Get a good pair of snap ring pliers to remove the original muzzle bushing. David's fine gear threads onto the barrel hand tight. Haven't had issues with it coming loose afterwards.

That's what I used was a pair of snap ring pliers on mine as well!

[Rallyshark]

I used a small pair of needle nose pliers myself, but anything remotely similar should work just fine. 

[AGEnthused]

Thanks for the quick replies, I will be buying a pair of snap ring pliers next, it certainly looks like a tool worth having.

[Masochisti]

That's about the power level I'm getting, but my ES widens a bit if I go much more than 30 shots... what's your ES like? They are sweet, aren't they?

Heres the full string:


First shot is always bit low for some reason. ES is not the best but I can live with it. If I give the hammer spring a 1/4 turn CW it will give me 660fps but only 28-30 shots in that power.

[Cathartes]

Not bad at all. 4.6% for the first 30, which is certainly hunting worthy, and 6.8% if extended to 40, which should be still be fine in pistol ranges. Nice tune, one of the best I've seen, especially with that many shots!

Mine is scheduled for delivery tomorrow (8/7)...You guys are a bad influence...

I sure wish Photobucket had not crapped on all of the pictures...

  I think I finally have mine sorted out now I just need more trigger time. I had a clipping problem with with the pellet clipping as it was exiting the LDC fixed that issue  and have the barrel indexed so when I take it apart I go back together exactly the same the other thing I did was set the Red dot 1/2 on the breech and 1/2 over the barrel shroud which stabilizes the barrel nicely. now my groups are consistent and I am getting ~ quarter sized groups at ten yards.

Did I mention that this little piston is fun to shoot and accurate

Hey guys, I wanted to ask about a leak that cropped up after removing and reinstalling the regulator.
 
Hopefully I simply nicked one of the O-rings...either the small one on the slender inlet part that the air tube threads onto, or one of the larger ones on the exhaust side that fit into the receiver.  Everything was greased well and seemed to go together without a hitch, and normally it's obvious to me when there's a hangup but I can't rule it out until I disassemble it tonight.
 
The reason I wanted to go ahead and ask is because in hindsight it's not obvious to me how the slender inlet stem seals where it threads to the regulator body.  I'm talking about the part that is removed with a spanner wrench / snap ring pliers.  Does it seal by crushing against the white flat washer?  If so, I suspect that's where my leak is.  The plastic seemed pretty hard like acetal and getting two hard flat surfaces to seal isn't easy.

Looking for a little help with tuning my PP700. I have already ran 300 pellets through it so far. I have not adjusted the regulator only the hammer. Transfer port screw is showing 1 thread exposed.  I am looking to be around 670fps with 15.89 jsb or AA 16g.  Been using AA 16g for the break in. 

Here is a string. I dry fired 3 times before starting the string on a 210 bar fill and shot down to 100bar.

661     680    691
669     677    684
670     686    672
675     686    668
678     689    650
671     689    645
677     695    634
675     700
674     699
668     692

Any suggestion's will be greatly appreciated.   Thanks in advance!

Brandon, what happens to the velocity if you wait a couple of minutes between shots, especially early in the shot string?  It seems this regulator creep is a real problem with this pistol.  It's driving me crazy.  I'm trying every adjustment I can think of, and I still get a 100+ fps drop in velocity if I wait a couple minutes between shots.  I noticed this variance goes away once the pressure is down to mid-range, but the first half of the shot string shows it big time.

Also, breech seal leakage seems to be very common with this pistol, although it does not seem to be hurting anything except maybe wasting some air.  Wrap some tissue paper around the breech and watch it get blown away when you shoot.

I'm getting more and more disappointed in this pistol.  I have about 400 shots through it and still the regulator creep exists.

[Plinker4life]

Yeah the breech leaks air.  I am just wondering if it will tune flatter at lower powers? I have not tried waiting that long between shots. Pistol was slinging them around 705 for 15 shots when the pistol arrived.

[MonsterMaxx]

My reg is very creepy too.  ES of 50/60. FPS was very much dependant on how long it sat.  And the whole gun is leaking in general.  I've tested it several times charging it and letting it sit overnight, it leaks way down.  David asked for it back last week, but I wanted to show it off at a cookout this weekend so it's just getting sent out today.

I guess it'll get super special luv now.  I'm really sorry he's having to put all this effort into what ought to be nice out of the box and just get a little extra.  It is a cheap made in china item.  Not like it's a $2k FX or anything.  You get what you pay for.

I like it, am not unhappy at all, just thinking it could be better and I'm confident it will be when I get it back.  Just going to take some work.

I think when it does get back, I'm going to mount a rifle scope to it and see what it'll really do at 30 yds.  Things kinda fell apart beyond the 13 where it was punching a nice big hole.  But question at 30 is what the red dot has at a distance where the dot is really covering the bull entirely and we are relying on 50yr old eyes to see that far.

Hey guys, I wanted to ask about a leak that cropped up after removing and reinstalling the regulator.

Jason, you are correct in that the white acetal seat is the seal when properly tightened with a spanner wrench.
To get mine to be leak tight I had to add a O-Ring as suggested on the Facebook forum.

What he said^^^ !  I had to do the same thing.  Also be careful not to flip that white washer around the wrong way, or it won't let any air out.  You'll have to VERY CAREFULLY unscrew the cylinder until it leaks to get the air out.  I also had air leak at the little fill "valve".  I had to take the end off of the air tube, and unscrew the little flathead screw in there, and replace that small o-ring.  There were small metal shavings on it.  I've heard some people just clean it, and it fixes the leak where the fill probe goes. 

Yeah the breech leaks air.  I am just wondering if it will tune flatter at lower powers? I have not tried waiting that long between shots. Pistol was slinging them around 705 for 15 shots when the pistol arrived.

It has been my experience that it does better with the "regulator" cranked down for a rather high setting for my gun.  In other words, it does better at higher power.  I use mine for pesting more than anything.  Given some of the creep issues, I usually leave it at 160-170 bar.  That way it is always on point when I need it at the back door.  I haven't really had creep issues myself, but I'd rather leave it at lower pressures, just in case.  I like to do things with one shot  

[Cathartes]

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.

As far as the breech leak goes, I had this too, and I read on the Facebook group to screw the valve body in more. You have to have the pressure lowered, but it didn't really take much tightening to stop the leak. I used two leftover allen wrenches in a vise in place of a spanner wrench.

I also had to reseal mine to fix a leak around the gauge. I gave the o-rings an upgrade.

On the whole, I've probably spent at least 8 solid hours tuning, fiddling with, and resealing this gun. I feel that it's totally worth it, though. I reach for this gun more than I do any other. So fun to shoot.

Even with my hammer cranked all the way I can still go overboard with the regulator.  I backed the reg out and I've been good to go since.  This little pistol is an awesome hunter.

One of the first things my brother said when he shot it was "This thing kicks", he really got a charge out of this gun.

A lot of guys with Impacts wish that were a true statement...

[nervoustrigger]

Hi Bob, thanks for the info on the reg leak.  I guess that explains why the inlet piece was tightened like grim death!  It's funny, on the way home from work yesterday I was thinking, "Hmm, I wonder if I can just drop an O-ring into it."
 
Thanks again, I'll fix that right up this evening.

[Sfttailrdr46]

  I spent a couple hours last night playing / testing different pellets and JSB, Air Arms and H&N pellets all group well the Benji's not so good maybe too hard of a skirt on the pellets. I am really liking this inexpensive  little PCP pistol . I will chrony a few shots later this week to see what kind of velocity I am getting with the different pellets it shoots well. So far the JSB 18.13 seem to be the most accurate and at ten yards there is enough power to punch through a piece of 5/8" furniture grade plywood.

I gotta hope it's true, I just ordered an Impact.  The streamline is flawless, does exactly what they advertised.
