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😂
