The People''s Bull-Pup - Senex Arms - IT WORKS!


I left a question there about.

Is this an ambi-ejecting gun?
Does the handguard forward of the receiver hold zero (For those with IR, Irons, or anything mounted on the handguard rails).

He does say there will be a beauty pass on it..So right now they just working on the mechanical stuff.

The explosion comes from the chamber, not the gas tube. Did you mean bullpups in general?

Since this is not a kit bullpup, I imagine this is being set up to be safe in the event of a KB.

All the other Bullpups (Tavor, Aug, Keltec, Desert Tech) all have features that make your face safe in the event of (KBs happen)
Generally this is a design choice to have the energy redirected through the magwell.

Honest question: what are the features you’re talking about especially on the AUG?

Most bullies have kaboom mitigation … but they also don’t run DI systems … DI undoubtedly has higher risk of pressure spikes

You mean the oldest bullpup in military service?

Steyr tested the AUG A1 by doing all kinds of nastiness to it and it never failed, like driving a bullet into the barrel and then firing a live round through it. Blew both bullets out of the barrel without doing any damage

Searching the forum for Kabooms in the Aug I found this( there are lots of threads on this topic)

"The AUG has a double-layer reinforced steel plate covering the inside of the closed ejection port.  It's bigger than the ejection port and held in place by the outer cover. The stock would have to break away for it to come straight out.  The open ejection port and magwell provide two huge paths of least resistance in case of an OOB detonation."

a pressure spike would make the chamber explode before the gas is able to enter the gas block, travel down the gas tube, and into the expansion chamber behind the bolt.
something strong enough to make the bolt carrier explode would also make the gas block or gas tube explode.
plus the carrier vents gas so i'm not sure how that would be an issue even if it could get to it.
it would also blow out the firing pin hole or out the front of the carrier past the gas ring.
basically something weaker will fail first.

Piston vs DI has absolutely zero to do with a kb. Where are you hearing this nonsense?

DI redirects high pressure gas to actuate the action …

Piston guns dumps it all at the gas block …

While it doesn’t matter which system is used for a kaboom to happen … I certainty don’t want a DI gun dumping all that high pressure gas right in front of my face in a bully application … slap a can on it and I bet it would become a very unpleasurable platform.

In the event of a OOB kaboom the remaining and now lower pressure (as most of it vented out the path of least resistance) DI gas will enter the upper receiver long after it went kaboom.

A real pressure spike kaboom, one that blows the carrier and bolt out of the extension, happens before the gas has even traveled back to begin the cycling process that would unlock the bolt.

The gas from a DI system has absolutely zero bearing on a “pressure spike” related to a kaboom. A DI kaboom is no more or less catastrophic than a piston kaboom.

I agree It will won’t be pleasurable with a baffle can. Gonna have one dirty face!

Has anyone figured out if this will be LH eject option as well?  That seems to be a standard option on modern bullies and it's be kind of silly not to incorporate it.

Lots of gassy piston guns out there. Probably 99% of the suppressor blow back comes out of the breach, not the gas tube. With a properly timed and gassed system, both can be improved.

If you think this uses a standard BCG where I can just slap a piston kit in there then you are sadly mistaken that is so and you clearly haven’t studied this design accurately enough prior to making that comment.

I can disagree with a DI bullpup design … as do others … it’s ok. Trust me. It’s ok to not like it.

It’s something the VHS-2/Hellion platform does amazingly well. Zero gassing out, no smell … it has been the most pleasurable firearm to fire suppressed … and I’ve shot a lot of firearms with cans.

The pressure of the gas operating the action in a DI is half or less than that of chamber pressure (depending on gas system length). If it goes boom it's going boom before the gas ever makes it back to the BCG.

While it probably doesn't happen often, a Kevlar, upside-down J shaped cover that mounts on the receiver/chamber area, would probably catch anything if it where to happen. Basically a ballistic cheek rest.

If it uses standard AR-15 bolts, couldn't it just use a drop-in left-side bolt carrier/bolt, if the ejection port is there?

True, but a 9mm blowback doesn't need one.  

More seriously, if this thing is using standard AR parts, just drop a Stag left-eject upper in there.  If the bullpup chassis covers up the ejection port, Dremel it open.

ETA:  Scrolling up, this doesn't look like the bullpup AR chassis I was thinking of, but a whole new proprietary upper.  Dremel maybe could cut the pocket?  There would be a hole on the outside of the gun...

For all we know he may just be focusing on reliable function at this point, and it could be a down the road test/evolution on his product development cycle- I am sure it is something he has considered.

Because as it stands now, this wouldn’t be viable at all for a left-hander

Also, the AUG, Tavor, Hellion all have LH Ejection ports right next to or under the face of a RH shooter. 0-issues
