well your tigger needs to pivot from the top left side, looking at it side on. so when you squeeze the trigger it will push up,pushing in on the valve button.

if you imagine that you make a tigger that attaches to this valve, and pivots where the roller arm does. this will give you the realistic feel of a rifle. looking at the picture, i do mean the button on the valve pointing downward

thank you I think I have it if i replace the wheel with the shoe of the trigger as you pull back on the shoe the lever will pivot upwards working the valve button. correct i hope

Hey guys,

Thank you really much for those helpful comments!
Actually I´ve found out how a hammer valve system works.
Maybe this is the best and good looking way for a good airsoft sniper
So I guess I´m trying to make a hammer valve to operate the gun
One problem is that I dont know how to make the hammer valve semi automatic :S
Can you guys tell me how to make a hammer valve semi auto?

Thanks alot!

Google "double action trigger"

Seems like the easiest way.

( net als sommige klappertjespistolen.Elke keer als je de trekker overhaalt gaat vanzelf de hamer naar achter en achteraan schiet ie los. Zo kun je steeds je hammervalve open tikken)
