Can you add a Power Plenum to the Wildcat MK3 Compact?

[LSS152]

Does anyone know if you can add a power plenum to the MK3? I think the issue would be that the Donny FL moderator would no longer fit. Is there such thing as an extension so that the moderator would work after you added the PP? It may be just easier to add a 600mm barrel instead. Anybody have any experience with this?

Yes and no? 
I had a wildcat MK2 compact 30cal and wanted to add the power plenum but the changed the wildcat where the power plenum goes on the 1st batch was called the older mk2s the made a change and now you can't add one but Ernest Rowe is making one soon that will fit. Keep checking 910 airguns website he will have it on there when done. As for the fit with a moderator you can use a koi Donny fl and it will clear.

I try do it today.

looks like there is 2 versions from MK3.

some video there was separate ring bottom of reg. This one its solid. So any plenum dont fit it.

Plan was use dual dreamline plenums. And dual reg with huma.

so installed plenums to front just add some tube volume. This is with 700mm barrel. Have to machine it down later.

How much you have clerance to barrel end from tube?

So the original batch MKIII's were using the airtube/cap assembly like on the MKII's so the existing power plenum from 910 worked great. Then FX changed the (not much) later MKIII's to a new endcap/plenum style so that rendered the 910 power plenum obsolete for the newer revision MKIII's. 910 is supposed to have something in the works as that required a redesign. If you have a Compact WC you will need to use a smaller diameter moderator as mentioned above or the extended length of the airtube may hit your moderator, or you can also use a Huggett shroud that also has a built in moderator. That's what I chose to do so my overall length on my Compact is now almost 1/2" in shorter than with the original setup using the DonnieFL moderator. Watch the 910 Airgun Tuning web site and they will have the new ones there at some point.

Thank you so much for explaining this to me. I tried to do a search but most of the topics I found confused me even more. Thanks again!
