    EDOSAN, yeah my brotha… that was awesome! +1 for sure. I already have the 580cc bottle and didn't realize it was so much bigger. It really doesn't look like it until sitting next to the smaller one. How many of these parts are you making vs. buying? I remember saying you were either machining down or making some parts. I need to pick your brain a little more. So have you shot it since installing the parts? What kind of gains are you seeing? 

    Thanks buddy, Stoti

    Hello Stoti! thanks! ;)

    Externals are bought, internals are made or given (by ER).A Lathe machine is coming this way, new challenge is to learn, but I have Ernest giving me some help in that area + a local lathe worker so pretty sure I will learn fast! :D by the end of this month it should be up and running.
    I am making a larger plenum valvetube that fits the old valveHousing, hammer weights and larger valveseats but is a slow process without a lathe (I depend on my "lathe friend" time)

    The work you saw I did it last night so no time to shoot, but I have experience and I know the result will be good. Like I prior mention those mods will give me a total of 100 to 150 fps extra (including the elongated ports) will see, I will post the results as soon as I test this gem. ;)

    Thanks! New Impact X owner here. Received it one day after the xMKII became available. Doh! (Just my luck). Have been told there will be upgrade kits made available to go from “X” to MKII at some point which I understand would be required were I eventually to want to try the supposed .35 barrel.

     

    this is my first PCP and i’m definitely still learning! Where you talk about differences between “Mk I” and the MKII, is that from the Impact X to MKII, or is that from the original Impact that did not have the STX barrel? Or…..? If it’s the former, it sounds like “upgrading” (whenever I could get a kit) would be quite a job unless the X version already had/has some of those upgraded parts.

     

    Lastly, where do you buy things like those “Delin” o-rings?

     

    thanks again for your post and the effort it took!

    @ArmedLeftist thanks!

    Yes Impact X gen2 vs MKII, there are more differences with older impacts

    Easiest way es ebay, amazon or something like that: https://www.ebay.com/itm/Paintball-PCP-High-Pressure-PE-M10-O-Ring-Gasket-Air-Seal-Sealing-for-Mini-Gauge/123735522725?hash=item1ccf363da5:g:~cgAAOSwPb1cs7Fp (for example) is a bit thick, but it works if you do not use a hammer weight with pretention, if you do, thinner is better (2mm or 1.5mm) since the preload take extra mm and if you exceed the limitation the rod end will not seal the valve (the small oring).

    @ninelives I am! jaja it shoots pretty good, and now even better for heavy slugs

    The valve housing was made 2mm larger to make boring the larger plenum portion of the tube a single step. Less time machining means a cheaper part.

    Quick test 145 bar 0.22 26gn 970 fps 😉

    Too cold and getting darker sooner to keep shooting… Will continued…

    Good morning all

    Last night I took my MKII apart add a few improvements and rebuild, here are some pictures and findings

    Before surgery ;)

     

    Thanks for taking the time to post all this.  You've really been doing great work on the FX updates!

    Cheers,

    Rusty (might consider the 9mm when they get released)

    Yes as I tried to explain weeks ago!

    I remember (If I recall correctly we were talking about building one), but is that a fact? Or a probability? (Make sense anyway)

    So not really much difference between a MKii or a relative new X ?

    Hammer and such are all the same. I found it already a bit weird that both MKII or X have the same power levels on FX Airgun's website. Same velocity, same foot pounds/joules.

    I will wait for the .35 caliber, perhaps those are different.
