Cloned 230cc Air Cylinder

Hey guys hope I’m on the right subject. I shoot a BullBoss 230cc air cylinder from what I understand is it will fit a couple of Hatsan’s. When I went to order 1 a couple of weeks ago I couldn’t find one! Just couldn’t find one they were all out of stock. So found one on e-bay for about $30 more than usual ok I said I want an extra, ordered it, then received it and it was a little different at first glance. Didn’t have the Hatsan brass air port it was black, then I noticed the pin were the hammer strikes is different on matching them up, it’s slightly small on the clone tha port end threads were also not like original. Pumped it up and started leaking, I think most of it because the threads are not screwing in as a match! Slightly loose, I haven’t tried a different o ring I’m really skeptical on using it. Anybody else maybe have gone through this counterfeit air cylinders?
 
Threads that don't match up and you still put air in it !!!!!!!!!! Not good that kind of pressure can kill. 

Guy on you tube built himself and a few others some PCPs from CO2 guns. He was werqing on one when the single screw he had in the valve sheared. BOOM and the, 3/4 inch by two inch, valve went all the way through the thick part of his thigh and was sticking out the other side. He lived but was lucky he did.

High pressure is very dangerous if things don't fit just right abandon them immediately for something that does.

Be safe do some research and understand what you are doing or, putting it bluntly, Just don't do it.
