There are several long running threads on this already. Nothing new that I have heard of.

Looks like it's dead in its current form:

http://ingunowners.com/forums/class-iii-nfa/330514-sig-mpx-c-apparently-nerfed.html

Well, it looks like it was too good to be true. After falling off the radar for a year, Sig released an updated video and pictures of the MPX line that is supposed to be going on sale shortly. The MPX-C no longer has the monocore baffle stack/muzzle brake to take it out to 16" (allowing you to purchase the screw on suppressor tube that is the registered part and turning it into an integrally suppressed carbine). Apparently, it has been reduced to having an 8" carbon fiber extension that is permanently attached. They plan to initially release the MPX pistol and SBR variant, then I assume the nerfed MPX-C later. The full auto sibling of the MPX-C is going to be released as the MPX-SD (to military and law enforcement only of course).

From some rumors posted on a few other sites, the talk is that the ATF put the kibosh on the MPX-C, saying the muzzle brake constituted suppressor components.

I have to say I'm pretty disappointed. I might consider buying the MPX-SBR or the MPX-P (pistol) and then turning it into an SBR. But I have no interest in the MPX-C anymore. You'd think they would consider releasing a semi-auto SD model for those who wanted the MPX-C. Still a single stamp, same as buying an integrally suppressed rifle. With the SBR, that's 2 stamps, one for the gun and one for a suppressor (though I guess I do already have a sub gun can that would probably work perfectly to put on the MPX SBR, but that's already going to be shared between several of my other guns).

I always thought it was a goofy idea.  ATF is not going to let you make something that just needs a pipe tube installed to make it a workable supressor.

The way to set this rifle up is with a 6-7 inch rail, and a 8 inch barrel, threaded to 1/2X28.  Then you can install whatever supressor you want on it.

Intergeral suppressors, while cool looking, don't have the use of a supressor by itself, that you can use on anything you own.

I agree.

I was hoping to avoid two tax stamps and ugly trust engraving. Relatively minor issues, I know. But I want a do-it-all suppressed 9mm carbine, and this looked like a good candidate.

So just buy the SBR no engraving or nothing. Saw that update in the other thread.

Does the non-select fire SBR version exist? Can you post a link? If so, that would actually be helpful information.

I went through "the other threads". No joy.

None of them exist yet so worrying about it is silly at this point. The reason I mentioned the other threads is so you could post in one of them rather than starting another thread on the same thing. It helps everyone stay current.

I have seen the SBR and pistol mentioned but until they are shipping it doesnt matter much. Sig offers quite a few factory SBR's so I wouldnt give up hope.

Question - Is the integral baffle stack still somehow inside that carbon fiber thing, but perhaps in a way where it's not providing suppression?

With carbon fiber, the term "permanently attached" speaks of hopes & dreams more than science.

They don't have them in stock, they're not even sure when any will show up. But you're right that price is tempting.

All depends on what the magazines cost.   If they are like $65.00 apiece, no thanks.

This sucks.  I really wanted the integrally suppressed one.

If that ain't happening, I will consider one of the Turkish MP5 guns that are coming in.  

Outdated design, but still sexy as fuck.

Depending on how that sleeve is attached I might be fine with it. If there are usable threads and a 6" barrel it might be perfect.

My contact at Sig says mid July is target release date. Having ATF issues with carbine. Something to do with the muzzle "devise" is a "suppressor". They will be releasing both pistol and carbine at same time. Shop I'm at has them ordered, but on a holding pattern. Sig contact is ultra reliable/in the know.

"But where did that list of six characteristics come from? The agency never explains whether those six characteristics are present in all (or most?) silencers. The agency never explains whether there are other common characteristics that do not appear on its list. And the agency never explains how many characteristics in common are necessary to be classified as a 'firearm silencer.' What if a device has an 'encapsulator' and an 'end cap; - is it a silencer? What about a device that is attached to the muzzle of a rifle, and is full of "sound dampening material," but has none of the other five physical characteristics-is it a silencer? The agency's approach leaves Innovator (as well as other regulated parties, and reviewing courts) guessing."


Would be interesting if this ruling ends up affecting the MPX-C in some way.

Was planning on building a 9mm AR. Going to wait for one of these. Hopefully in a factory SBR.

ETA: I really like the MSRP on the pistol version. Once it's released and things calm down I would imagine you could pick one up in the $1400 range.

According to OSS, the only registered part of the suppressor is the sleeve.  The turbine/flashhider/muzzle brake is not considered a suppressor.

OSS Shot 2014

The muzzle device extends a few inches forward, not like the enormous "muzzle brake" Sig was trying to pass off as a brake.  The baffle/turbine system is not a traditional suppressor design either.

I'd totally rather drop that $1500 on a Sig than a clone of an MP5. Though I've been pricing the clones for the past two months because the MP5k has been my grail gun for the last 15yrs... Are these anywhere near being released?

Amen to that!  I don't think a "copy" of an MP5 can hold a candle to what this Sig appears to be.  Save your money, as am I, and wait for the real deal.

I think if SIG left a baffle inside a carbon fiber tube and then tried to say it somehow wasn't a suppressor, the ATF would blow a fucking ovary.

Yep, baffle is gone guys. Shouldn't be surprising to anyone.

The rumor is they can't get these things to run properly. Hopefully the delay is to fine tune these things so Sig doesn't beta test their product on their customers like they did with the P250 and P290

Trigger seemed fine. Overall it felt similar to an MP5 with AR controls. Magazine was a bit stiff to load but felt sturdy. I just put half a mag through it so it wasn't much.

Saw it on one of the Sig forums a few months back when the MPX was slated for a summer release

ETA: Tried to find the thread but couldn't. Not sure if was on sigtalk or sigforum but it was in a long thread about the MPX that has been running for over a year. Honestly even if it's true, if Sig irons out the kinks before they release the gun, I could care less
