Looks great, I like the blue paintjob. It might be nice to paint the barrel.
How is the power?

You should specify "3 inch" piston in the title, I was expecting to see a triple piston valve :D

nicely done and it looks to have good power potential at higher pressures, doesn's sound too loud at 60psi either.
