I just splurged on a sweet new scope setup for the X20S. Tonight I'm going to break her on down and hone the compression chamber. That is really the only thing I haven't done, and it's something I've been kind of afraid to do. I am also going to weight the piston a little bit. I'm waiting untill I arrive at my new hone in Texas to send my chrony in for a fix, so by then she should be broke in AGAIN for the 3rd frikken time. If I do everything right, I believe that the gun is capable of 17 fpe and change. When i get the chrony fixed I'll experiment with weight in the piston untill I hit the sweet spot with the Kodiaks. The gun is a sweet shooter already, but I just can't leave well enough alone!!

Bryan, What kind of scope did you get? Looking forward to your 17fpe mods (are you adding washers to the tophat?) and details.
Thanks
John

Probably just going to use pennies stacked on top of it. Older, copper pennies. They fit perfectly. I found that out when i broke the spring on my first X10. I just threw away the broken piece, and spaced it up with pennies untill i had about 1/4" of preload ( just enough to hold the spring/tophat together lol). Worked like a charm, didn't even notice a loss in power! But the spring broke again after that, in 2 more places, before the Maccari E3650 I ordered for her arrived. Eventually I sold it, but i miss it. With the E3650 and apex seal, that was a real, sweet shooting little gun. Zero hold sensitivity and stacked cphp's and cpum's all day long. These days it belongs to Dick Tracey.
EDIT- Almost forgot! I picked up a new CenterPoint 4-16x40 Adventure class today at Wal-Mart. I had one in the past, and I liked it too, but eventually traded it to a fellow GTA member. His WFH destroyed that scope though=( Popped the turret adjustment knob right out of place! But these days they are built differently, with one-piece aluminum tube and some other changes. I think it's improved overall- especially the turret adjustments. They actually have covers now, instead of the lock-down design. I also picked up a CenterPoint laser/flashlight combo with pressure switches at Dick's today, and they are already mated-up to that scope. I have some BKL dovetail-to-weaver adapters coming from Pyramyd with another shipment of Kodiaks as well, so that I can take advantage of those weaver mounts that come with the scope. Pretty sweet little set-up.

I'll have to try the penny stackup. I have a couple of the CenterPoints 4-16x40 AOs from Wally's, they work well, my only complaint is that it is really difficult to rotate the knob to change the reticle color.
thanks
John.

I stuck them together with tar last time. This time around it'll just be some moly, if i can ever get the dang gun apart. Instead of making another spring compressor, I just used a irwin quick-grip bar clamp. That tarantula almost proved too much for it during installation, and right now I'm having a really hard time trying to get it out. Of course, i know a technique to remove it by hand but it's risky- although I've done it before i might just have to leave the spring in the gun as it is. It's driving me nuts though!
EDIT- I've decided to err on the side of caution. I rekon that sixteen and a half foot-pounds is enough with the venerable Kodiak pellet and it's superior BC, and besides that, the end cap is becoming more and more worn as I try to use this bar clamp. It reached the point that it wouldn't take up slack during installation, and right now I can't get enough pressure to get the pin out of the end of the compression tube. The internals of this girl are gonna stay as is until either I get a stronger bar clamp, or the spring breaks! Might still be getting better power than last time I chronied it anyway- But I won't know untill I get the chrony fixed. I'm having trouble with my I-touch, but i got some pics of the washers and breech block on my phone so I'll try to post them later.
AND EDIT AGAIN- Well, I just couldn't stand it! I'll not let this thing beat me! I got her opened up. Apparently a drop of locktite was on the pin from the bolt that holds in the trigger group, making the pin harder to tap out. The spring isn't so bad anymore, because all that excessive pre-load is gone now that it's set. The tune continues! Taking pics this time around.

Good luck. I thought the plastic end-cap would break apart if I put too much pressure on it, so I just bypass it.
The Tarantula spring I have measures 12.5" (unset) compared to the stock spring (measured 9.92" set). I have not installed it yet, but I did modify (added some L brackets for support) my spring compressor for this future mod, photos below.

Looks like you've got a nice workshop there. The plastic end cap handles the pressure fine, btw. My problem was the locktite that had dripped on the retainer pin, and I kept cranking down on that bar clamp trying to get it loose. I figured it out though, and tapped it out. Now that it's set it's got maybe a inch or two of preload but during initial installation, oh brother! I had a hard time doing that with a cheap bar clamp, let me tell you!

The suppressor seemd to be around 14 fpe. Mine was at 16.3-16.4 last time chronied, after i tuned it. Now I'm working on her some more. There's no reason why you can't get 17 fpe out of the gun without doing anything too crazy, but it could come at a cost

@ Bryan, thanks, the workshop is a mess, I can never find anything and after a clean up, it gets cluttered in no time.
@Gary T., my X20s is still breaking in, so my fpe is fairly low (~13 fpe). This was my first springer tune and I don't think the seal is broken in yet (a lot tighter fit than the original seal). I think there are a few people here that can tune them, you can probably post a request and I others can comment.

Never too late to re-size that seal. But it bet the shot cycle with that tight seal is very nice...

I like this gun also, very easy to handle and my brother-in-law wants to borrow it, could be gone for awhile.
I do think the shot cycle is nicer now, but I still wonder if I can get some of the fps back. I've never resized a seal. I have a 2nd JM seal that is 0.996" (the 1st JM seal installed was 0.992") that I could use if I screw this one up.
