semi/full auto bb pistol

[wyz2285]

Thanks to JSR's valve less design, I built this semi/full auto pistol. Really like it makes me remember the magnum:D and looks like the first semi/full auto pistol around here .The barrel has a suppressor and a 1/4 male connection to a additional silencer, the gun is a mod blowgun, now it has much more space for chamber Haven't get a shock pump yet, so only tested at 100 psi, for 2 semi shots
Don't have a video right now and I'm not sure if I will make one because a lot of people will ask me how it works and a how to video.

Lookin good dude... Is it barrel loaded?
I'm guessing u drilled out and sealed the handle to make a bigger chamber space?
Would make a nice little portable few shot gun..
Good stuff

The thing I don't like is the dead space betweem the valve stem and the actual barrel. Also, what size is the barrel? It looks like a regular pipe nipple.

Very nice! Needs higher pressure for moar powah/shots per fill, or you could connect it to a paintball tank via remote line

The thing I don't like is the dead space between the valve stem and the actual barrel.

In this case, it's not dead space because in the valveless/pop-off principle that space between feed valve and breech is actually the effective chamber volume

Yes you are correct

[Vincenzo]

@JSR I thought the space between the schrader valve and the valve stem was the chamber.

@JSR I thought the space between the schrader valve and the valve stem was the chamber.

And it's the chamber ask JSR for details

That's what I thought. So, the space between the valve stem and the barrel is dead, correct?

[saefroch]

No, it's not dead space. Dead space is the volume between the main valve and the initial projectile position. In this design, there is no main valve, the projectile acts like the valve. Therefore, zero dead space. The space that you're calling dead is the volume that depressurizes to force the projectile down the barrel (effective chamber volume).

This may just be a semantics confusion...

Sorry, I was not aware of the detent.

[jackssmirkingrevenge]

Glad we cleared that up

[wyz2285]

But to trust me it's no easy to make that perfect seal detente

Ah, very nice, simple and clean. I really do like the simplicity of this particular build. It really is a shame that you don't have a shock pump yet, I'm interested as to how loud it is.

I am assuming you mean on youtube?
