which valve

[jalord159]

hi guys im currently building a bb sniper. it will run on some form of solenoid valve and have a simple 555 to quickly open and close it.
however i cant find a small valve that would work, how does this look:

if your going to use it for air flow, yea it's a little small, (if your barrel is bigger), if it's for bb loading as long as the bb's roll through easy, it's perfect--MABY<get it thats a big maby, let us know how it goes
