For anyone doing what I'm doing and wants to pick up a barrel press jig, GPW just restocked and I talked to the owner on the phone and he says they're selling fast so grab one while you can or get scalped on ebay for 3x the price.

Good news everyone, Chefur threaded barrels are back on the menu.
also picked up the SiCo facemount piston because somehow its cheaper on chefurs site vs anywhere else I could find it.
