I think that you should not mix everything and that it is necessary to compare the weapons of the same category: PAC with PAC, hybrid with hybrid
If I change the reservoir I can fire in 300 bar (4500psi) but at the moment I am going to put in it a standard lined in calibre 45
sure, but all I am saying is - > you'd get (at a given pressure) twice the power from a hybrid (more or less)

Good looking build!

I wonder why it does SHHHH in stead of BANG though...That reservoir is huge compared to that barrel so...what's happening in there?
Did I miss the suppressor?
Maybe the new burst discs will do the trick.

We are several to notice that, but his don't see anything ^^

I think the chamber is enormous compared to barrel, and 120 inclue much air, it's longer to leave barrel.

The room made 0.47L, the gun 14mm int and 100cm length thus a volume of 0.154L
I know that there is much air but it is desired

If you can handle the extra length, get a longer barrel you 250cm would make it a lot more powerful and a little bit quieter.
