When it comes to Hubens Kelly is the man. Customer service is unbeatable, not needed for the guns themselves but for advice. Kelly's very ease to deal with, no high pressure, very laid back. I've three of them now a .25, .22 and a .22 moded to .177. I asked him if could mod a .25 to .30, not enough meat in the magazine to accommodate the .30 ammo. I haven't persued it. I haven't given up on the idea, I'll come back to the mod at a latter date.
