I Like the design very much Mitchza!!!
Maybe a solenoid hammer could be added at some point for semi/full auto action.
OR a spring plunger could be used inside the chamber that presses the triggering bolt once proper pressure is reached for completely mechanical action.
A sleeve blocking the magazine could be attached to either as the trigger bolt is moved rearward (sleeve attached could move with it).

I was wondering what QEV that is?
Looks sleek. Like always, nice work there Mitch! 8)

Thanks a lot Thunderman. I'm sure I'll come up with something that works well.

Twizi, I have no doubt that this trigger will work perfectly in your application.

i just received some QEV's like yours from bellpro.. and was very disappointed :( i haven't tried em yet but the port holes are tiny (1/2" threads but the center hole is about 1/4" although i think it could be opened up somewhat) and they also sent me one that has no thread on the output!!! but i will be trying this type o valve on one soon

I'm afraid the majority of QEV's are like that. The output is a fraction smaller than what would be 1/2'' copper tubing. The no thread on the output is a big problem though. By all means send it back and complain. Nothing will beat a well made piston valve but as far as convenience goes and functionality goes, QEV's are very good.

It could easily be converted into a hammer valve for a pcp gun.
