Natchez had these going out the door for $12.95 in .22 and .177. Yes, you read that right and with scope, pellets and a hat. I bought one and my wife found shipping for $15 but I needed some CCI A17 ammo so a case of that got me free shipping. Has anyone converted one of these to run on a tether or bottle or something other than expensive prefilled N2 cartridges? If nothing else I got some pellets and a scope and my neighbor gets a new hat as I do not wear ball caps.
