Tuning .177 for Hunter FT or just a nice hunter

This was a fun build. Learned even more about the Kuzey after this one. Required a mod to the plenum of the Huma to seal. Moved the o'ring from the inside to the outside At the valve seal due to the slight difference from the Kral valve. Kuzey uses more of an AirArms design than the Evanix design of Kral. Added a front gauge to get both a tube pressure and reg pressure reading. Uses a double shroud for stiffness. Donnyfl suppressor adapter and all new internals plus a lighter hammer with debounce hammer spring. Polished the trigger and it really breaks clean. I really wish it had turned out this way for the original buyer but didn't know the plenum o'ring wasn't going to seal properly so I just refunded him and got it back to finish. Turned out better than I expected in the end. 10.34 JSB average 890's with about a 15fps spread over the full string. That's with the external hammerspring adjuster on the lowest setting and 100bar on the reg. It's even tighter ES in my testing when I sorted them by weight. Rifle is listed in the classifieds if you're looking for an HFT gun.
