Talking now cal .25 here.
I just blew up the pellet probe - Huma dual port oring for a first time for a while. I just checked Huma is calling it V2 (version 2 ???)
NP, I got home from my range... I want to replace it now, but the oring won't fit the groove.......
Last year I bough a large order , and based on BOM "Barrel Kit for Impact" rev date 2020.04.07 (I have that pdf on my HD).
The FX A2 oring size is 6.4x1.3 NBR70.
OK...I have two bags of these but in NBR90, it is a harder rubber harder to install, but I have a feel that this groove in Huma brass piece is shallower?
Edit:
I just found it @ Huma website, they had a change, but they don't list the new size/dimensions. That is no F bueno....
" We have modified the o-ring groove dimensions and and locating notch of the transferport to be compatible with both the newest rifles as well as the older versions from FX.
