I (stupidly) bought this (before taking measurements) to be used on an Airforce Condor with a Huben Power regulator and the length of pull was way too long for me so I promptly removed it, let it set in my closet for a while, and now it is for sale. It's a nice looking tank, same one I used on my Panthera Hunter Compact front bottle setup. Since it has M18 threads it is a direct replacement/upgrade to many airguns out there.
Save a few bucks on a 500cc 300 bar tank - I'll sell for $100 shipped to your door. Includes o-ring and thread protector. Pics below:
