I'm looking for a wooden mod too...phidias look pretty cool but I don't know if I could deal with the feed system...
some times the simplest things can seem complicated.....
really its quit easy.. to feed... i only "invert" it for priming..
the rest of the time i "fire n feed" wich you basically use the feed and the fire button at the same time time..
its really nice never flooded and always wet.
if the Phidias isn't for you the chances are there is one some were out here on the threads....
