Nice
Is the bottle from a fizzy drink?

I would suggest making the barrel much longer, maybe 2 times longer. It will increase muzzle velocity by alot.

How did you secure the bottle to the chamber?

Have all the fittings been primed and glued to the pipe with the proper solvent weld?

it doesnt seem that powerful because he only had it at 10 psi.

i think it could have been more though because sprinklers dont work properly under about 20 psi

I still fail to understand why in the hell people insist on using soda bottles as chambers.

Spend five dollars more and get the real deal.

You could just extend the chamber you already have, just take off the bottle and extend that piece of pipe by about 2ft, then extend the barrel by 2 or 3ft.
I think were forgetting that all the joints between the bottle and valve count as the chamber aswell, so your chamber is a considerable size already, its just the bottle ruins it.
That looks like 3/4" pipe you are already using, so you could either stick with that, or go to 1 or 1 1/2".
