigger guard using the existing access hole for 1st stage trigger adjustment then added another bolt forward of that going into the trigger guard where it turns upward. Lots of meat to screw into.

Regulator:
The screw that adjusts it is set to .26mm below flush. Like most of us don't really know what reg pressure is but it shoots very well. No up or down creep.

Hammer Spring:
2.5 to 3 turns in. Zero turns is when top of HS nut is flush with HS "bolt". Drilled access hole in pistol grip to actually see the hammer spring adjustment point.

Transfer Port:
2 turns in

Additional O-ring:
Too lazy to find the parts diagram but I added an o-ring between the receiver and the shiny aluminum part that is at the end of the tank. It would NOT SEAL without that o-ring. NO leaks!

Second Stage Trigger:
Added an access hole to adjust it without removing pistol grip. It's too heavy for me but I don't have any other springs to try AND MotorHead wisely advised me to be careful polishing it because of the poor tolerances between trigger guts and roll pins. I can live with it.

Getting 45 consistent POI shots on my 17 yard range in .22, chrony coming soon. Shot it at 100 yards yesterday and only saw one pellet hit the paper but I could see dust behind the paper so I kept shooting my five shot group. 1st shot wild, terrible bracing, but I got four shots into a 2-3/8" group. I think I can shoot a 1.5" group at 100 yards, later.

question DUY , did you open up the angled port from the front connection block to the valve , i think its .5 mm as stock ?? one of the other forum members drilled his out to 6mm , which too some courage i imagine.

I can't picture the hole you are talking about, wish I could. Looking for a parts diagram at the moment.

its the only hole thaat goes from the front tube to the rear valve .. If you take out the large chrome 4 bolt part at the rear of the air cylinder, you will see it in the block.. its tiny and easily goes unnoticed.

[JohnnyPDX]

OK I;m with you! Phew. That hole is miniscule!!!!!!!!

I did miss it the first time then pointed it up where it is now. .5mm to 6mm is a giant change.

Dumb question time....... what do you get by enlarging it?

Thank You for responding.

[JohnnyPDX]

parts diagram...

I believe you are talking about the tiny hole where the red arrow points to? We can't see it, obviously, but we know it's there between the o-rings.

Sorry to pester you.

[Rob M]

in the block , where tht part sits with 2 orings is where the tiny weep hole exists.. ( otherwise theres no way for air to get to the back of the gun)
when i refer to the block , im referring to reciever where the trigger, valve, and everything resides..
By opening that port to 6mm, he basiically doubled his plenum.. since that air is now readily aavailable to the valve ( assuming the valve is also opened up at the front where the spring retainer cap is

[JohnnyPDX]

Thank You. I'd better leave that alone for now. Maybe later on another PP700.

This one is performing nicely even at 100 yards.

Just curious and like to learn about this stuff.

Again, Thanks.

[JohnnyPDX]

... since that air is now readily available to the valve ( assuming the valve is also opened up at the front where the spring retainer cap is

I believe, in the BOLD and blue quote, you are saying the regulator has been defeated?

not necessarily , since its just an airpath from the reg to the valve.. its not changing any other functions.

[JohnnyPDX]

Thank You.

I have not drilled that one out yet. I do like the reg and plan to keep it regulated with oem reg and 13ci bottle. trying to get rid of the bulky paintball reg.

I think having a mill and a 6mm endmill would be an easy job once everything is set up. I will be going the other route by having a plenum mounted on the side...Dont care about the orientation so it may be an inch of plenum sticking out. or maybe I can get creative and make a square plenum mated to the side for more streamline...still running wild thoughts here.....

[Rob M]

yep, any solution will do for a prototype , also , by drilling the passage hole theres less wall for the gauge to seal .. that secondary gauge idea is a huge gain for the pp700 since everyone is basiically guessing the reg pressure on these..

[JungleShooter]

That secondary gauge idea is a huge gain for the PP700 since everyone is basically guessing the reg pressure on these.

Yes, agreed, a huge gain for the PP700.
 
Though not quite for "everyone" — since some like me have lost the Chinese regulator lottery so catastrophically that we went to the Dutch for a Huma bailout.... 😊

Very true, me too, haha!

[Rob M]

DUY , happy birthday , I made you something and just need your address.. Its a blank since i dont know what your mounting to it , it needs to be vented from top to bottom , but its threaded for direct connection to the pp700 main block with m17 threads.

basically , you need to get some orings and drill a few holes ( and tap that backside for 1/2nps ) Its some work left for sure but probably under 1 hr with a drill press .The back has 2 pockets, just so u dont have to fiddle with finding ccenter..
 I would have gone further but not sure what tank your using , or what you have planned.
send your addy if you want it , if you pass Up ill get a tank for it and use it on mine.

[Rob M]

and no , i wont be offfended if you dont want it (-'
