The full gun

close up of the modified head for trigger/air input

The machine screw had to be put there because there was a pressure relief hole there, which would leak otherwise

a view showing the bent magazine for a clear line of sight down the barrel

The modified brass bushing i had to use because the siphon tube which was originally there snapped by just touching it, i needed a way to keep the trigger spring in place, so i turned it down till it would fit.
