<div align="center">MINI SPUD

Provided By - Kevin

This is my first combustion launcher and it is made out of all copper. The chamber is made out of 3/4" copper piping and the barrel is made out of 1/2" copper. I can shoot about 50 yards with propane. I use a BBQ igniter on it and it always fires on the first click. </div>

This is a combustion, not a pneumatic. No need to stop and release air pressure.

And in the second line...
I can shoot about 50 yards with propane.
