A little update, we have 32 out of the 50 of people saying they are interested in going in on the group buy. That is between here, IG, and Reddit.

Obviously would like to get above 50 to account for the inevitable people backing out as this is just verbal commitments as of now.

edit For page ownage

I need that CQBSS

@LSUJON

Your inbox is full with this group buy! Put me down for one as well. Thanks for doing the work to line this up.

Got you down but dont thank me yet, still far from happening lol

What is this GB and what all does it entail?

I reached out to someone at AAC about M4-2000s in FDE before I even saw this thread today. I’m just gonna say, perhaps have your wallet ready. You didn’t read this here. And you do not have any idea who I am.





You’re welcome.

I'm in for one of those AAC cans. Can whoever is managing the list add me?

I guess the sandman is for the 300 blackout only? Are the problems really that widespread with 556?

Yes.  Dead Air suppressors can’t handle the 556 rifle round for any serious use/warfare.   Seems to work fine for the 300blk….so far I’d say….

@LSUJON

Definitely in on the GB if we can make it happen

Kevin Brittingham, is that you?

Lol no nothing they actually said there was a group buy interest here and said there will be a run of them in the coming months just not confirmed on the date yet. But you didn’t hear it from me or my “source”.  I’m a nobody. But my wallet is ready.  So it looks like whatever LSUJohn and the other IG people are doing it’s legit and working.

Forgive my ignorance - who uses FDE M4-2000s?

I believe they’re switching to a version of the M4-2000 (416) on the 556 guns now.

On the 556 Noveske guns?

Yes. Could be mistaken and the 416SD might be a completely different kind of suppressor. Haven’t looked too deep into it but aren’t the baffles the same they just have an fde coating and engraved with 416SD marking?

Besides markings and the occasional endcap difference (stepped/slick), current mod 8 m42ks and 416sds are exactly the same.

So, they've been using black M4-2000s on their 556 Noveske uppers (from the pics I've seen) - are they are now getting FDE M4-2000s?

And hence the interest in a group buy for FDE M4-2000s?

NSWDG has used the AAC 416-SD as their contract 5.56 suppressor since 2007. When the new carbine contract was up for competition, a new suppressor was part of the deal and the Dead Air SMS-MIL was selected at the same time as the Noveskes. This was during the time that AAC was somewhat non-existent because they got wrapped up in the Remington bankruptcy.

Fast forward a few years, the AAC brand and company leftovers were sold to a private equity firm and they "restarted" the company. They kept a few of their older designs alive that had ongoing mil contracts/orders as well as introduced some new ones. It's been reported that there were some issues with the contract Sandmans and so there's speculation and evidence that some of the guys just threw their 51t mounts back on the Noveskes and started running the 416-SD again instead. Now that AAC is restarted it's not a dead end they're able to get fresh cans & repairs done, so the situation sorta resolved itself.

In 2008, the M4-2000 was updated to the exact same design as the 416-SD. They kept the different model numbers so they could update them individually if they needed to, but there were no changes made after that. They did update their coating at some point in the late 2010s (to Cerakote) and they also updated their end-cap welds to be stronger, but otherwise an M4-2000 and 416-SD is essentially the exact same suppressor other than the markings. Think of it as the same difference between an Ops 12th and AEM5.

When the "new, restarted" AAC fulfilled the latest order for NSWDG of 416-SDs, there's some evidence that they were coated FDE instead of Black this time. So hypothetically we could start seeing pics of Noveskes with factory FDE 416-SDs on them. In which case a factory FDE M4-2000 would be the closest stand-in can you could use.

The only main difference between the old AAC 416-SD/M4-2000 and the "new" AAC 416-SD/M4-2000 is they're using some shitty engraving style on the cans that looks like it's been gouged out by a 5 year old, which is unfortunate. There's no real evidence yet whether or not the new ones will be just as robust and just as QC as the old ones, only time will tell. But presumably since the company is operating full time now, even if there are issues, they can be repaired. They're also actively accepting repair orders for legacy "old AAC" cans as well which is super nice for those of us that own em.

Thank you dude - much appreciated for that write-up. I've seen parts of this story sprinkled throughout the thread - was just having trouble understanding the big picture and connecting all the dots - that helps!

Yes much better explanation than I gave, I apologize. They aren’t necessarily “switching to them” just going back to them after some reported issues. I’m not on the inside so I have no idea just what’s been floating around and what this great explanation has said.

All good - you were informative as well!

Who do I send my nsr to get the closest to factory Noveske fde from a matched receiver set as possible?

You could ask in the Refinishing forums.

Presample Depot has done phenomenal work with cerakoting a lot of devgru clones as of late. Shoot them an email to see if they would do just the handguard for you. But know that it may vary from your receiver set slightly. Also to note that the noveske receiver sets are done in H-265 and the devgru guns are done in HIR-265 (infrared coating) . So if you want to keep it all uniform, you’d have to do H-265 with hardener 12:1 ratio to get the same look minus the infrared capability

Complete uppers back in stock!


Noveske Gen 3 Complete Upper 10.5” 5.56 Shorty

Is this place legit?

If it is I apologize!

Absolutely.

Cool deal I’m gonna check them out!

Big vouch!  The best!

Little help. What page is the list of correct parts for the noveske build.

Thanks!!

Now do lowers

Anybody have any more info on the sandman not working with 556 info from DEV?  I always assumed it was because the sandman sucks with flash at night, and considering 98% of what they do is at night, I could see that being a major issue.  The m4-2000 owns the sandman in regards to flash.

So far we only have data from LSUJON stating his end cap was coming loose. So I’m imagining with Dev’s shooting schedule they were probably blowing off end caps routinely and that would surely sour their confidence in the can. I’m surprised it wouldn’t happen with .300blk but maybe it has something to do with powder burn. I’m just speculating though.

And 2keylows's and JohnnyUtah427's end caps

I have experienced the same thing with the end caps as well.  Assuming they were able to 100% fix the “endcap issue” I could still see them putting it down for 5.56 use because of the flash, it’s that bad.  Especially with full power ammo.

Same here. "Bigger" flash when compared with other cans, this is with a swapped 30cal flashhider endcap and various 556 rounds; but a 30cal for 556 can only do so much.
Tbf, Dev is probably using a special sauce 556 round to further mitigate.

Kinda makes you think the 300blk version was the main focus, with the 556 version being the afterthought.
Fun to speculate.

Weren’t the 5.56 uppers supposed to be training uppers? They got stockpiles of 5.56 to train with.

No, they have 5.56 uppers, .300 uppers and there are pics of a sim-only upper. The sim-only upper had a training suppressor that was FDE with an FDE end cap which it where the black vs. FDE end cap discussion came from.

My end cap has worked lose as well. In addition to that, shooting my 16" BCM KD4 upper at 100 yards, the groups would open up several inches every time the can was put on. It was horrible. Take the can off, shrink back down, put the can back on, 5-6" groups. Shot with MK262.

On top of that, I had one of the SMS cans that needed to be re-cored. Posted about it here and a DA employee called me a liar. As a company, I just can't support them anymore.

There is still live fire training, which is where the 5.56 upper comes in. I think I saw a story where the GBRS guys talk about live fire training in their days at that command and they stated they used ball 5.56 ammo for training.

Well, another DEVGRU is born. Take #2 for me - the first one had the wrong mix on the cerekote and all the anodize blasted off. Not so this time, and went with HIR 265.

I have everything to make it clone correct, including the deadair. Just wanting on.... you guessed it, the stamp to SBR it.

Which barrel do you have?

Lol

Something about this section of barrel doesn't look quite right.

Man you guys have some serious autism. Lol It’s a CQB barrel out of a shorty or GB. I think Noveske profiled it wrong and thats whats up with the step.

I have a LW 5.56 barrel that will go in it.

Very nice!  Who did the cerakote for you?

Friend of mine did it.

I figured out that its a Noveske "no gas block" barrel - thats why the step. Its for a FSP if you choose to run one.

It's getting swapped once the stamp hit anyways.

Haven't shot it yet.  Need to get it to a range and get sighted in soon.   Sure is pretty tho lol
