FX 700 cc bottle on wildcat mk3 bt?

I will ad. I have the vp model as well and I bought I believe a tuxing 420 cc carbon bottle. It worked fine but note on the end of you aluminum bottle there is a spacer on there with the fx valve. I had to use that spacer with the tuxing bottle to push it forward just enough for the stock to clear the front of the bottle. The first attempt I didn’t use the spacer and the bottle hit the front of the stock once it was screwed in about 3/4 of the way.
 
Thank you all, doin some measurin, you are all correct. (I have a 580 on it now). Having it tuned to 1,000 (plus minus) brings shot count down obviously so…. but I am going to go with a moderator that will clear it and buy some more mags. Maybe gonna make it way front end heavy but wemshall see. Love the gun! And since I have forgotten to stop shootin at lo press (and boogered up my dreamline) I run it with the number of mags it will shoot. So im oitta pellets I am outta air. KISS! I have operated gun systems all my 80 year life (miniguns, m60, rockets and myriad shotguns) so remembering to chk air press seems too hard😀. Many thanks y’all! p.s. Im really only 79😂
 
You will be very limited in what moderators you can run. Only one equal to or less than in diameter of the shroud will fit. In essence the bottle will fit but I’m guessing it will be longer than the barrel.
You got a skinny mod you like or recommend. And can they be as suppressive as a “fatter” one would you think?
