Its all done...just waiting for the fill conector..
Its a standard 2240 apart from a .177 14" barrel
& steel breech...
the tank is a 215cc with a 850psi valve hopeing for
around 700fps with a high shot count...
Its all pretty simple..just a couple of machined stainless
fitting to hold the tank & replace the powerlet...
The tube is 3mm SS has a 1mm bore.
The tank has the same thread as a CO2 tank so its just un-srcew
one and srcew in the other to change from air to Co2...
