Any other stuff I have to buy to fit on my Steyr LP10 cylinder?

That will generally do it.

A full tank will give 50 refills according to vender.
Educate me on this.

Started out with 3000psi, each LP10 cylinder volume is what? 50cc? So after using up 50x50cc=2500cc what would be the psi at that point?

I still need a functional hand pump to top it off to 3000psi after each cylinder refill, correct? Less in beginning, but definitely more once psi get down to 2000psi, correct?

You are making this way too difficult. Ok, it is true that every time you fill your cylinder, the tanks equalize to each other. Each time the pressure will a small bit lower...... Big deal, you will get to the point when you feel you dont get enough shots from a fill, and then you refill your tank at a dive shop...... You don't need to pump up your cylinders unless you are a masochist. An 80 should easily get you a year of shooting. So just keep it simple.......

You are over thinking this to buggery.....
The pistol tank max is 200 bar. (2940 psi)
The pressure reducing valve works at approx. 55 - 80 bar.
So a empty tank already has at least 55 - 80 bar in the tank.
You do not need to fill to 200 bar everytime.
200 bar is enough for 2 full events plus finals.
Use the dive tank to fill using the head pressure down to about 140-150 bar (still gives near a match quantity depending on your velocity setting.)
The dive tank can be used down even lower to about 120 bar if you refill during a match, for training who cares.....

"According to Steyr...
"The air for actual shooting is drawn from the compressed-air storage cylinder and reduced by a reduction valve to the steyr pistols working pressure of about 55 bar. According to Steyr air pistol their compressed-air cylinders have a storage capacity for about 180 shots."

Any reason you’re not concidering a 300 bar tank?
Mine is 8 liters and will last ALOT of fill ups.

I highly recommend his tanks. I have two. I use one to top top the other one off and supply my air rifles
