Good morning, Norman, and welcome to the Forum.
Maybe try your question here --->  PCP/CO2/HPA Air Gun Gates "The Darkside"
Stay well.

He has a 4500psi gun + 4500psi bottle and zero refills from git go!


If you have $100 how much can you spend before you have less than $100?
So if you have a 4500psi source bottle, how many times can you fill anything to 4500psi?

Yup. Piledriver is a 4350 psi gun. It would not refill it completely after shooting, not even once.

Mini compressor for sure

Agreed. Compressor or 6k nitro tank.

Haven’t seen 6k tanks at PA but there’s lots of compressors everywhere

Yeah. 6 K tanks can be rented with nitrogen from airgas sources. That wasn't an implication that PA sold them. A new 6K tank starts around 1,100 bucks empty and is definitely not easy to carry around.

Yeah It doesn’t sound convenient at all

Yeah, I know what they weigh Bob. No reason for the typical smart aleck I'm better than you eye either. That attitude right there is what drives folks away and prevents folks from chiming in.

That being said, it's a perfectly acceptable solution for those that want a lot of fills for high air consumption guns. I've used them. So have many others. At no point did I state that it was easy to tote around. Jeeze.

My comment was so that the OP would know what they weigh.... not intended to slight you in any way, Matt....

Fair enough. If I took it out if context then so be it and I apologize if I took it the wrong way.

There really isn't a lot of options other than the those two that I'm aware of. Neither are "cheap", and if mobility is the primary decider then a mini compressor to fill the gun directly is likely in order.

I don't do it, but a great option for anyone that has access to a 6K nitrogen tank (like welders) is to use that to direct fill a smaller CF SCBA tank - then use that to fill guns . . . if you don't have such access, then this is probably the most expensive route, but a high quality one . . .

300bar is the maximum fill pressure? What’s the minimum usable fill pressure? I don’t care if I always fill to the maximum allowed. As long as I can fill to the minimum acceptable, the fill bottle still has usable air. If you get up to 7 shots on a full pressure fill, then you are likely shooting it from about 300bar down to 200bar. You will probably get several fills, but each fill will be to a lower pressure, so fewer shots with each fill. You might get 20 or 30 shots before the 3L tank drops below 200bar.
