Please, be kind to yourself. Buy a cheap compressor with all the money you saved on rifle. 
I’m guessing, from personal experience, you’ll be buying more PCPs now that you’re started down the rabbit hole.

I’m surprised that much variance in pressure readings, I haven’t ran into that issue yet. I guess to be on the safe side, go with the higher pressure reading.Upvote 0
well I disconnected pump just in case it some how allowed a leak down while I was taking a break. somewhere under 2000 they came closer together. It took 140 pumps from 0 to 2000. And another 50 pumps from 2000 to 3000 whew was starting to sweat on the 2nd 100 pumps.
So going forward assuming I draw down to 2000 it would take like 50 pumps.
I do feel like my grandpa bod is slightly more pumped up.

Initial thoughts.
1. This is every bit as loud as unsilenced .22 lr (standard velocity). I don't understand why it has this loud of a report.
2. Had a couple of times that I loaded and did not get a full cock/engagment so had to pull mag out to recock. That's a learning thing.
3. Mounted Japan 2-7X32 and front green fiber is way up in sight view almost at cross hair.
4. The good walked the scope sighting in and hit the target at 15 yards off monopod easy peasy.
5. Of course no recoil.

Instead of rc car bearing i had rc car bushing, they normally get upgraded to bearings in wheels.

Back off hammer spring. Sounds like adj is near max, should help cocking and loudness. 4-5 turns counter clockwise.

I assume that is the allen head on top breach end toward stock. I moved it 4 X 1/4 turns counter clockwise.
Well 4 X 1/4 turns didn't change much. You probably meant what you said 4 turns. Thank you for this advice.
I just shot from upstairs window. Wow on target but dang the reverberating echo.
I may have to go get the silencer off my .22 lr. Well so much for that idea the threads must be slightly different than what's on my .22lr it turned maybe half a turn and then it stopped.

I could download the STL files one by one.
Am I seeing right, that the endcap has holes to allow the air to vent?

25 ish shots and 50 pumps later catch my breath. The 25 shots go fast. But the pumping will be an ammo saver in the long run.
3 turns of spring cocking still an issue and 4 turns not enough air. 3.5 turns and well it's a little less bark and seems to still have the same impact.
It was respectable with Crossman hollow point 14.3 grain, but It really likes JSB match diabolo exact jumbo express 14.35 gr
And 30 more shots and well it's time to pump again. Darn it 30 shots takes 60 pumps. So it's about 2 pumps per shot.
On the good side I was getting tennis elbow from the springer cocking so now I'm just getting ripped core muscles (ok more like bruises on my stomach).
Getting tired may have to shoot some .22lr
Does anyone make an aluminum moderator. Interesting that I can't find any such device at large air gun online stores.

I put Buck-Rail 3D printed ones on mine - makes a huge difference in report. I went with the larger, non-tapered model because Chris at Buck-Rail said it is a littler quieter than tapered model. Be aware that you won’t be able to take fill cap on and off with larger suppressor mounted. Not a big deal to me - I either take suppressor off and replace cap, or just leave cap off. Buck-Rail also sells aluminum suppressors - quite a bit more expensive though.

Ah! Thank you, I realized after I posted that asking if you had ground bearing down was a stupid question - that would be nigh impossible. My mouth outruns my brain pretty frequently.

here it is fully assembled next to a sumo, took a vice to get the thread caps on so I'll never be able to open it back up. wrapped baffles with some 0000 steel wool cuz why not.
P.S. it took 7 baffles not 6 ?

Crossman premier domed (older box maybe 5 years old) 14.3 grain has same impact point as JSB 14.35 and seemed to like them about as much. I'll need a warmer, less windy day, and good arm strength to test these on paper. both are better th cphp.
here are some pics

When my ICON showed up it was maxed out for power. With 10.6grn pellets it wasa shooting 1040's and crazy loud. I tuned the adjuster WAY down and settled at 750, much better on the noise level and 70+ shots on a fill. I still added a Buck Rail moderator for a whisper quiet experience.

Yes, but not fully lined up as it was taken from another moderator. You could drill them out if you wanted.

I'm going to have to take a break I've developed a blister on my hand not from the pumping but the cocking.
Probably a good thing I was feeling good about myself until I saw the splats on paper.
I will say around shot 25 it started to shot higher. Odd I thought. So I read this regarding hammer spring adjustment. Ahh!!!

FYI the sale is over suddenly I feel lucky again.
