Thanks, WMā¦ā¦I always clean (and polish) my barrels first thing. I wonāt need the moderator as Iām shooting in a mountain location. And I might just leave the probe in the gun.Moderator is M14x1.25 thread, Talon Tunes has AGT brand, or find adapter. Fill probe is smaller than original Uragan (and possibly Vulcan), will need adapter. Haven't seen any aftermarket one-piece fill probes for U2, yet. Good barrel cleaning is recommended, mine was dirty. Ballistol and PatchWorm did the trick. WM
