Hi airgunners, i was recently gifted a wildcat mk3 by a good friend of mine. However im finding that i get what i consider too few shots (1 and a half magazines) and wanted to know if it was possible to switch the cilinder for one from a maverick and turn it into a wildcat bt, ive looked at the exploded view and the parts (cylinder, plenum and dropblock) seem to all fit, but any of yall know?

Possible yes, but quite expensive. Finding all the right parts might be tricky too since we no longer have FX USA to order from. Utah Air is supposed to be the new US rep for FX but Im not sure how many spare parts they have on hand yet. Honestly it would be better to sell the tube version and buy a used bottle version here in the classifieds. Although I get wanting to keep and improve the one your friend gave you too.

It can be done in several ways. Buying parts 12, 14, and 16 will get you there. Stacking various plenums will get you there, but depending on the parts you use, you may or may not be able to utilize your second regulator. I took the hard way with my conversion and cut the air tube down and cut female threads in it. I then made a male x male adapter to mate the bottle adapter to the shortened air tube. Regardless of how to manage the above portion of your project, the stock will have to undergo some mods up front to accommodate the drop of the bottle adapter and also allow for the front gauges and foster fill fitting. It’s involved, but rewarding when you pull it off. My gun is a MK1 and I’m using a 170cc FX screw on air cylinder rather than a fiber wrapped bottle (needed the smaller diameter to clear a huge moderator) but the process is the same.

What caliber is it? I have a compact .22 (tube version) and get 3 mags. I would say your tune is wasting air.

Its a .22 cal, yeah thats a lot of mags, the way my friend had it it was shooting h&n barracuda 21 gr pellets at 915 fps and the power wheel is on 1 with adj screw at min.the reg was changed to a Huma one and set to 130 bar. I tried to lower it but could not for the life of me unscrew the valve side of the cylinder

I would turn the reg down and the power wheel up. Im shooting .22 hades at 930 my reg is at 100 and my power wheel is on 4. If you want to shoot the 21 grn pellets you may need do a little finagling the power wheel or the reg or both a little but you should be able to get better air efficiency then what you have now.

Is it a wildcat mk3 (I think you said it is in the original post)? If so the reg should be on the outside of the tube. I have to take the stock off to get to it, but you shouldn’t have to remove the air tube.
