6mm Full-auto

I thought I´d like to have a QEV+pop off full auto as well, so I bought a pop off and modified a QEV to use it.
It was very un-reliable, so I looked for a better pilot valve, The BTB snapvalve
Guess what, it worked
By adjusting the spring tension, I can have different ROF and power (high ROF low power or low ROF high power).
It rocked off the blow-forward bolt and barrel so I didn´t get a chance to shot it but soon...

Now:
I want a blow-back reloading system, but got a problem: How do I keep the bolt shut when the projectile is inside the barrel and open the air reach the piston that is attached to the bolt? Take a look at the diagram you will know that I´m talking about.
I think I will need to find the right spring and play with the area differential between the bolt (barrel ID) and the piston (what ever needed for the system to work). Or some short of lock system, I had one in mind but kind complicated for my taste
