I have settled on building a coaxial, for its compactness for combat use (Yay). I have settled on a 1.5 in barrel and 54in long. I only want the barrel to extend just outside the chamber, at most 4 in. I need to know will the gun still operate if 50in of the barrel is inside a combustion chamber 54 in long, for a total of 58 in in length?

It will but it will perform poorly. According to whatever studies were done on coax combustions, they seem to lack more power than a conventional combustion.

Damn! I will have to raise the diameter of the chamber

Or just build a pneumatic.....
in which coaxials are more common and effective.

not an option, i have a pathetic air compressor, and pneumatics arnt as good for a battlefield, which is my hope for the spuddy im building.

So that explains why most paintball guns are pneumatic in operation


Pneumatics are far better then combustions on the 'battlefield' until someone builds a working full auto or semi-auto combustion.

How crappy can your compressor be? You can charge a pneumatic with a bicycle pump.
