QEV blowback mod?

[Dem0li-from-YTB]

Hey guy's me again Ive tried a few design's and idea's for my homemade blowback uzi but they didn't work so well. So I decided to use a qev this one to be exact https://encrypted-tbn3.gstatic.com/shop ... I&usqp=CAE anyways my question is, does anyone know if there's a mod that would make the qev have a blowback action maybe at the end of it?

What exactly do you mean by "blowback action"? Do you want the QEV to also operate a self-loading mechanism?

What I mean is I want it to kinda operate like Wen's for example as you see at the end of his Qev he has a tube with a plunger and spring and if you watch closely it goes back and forth as he pulls the blowgun trigger and air still comes out of the Qev's front end.

That is the pop-off valve that actuates the QEV.

I had done something similar with a commercial pop-off valve:



The movement of the pop-off pistol is brief and abrupt, I do not think you could get it to operate a blowback mechanism.

It would make more sense to harness the exhaust air from the pop-off pilot to do reloading work.

it is much better to make the drummer cock up with air that leaves the pilot valve.

That works too and is especially useful if one were making a big-bore repeater where too much air would be wasted cocking a direct hammer valve.

I have animated it to explain the concept:

Hmmmmmmmm I think i'll give this design a try, I might be able to use a bullpup design to make room for the magazine. Also would it still operate as the diagram if I were to scale it down a little to fit inside the back of the micro uzi design?

On a small scale it's not worth having a piloted exhaust valve, the hammer can open your main valve directly:
