Not sure why FX included an MK2 Owner's manual with my MK3 Wildcat but photos of how to adjust regulator, after removing stock, seems identical to mine. Members who've posted mention a non-externally adjustable regulator also in the mix, which suggests removing air tube to adjust. It appears three regulator styles are involved, not counting the latest twin-regulated Wildcat/Maverick hybrid. Haven't visited HUMA website in a while, pretty sure they're clear about which style is appropriate and any caliber specific issues. WMSo, stupid question: the late Mk2 reg and the early mk3 reg are the same design, correct? Also are the regs the same across calibers. I ask because I need one for my MK2 and I thought I would get a huma for my MK3. Huma offers a lower psi and a 'tuning reg' for your and my guns.
