Good point. The correct movement is all there, but the timing is just a hair off, as you mentioned.

I'm calling it a FASOR.

IIRC automag bolt springs wore out after a while and would stick. Care to elaborate?

I have the same bolt spring in my mag that it came with - 9 years ago.

There are also tons of hammer-spring type guns out there that don't seem to have problems.

Idk if this had been resolved or not but I just saw this today

Jack says "technically it's a spool"?

It comes down to nomenclature. The paintball world seems to have locked onto a poppet valve being a separate mechanism to release air, and a spool valve means it is built into the bolt. In the rest of the world (ie. pneumatic/hydraulic industry) this is not the case. Poppet=face seal and spool=axial seals. I guess any more arguing won't really make a difference, I'm just stating my opinion, take it or leave it.

For more clarification,
Read xluben's posts on this thread. He explains why there's so much confusion and why it's technically spool...

I can't imagine why PE calls the shuttle thingy a poppet when this gun is very definitely a spool vale design. PE knows the difference so go figure.

Below I have animated the images from the manual. A few of my comments on the operation...

• This is a spool valve.
• It is not based on the GEO drivetrain.
• It is not a poppet valve.*

*All of the seals are axially sealing o-rings. There are no face seals (or "poppets"). The manual chooses to call the center stalk a poppet, but it is not actually creating a face seal.

Two key features of this design are the fact that it seals the dump chamber when the firing sequence is initiated, and it that it has a 2 stage bolt speed profile (starts moving slowly and then rapidly speeds up on the second half of its movement). The first is important because sealing the firing chamber is critical for efficiency. The second will allow the gun to deal with misloaded or jammed paint very well.

Enough comments. Here is the animation:



Edit: Found a better animation online. No idea who made it



Edit 2: Even better animation from lentyay. Thanks!



Here's a quick rundown of the operation (taken from the manual).









And a more succinct description from Uziel Gal:


I hope this clears up any confusion...

Nice info , can't wait to get a etha

[iboomalot]

That engine kinda reminds me of the Vcom design by BL.

Vcom is a spoolie and would save that engine is too.
