PP700 adventure started(Artemis PP700s-a)

[SoCalZac]

Ok thanks guys. I ported the valve to 5/32 put everything back together and now it is just dumping air out of the barrel. I don’t know what I did wrong but somethings not right. Anyone have any idea of what is going on.

 I did accidentally dry fire the gun with no air in it when I was taking everything apart could that have screwed up the poppet?

Edit:
I tried increasing the valve spring tension and firing it with my tank attached to try to get it to seal and still no go. The poppet looks good with no nicks or anything wrong with it. I’m starting to get frustrated with it. I don’t understand what happened!

[SoCalZac]

Man I feel like a dummy. It ended up not being the poppet but the oring around the gauge. I must not of tightened it after degassing and when I filled the gun it blew the oring out the side. It’s all back together now and leak free.

It is a lot louder now that the power is up on it.  It still not to bad. I will adjust the regulator next week when I get back from vaca. Glad I got figured out before going it would of drove me mad all week. 😜😜

Happy to hear it's an easy fix.

There's a few vendors selling adaptors and silencers for this pop-pistol.  I have a Rocker1 LDC/adapter (in fact, my pistol was his guinea pig) and they bring the noise to a very backyard-friendly level.

Me Too. I have the Rocker1 adapter and ldc on my for night scorpion hunting. It is quiet and kill'n the heck out out them! Muahahahaha!!!


For grins, I have a DonnyFl Shogun here and put it on. It's Long---!


Thought It failed to fire. Nope, that quiet. But it is heavy and long. It would be a natural for a carbine build with this little gun though. 


Scorpions killed this season so far----1,575

Michael you need to get the NOE-217-20-RF, shooting that much would save you money in the long run, it wouldn't take long for that mold to pay for itself.

[KnifeMaker]

Wayne, I have two molds here on loan. One from Don, the 27 noe pellet mold. it loves them!


The other, a decked mold I did for Denis that I size down to .216 for it. Both are dead accurate! Other than when the pp77 firs arrived and I tried cpl's in it, it hasn't eaten store bought pellets in  while.

It's on the to do list.

read the whole thread twice, great info, got mine PP700s-a yesterday, did some mods to it, put a grubscrew on side where barrel seems to want to rotatate, tighten the breach as there where some minor air blowing, now its better almost competely gone, did some tuning with regulator pressure and hammerspring-tension, all good except ONE thing  , it seems after I did turn the regulator just a bit, now it seems it leaking  .....  Didnt leak before, put like 50 shoots trew it so far.... All I did that could cause a leak was: drained the tube from air and filled it once, and turned the regulator CW like half a turn to get the reg pressure at around 95 bar, so where could it leak now???

its like 5 bar leak in 2 hours..

[rumbleUU]

did triggerwork now... removed all parts. polished, small amount MoS2 grease, the trigger i like 5 times better now  ..... put some loctite to prevent grubsrews moving....

Now I need to find out if it leaks or not, could have been the full fill before, making tub a bit warm, then after an hour it got back a few bars?,,,,,,,  I did put threw som shoots one and a half hour ago before I did the trigger, I did memorized the meter was at 145 bar, now its still exactly at 145bars, crossing my fingers it will hold up..

Now I need to rest, my back hurts after all work 

Will try to shoot this little pistol another day , its great so far...

Also, my regulator seems to work, I did try like 25 shots in a row, max spread was like 5m/s over the hole series... I think thats ok, the gun is new also, so I need to get at least 500 shots trew it anyway to break in..

[Techie]

Thanks for taking the time to take pictures and show us exactly what you did.  I appreciate it.

[Rallyshark]

Nice job on the trigger work!  The real test for your regulator will be how it shoots after the gun has been sitting for a while.  The regs tend to creep, so velocity during testing and velocity after the gun hasn't been used for a while will vary wildly in some cases.

[rumbleUU]

some quick groups, the trigger is way better then stock, but still needs to be shortened in the 2:nd stage, its not a FX trigger for sure , and the stock behind is kind of wobbly, so it was hard to shoot like a stable rifle, tested quick with sniper magnum and got groups like 2-3mm CTC @ 10 Yards, then moved over to Jsb exact and the gropus seemed a bit better, but it was mostly the trigger in combination with a wobbly stock that tock me off ....

So I decided to go rest for 5 minutes, wacth a movieclip, made some improvement to the stock to get it a bit better, then I got back, made this little pistol rest as good as posible in my bags, deep breath, 3 shoots @10 Yards JSB Jumbo exact 5.52mm,,,, the picture speaks for it self  , probably the best I can shoot for a while , haha.. this is really hole in hole in hole,,THIS is FX accuracy  ,,,,   I need to take this in , will probably never happen again 

Im happy, zerod the sight, now it hits bullseye with both JSB Jumbo and H&N Sniper....  Great pistol, Just need to improve the stability of the stock in vertival led, will post some pictures later how I do that...

[rumbleUU]

By the way: How is accuracy defined? I mean if the trigger and a wobbly stock makes it hard to shot with, for me that not to blaime the accuracy, the accuracy can be good within the gun, how the internals work and the barrel it self, but not the trigger and stock..... How do you think of this matter?

[rumbleUU]

OK, the standard stock that we can buy is not that good, It can be better with some tape in som places to make it more rigid and stable, but still its to small at least for me..... So I will try to get the other stock below , this is a more rigid one, Now I have to make up how to attach it?

there has to be some part between this stock and pistol to make it look nice and be stable, I will look into what I have laying around and see if I can make something custom that will work 

[Thane]

Many, self included, have used the main grip screw mounting stock from below for a very secure mount to pistols metal.

[nervoustrigger]

After shimming mine as shown in the following photos, there is zero play and it shoulders rock solid, just as if it were a 1-piece stock.







My only other frame of reference is a telescoping AR stock fitted to a Crosman 2240 HPA:


The SPA feels much more solid when shouldered.

My main concern was the way it attaches to the flimsy plastic hand grip so I made a couple of doubler plates from scrap aluminum to spread out the load:

[rumbleUU]

nervoustrigger: I did the shimming part also, but still feels a little weak somehow?
I will use the sstandard stock to my other PP700 in 4.5mm that Ive allready order 

Anyway: Im allready halfway threw making my other stock fit with a costum attachment..... 
I did drill 2 more hole into the plates that comes with the stock pistol grip, and threaded them. This will act as a base to attach some sort of fork that I can screw into the new stock, kind of hadr explaining, better post pictures here......

I wunder if 2.5mm thick carbonfiber plates wild hold up? hmmm, But I still think aluminum is the way to go.
I had to dremel out som platsic to where the hammer goes back when cocking it...

Yes, and Im sure mine also possible have some creep, have to check that one later, Im sure the first shot is a little bit faster If I remember right..

Yepp Ive seen that, my aproach this time has to be where the plates are...
