I think one of the biggest obstacles to airgun sports is the air. The chinese made pumps and guns have helped, but the stuff gets damned expensive quick.
A base FX air rifle is still about $1200. No scope, no mounts. Nomad compressor is $800.
$1200 for a base Air Force Texan to go big bore. $500- $600 now for a 4500psi tank now.
Driving 1+ hours to refill a tank is out for me. The more places to fill, the better.
I'm running around with an AV Avenger with a DonnyFL with a chinese pump and an ATN refurb scope. Probably $1200 in for the whole package. That's trying to enjoy the hobby on the cheap and you'll still have a hard time reaching the accuracy of FX or Daystate.
I love it because I get to shoot more on property in town without anyone else getting in my business, but damn, it's as spendy as real firearms.
