Just saw the announcement on their Facebook page.  Looks great!  Wonder how much?  And when?

Wonder what bolt mods it requires. Unless you have a bunch of mp5 magazines, I don't see the appeal other than aesthetics. POF mp5 mags are $30+ and surplus HK run the gambit but larger online stores have them at $60 plus. But you can do better time to time. Wonder how it will run on the MKE polymer mags or the U.S. Made ones.

QC10 has done a great job filling a growing market desire

18.99 for korean MP5 mags, probably have to try a few to make sure they work, but I think this will look pretty cool.

It's about time someone did this.  Colt pattern mags are running $30, used MP5 mags are/were $35, $50 new. I have 2 Colt pattern and around 25 MP5 mags, so an AR/mp5 combo makes perfect sense to me. As far as the cheap Korean mags, I only have (2) but both of them run great! Hopefully the Q model will be affordable

Now make one to take MP5-10 mags so I don't have to
That way I get BHO (unlike greasegun)
And easier feed for DI than a Glock.

Glock mags are still more plentiful, struggling to see the point of a gun which uses very expensive magazines, and as I can see it, no advantages over Glock.

Well.....glock mags are angled back, colt mags are straight, and now we have Hk curved forward.............now were complete with mag shapes.

The advantage would be for someone who already has a lot of MP-5 mags or wants metal mags rather than plastic.

Bingo. I'm trying to keep my assortment of firearms simple so I don't have two dozen types of magazines and zero spare parts for any gun.

I wonder if a typical ar 9mm bolt will work or if it has to be modified like the glock bolts.

Because you don't have one yet?




Because you may not want to break out your $30k machine gun to go to the range to shoot a 9mm rifle when you can shoot your sub $1k semi auto gun... especially if your shooting location doesn't allow full auto.




As previously mentioned....




Because you don't want to have multiple types of mags on hand that can be mixed up.




Because MP-5 mags are a whole lot easier to load than Glock mags.







Note: I want to get a 9mm AR but I'm undecided on the mag issue as I have both a MP-5 and 9mm Glocks so I already have mags for both.  I'm leaning towards the MP-5 mags because I have more of those than Glock mags, because the angle of the mag sticking out of the gun looks weird and for the reasons mentioned above.




Anybody make a 3 lug 9mm barrel?

Why this QC10 configuration?

I have a HK94 clone, so i have the mags already and dont own a Glock or Colt SMG firearms.
Also, the MP5 mag shape is the most attractive to me of the three options.

You already have an HK94, why would you want this?

Because I want the ability to use a Slide Fire stock!!! Plus my clone is fullsize, This gives me a chance at a "K" style gun.

But you wont have last round BHO, doesn't that suck?

Neither does a MP5, i'll just need to get a BAD lever so the manual of arms are similar.

I just heard about this...but went ahead with the Colt version. Partly aesthetics (I like the look of my MP5 mags in my MP5 clones, but prefer the straight mags on this) and also that the Colt version has the last round bolt hold open, something the MP5 version lacks. I just asked on the TROS 3-lug barrels and looks like the next run is in about 6-8 weeks.

I would think its probably going to be a month or two, if there are no gremlins in the lower. They said the prototype lower ran great so that is a very good sign. I really want to see the mag release and the internals of the lower. I will be purchasing one of these lower and one of the uppers when they are released. Maybe we can get Q10 to chime in and let us know more specifics.

Even though a Glock lower makes logical sense for me (common mag style to side arm), I would FO on the MP5 lower.  Mag angle looks so much better.

How it looks isn't relevant to me.  The fact that MP5 magazines are built to feed a SMG matters.  Double-stack mags are always easier to load and they tend to feed better too.  And even though aftermarket Glock magazines seem to have issues staying locked into my QC10 GSF lower, the MP5 magazine catch system shouldn't be a problem at all.

Now here's a question:  Are MP5/40 magazines similar enough in size the MP5 9mm mags that they would fit in the same magazine well?  I can't find anything on this online...

MP5/40 mags are completely different and are much larger than 9mm MP5 magazines.

That would be sweet with a DI upper and maybe a 8-10" barrel. Too bad the mags are so pricey.

Maybe I have a RDIAS to go with my Fleming wear and two MG's are better than one. Also Colt pattern 9mm mags suck compared to MP5 magazines.

Good point.  I read on a popular Maryland based gun forum a post from a gunsmith, or someone who claimed to be one, who said out of battery discharge was a risk in a 9mm AR.  Would not surprise me if the guy had no idea what he was talking about.

I had a round go off well out of battery once when the round got stuck on the ramp and the bolt hit the primer. It surprised me, but didn't hurt anything.


I'll look for pictures later.

more i think about this the mmore it seems tarded.  whole point of a 9mm ar is to be an easy conversion of a gun you already happen to have, maybe whilst deployed or so you can make it work w your RR or SBR etc.  but it is a compromise w itss blowback function w its heavy recoil, broken hammer pins and bolt catches etc.  a mp5 is better in every way than a blowback ar w mp5 mags.  MP5 is quieter, softer , more reliable.   a big pile of mp5 mags is a good reason to by an mp5, not make a new dedicated complete weapon AR lower.  

now if someonw made 9mm ar upper w the delayed blowback id be all over it like white on rice
