As described
Maybe it's not the stock of my bullboss Bought these to have regulated cylinders, haven't aired them because of issues with the regulators, but both had a few PSI when they arrived

Leaks
After it the pressure wouldn’t go up at all, i noticed it is leaking from the output port. Weird. Hopefully the replacement works.

Inconsistent
First tank showed up and was "overfilled" 50 bar I thought. But actually when the tank was empty it showed it had 50 bar in it. Returned that... Second tank was second completely empty of air. Every one knows you don't leave these tanks empty... It seams to be holding air for now though after pumped up...

Tube arrived well packed. Like with all my pcp stuff was stripped cleaned ,few sharp threads removed. Added de pinger lubed again with silicon grease reinstalled filled and perfect. Would have worked straight out the box just fine . No longer brass valve unit but steel. Tube seems to be strayed black not blued like old ones were but is durable. Gauge is accurate. Really impressed with extra cc and quality. Using this on the standard UK barrel length which is slightly shorter the long. 3.50" shorter than tube.made a 20 mm external dia mod to suit . Excellent results. In all a excellent upgrade ,extra cc good price. Result thank you. UK buyer
