Saw this on reddit a but ago. One of the quickest "quick-change" barrel options I've seen. Uses all the important AR15 parts. Will have different handguard lengths available to match your barrel length. Saw one of the guys say they will be offering a builders kit as well.

Unfortunately it is likely a year out.

Senex Bullpup Rifle, brand new from Shotshow 2022

I haven't found anything mentioned at all about that. This is a very early 3D printed prototype from what I've read on reddit, so it's probably still a long ways off on pricing.

I'd rather have it use a short stroke piston like a Bushmaster M17 rather than the direct impingement system, (especially as the bolt carrier is Very much like the M17s.)
How it responds to being manhandled in the field will be interesting to find out, there seem to be a few fiddly parts on it.

It has a lot of potential, but I hope they do more refinement before they even think of releasing it.  The barrel release is...concerning given how easy he unlatched and move the release handle.  Beyond that, my only negative would be that it's direct impingement and I'm not sure if I want that gas right under my nose.

Yeah the DI system is a little odd to me on a bullpup, and concerning when considering suppressor use.

Id like to see a working version and showing off say..5 rounds then the barrel swap to say 300 blk..
Is it fully ambi?

I think with the quick change handguards (not in the vid) it should be lowered to the top of the trigger guard (looks like the cheap Turkish shotguns otherwise)
Butt stock could also come down a bit.
Would like more info on weight, Accuracy, durability of the quick change system.
Verification that it works with several common caliber options..(22..223..300blk..6.5grendel..and for fun..458 Socom!!)

Kinda sad this wasn't a fully functional model..Reminds me of Desert Tech circa 2014.
(I.e we got a 3d printed prototype but no functional firearm).

Same. But it needs to be that way to work with the AR FCG due to the linkage i believe. This is what I came up with in paint. more of a angled grip/fascia attachment for the lower MLOK. I also think the buttstock needs to drop down a bit for taller shooters.

I admire the work he has done, but the rapid printed non functional gun, and total lack of a booth suggest it may have a tough time making it to market.  I have seen a lot of great ideas that just don't have the oomph behind it to make it to actual production.

We have no connection to the work done at Senex, but I wish I could show you guys some of the stuff we have done under NDA, I am hoping some will make the light of day at some point.

Given it looks like its got enough room for it in the handguard, a short stroke piston and an impact surface gas block might not be that hard to engineer in the aftermarket.
One benifit to the AR gas system is that it pushes the bolt forward against the barrel during unlocking which reduces strain on the locking lugs as long as your gun is timed properly and not over gassed or under sprung/weighted

make the fore end an M-lock accessory.  That way those who want to mount something else in that space don't run into the Tavor SAR issue [Pre X95/T7 covered rail system]

Only issue with dropping the buttpad down like that may be the position of the bolt release and trigger pack removal.  A solution would be to have the supports wrap around the removable button catch button, which would also help "fence" it for protection from the side.

I spoke to a friend of his recently, this is so early. Trade mark was only done late last year and the site wasn’t even up at that time. All I hear is that they have it all figured out and it will hit by the end of this year. I hate to rain on his parade, but no way. It’s so early and a single hiccup that isn’t caught in this phase will cost tens of thousands maybe the company like we have seen recently in other manufacturers. I hope he follows his dream and pulls it off, but I think it’s a very long shot in a crowded market. Mdrx, x95, Aug, m17, keltec, and now Springfield. I don’t see how this will fit in.

Part of that will probably depend on manufacturing costs and end-user cost. Save for the Keltec (and are the M17s actually for sale?) most of those are above $1500, closer to $1800 or $2K. If the cost of making them doesnt run the price up to those levels, they... could have a chance?

By far, the biggest selling point I could see is the partial AR parts compatibility. But how much that helps is debatable.

i was wondering how long it would take for someone to do this. so many not-AR18 and not-AK bullpups, you'd think using actual AR or AK parts in a bullpup would be obvious. or in any new gun design for that matter. why redesign something when you already have off-the-shelf solutions?

Needs some asthetic love. Be nice if they made the rear portion more triangular instead of a semi circular. That’s one of the best features of the aug. Its like the much later VLTOR stocks and very comfortable to get a cheekweld.

Agree. No reason to re-invent the wheel in that respect.

I think using AR barrels, FCG, and BCG will keep the initial cost down, plus long term economy of wear/replacement parts.

Because of this, I can see .mil being interested, as the repair parts supply chain already exists.


Interested in the concept and will be watching

it uses a proprietary BCG, otherwise it wouldn't be able to cycle. i imagine it's like the FM15 bcg.
i doubt that the only thing preventing the military from buying a bullpup is whether or not it uses AR15 parts.

It sounds like the bolt carrier is the only proprietary part, the bolt, cam, and firing pin are common.

Looks like a cross-eyed Aug mated with a Strike Industries handguard. They need some design help, that's for sure.
