All gone for now, but I am capable of machining more in the future now that I have CNC capabilities should there be enough demand.
They are contoured to fit the tubes of a PGP, and will fit many other tube based brass guns as well. They are threaded for 5/16"-24, which is the standard thread you will find on Autococker rams. Threaded all the way through to allow you to mount on either side of the gun.
$15 shipped for one, $27 shipped for two.
If you need more than two, let me know and we can work something out. I can always make more if there is demand.
