Nice.
Though you could check out the "C:B" ratio the next time you build a gun.
For more information, click Wiki at the top of this page.

How are the barrels connected to the chamber?

Question is, what do you want to improve?

Probably performance, ofcourse.

Hey so the Barrels are screwed into the chamber.

And were hoping to improve mainly fire rate.. Its really un reliable
We bought a good sparker for 15$ but it still seams to only shoot when it wants too.

Fire rate? On a basic spray and pray? Sounds like you're looking for consistant shots.

You're probably using too much fuel, a problem much harder to overcome with a smallish chamber like yours. Mutliple spark gaps and a fan can help with consistancy...assuming you get your fueling down pat.

You can come close to tripling your ammo performance with a (lot) longer barrel...4-5' or so.

Chamber fan and propane metering would do well on firing rate, performance and reliability/consistency.
