Looking good!
I made a feeding block just like thata while ago. The high rof of full-auto gave me problems though.

I'd love to see it in action.
So where's that youtube link? :wink:

ok so its a 6mm ammo but a crappy 1/4inch barrel, so far only 150psi but 200 once i get my ac compressor back. power isnt the best but it does hurt through athletic pants, to up power i gonna switch to the 1/4inch 3 way valve cuz flow sucks, also i will give it a lil bit longer chamber.

vid will hopefully come soon,
and a possible aplication for this is a small rc car that i made... :D

it owuld be easier to use if you had a manual valve... hmmm but on the other hand solenoid can be useful if you want to use it to build an autonomous turret :D

does anyone have any idea how much time does it take for a 2 way valve to open and close ?? with a simple circuit that sends 50 or 100 ms impulses to the solenoid you could build a gun that operates like typical PCP airguns (hammer valve)

yes manual would be easyer but this isnt going to be handheld when done :D i know that the solinoid is quite inefficeint and i can only shoot through one side of a sodacan with .12g bbs, i will also up the pressure some so that willl help too. yeah this is going to go on a smal rc car i made and it runs on 24volts so its perfect. and i will mount it on a tilting mechanism and a laser pointer on it.
