Sporty 2240 shorty

17 fpe did the trick

Nice set up. I recently put the 1701p trigger group on my 1740.
I like your bottle conversion. Smaller than some I have seen.
Why bottle and reg is that?
The bottle is a 9 ci. The regulator is a Gurlleu 4500 input, in case I upgrade the bottle at a later date, 1500 psi output. Got this one this morning, will fit next to the other one in the frying pan.

Great question - haven't figured that out yet - I'm guessing 40 or so? My 1720 with the same reg gets at least 80 or so with a 13 ci/3000 psi bottle.

I've been wrestling an issue with paintball regs, and finally decided to use the one on the gun now. For some reason I can't get over 12 fpe with an 1800 psi output reg that I know works correctly after confirming on another tube with pressure gauge.

It maybe a weird combination of tube length versus available plenum? Non linear/diminished return results drive me bonkers, but I decided to just go with the 1500 psi reg, as I knew it would give me decent power above 12 fpe.
