You will be far better off at Krazy Kool should something go wrong with the gun. I have a gun at NEA going on 3 months for a simple pellet probe replacement, and can't seem to get them to get the part and work on it.
I bought both my Huben K1 and my Huben GK1 , .25 cal from him. He is the only Huben dealer I will do business with. He can repair Hubens in a timely fashion, has parts and no BS like some of these guys.
