Fx wildcat mk3 problem

[Chuck-in-Ohio]

Merely installing the O ring removed from the FX reg might not work, as the joint between it and the Huma plenum being visible in the adjustment hole might lead to just blowing the O ring out through that hole.



IF that O ring seal winds up below the hole, it may very well work.

Ok so now I’ve got it working. I actually removed the wrong o ring from the reg lol

i can only guesstimate the reg pressure from the fx gauge to be at 125, whereas before it was 150

previously it was shooting 25gr at 900 with reg at 150, then 935 with the dual transfer port with same reg at 150 and now 970 with both tp and plenum with reg now 125 
Good gains in power, more than what I actually wanted or expected 

however, the fx tube gauge is still not working

change the derlin washer on the tube gauge and snug it by hand, to tight will block air to gauge. You can snug a little more after filling if it leaks.

Yup that’s the next step ... anyone know the size of that derlin washer?

Glad to hear that you got it shooting again, and good gains came from your mods!

Super support you received and happy that you have the rifle shooting again ! 
have fun with it even if your mods worked out a bit stronger than you wanted . You can always do steps back. ( original TF port )

Thanks for all the input guys 

since I can’t use the external reg pressure adjustment with the huma plenum, I’ve ordered the huma reg too

These mods coupled with the Ernest plenum should be interesting 

 

[yalel]

Interesting maybe but I believe it makes more sense for your sniper to install external 2.5” Ernest Rowe PLenum than an internal HUMA plenum that takes away from your filling capacity, takes away your external regulator adjustment and will very likely be too much of the “good” when combined with the Ernest Rowe. Just my 2 cents but I would seriously reconsider your choices as the AMP regulator is just as fine as a HUMA despite probably a slight shorter longevity but then a new AMP is cheap enough ....

cheers

Yes good points and I’ll most likely do just that in the end
