I have an FX Crown I purchased new in May 2018, SN FXC 181098. I am interested in doing some upgrades for increasing power for shooting slugs.
I've looked at several components for doing this, such as Huma Regulator, hammer weights, Huma pellet probe and hammer springs. It seems inorder to order some replacements, I need to know what generation or MK model my Crown is, which I do not know. Right now I am getting about 850 fps with NSA 33.5 grain 25 cal slugs at 145 bar hammer max. Would like to be able to get 900+ fps. I have installed a superior liner and also a Huma dual transfer port, which didn't change velocity at all. Help requested.
