I think it’s likely that for the Mojave and now these new additions to the Nomad series along with the Lazarus 6 that they at least have a second subcontractor. I don’t think that KGM is in the DMLS game, so they’d have to go to someone else by necessity.

Nice video.   Just when I hoped I was done buying cans!

indeed. From watching the video on my (small) phone, there are two likely possibilities for how it works:

A:\ there’s a narrow outer bypass annulus that feeds into the adjustment thingy, and the gas has the opportunity to flow peripherally-centrally through the adjustable ports, and then forward and out through the peripheral ports and central aperture. Like the Helios, that’d make it a LBP can that can be converted rapidly to a normal flow-rate can.

B:\ the baffle stack has low bypass/normal resistance, and the gas is moving from the central bore into the adjustment device, peripherally through its ports, and then out through the central aperture and peripheral vents. Like any traditional can with swappable endcaps, that’d be a normal-gas silencer that can reduce the endcap’s resistance, like DA’s other cans with the E-brake, or a Rex can with their brake endcap. The degree to which this is effective is dependent on the resistance of the baffles. So, a .458 Rex can will show a greater delta than a .224 Rex can by switching to a less resistant endcap.


if it works the way I described option B above, then I think that’s likely. They seem to like parts compatibility in their previous cans. A third option is that it works like option A on the L6, but option B on a Sandman/Nomad/whatever.

Its an intriguing approach, that I’d like to look closer at.  

Per their instagram reels the ABD will only function as designed on the Lazarus 6.

Edit:  I guess the answer was more vague than I remember.  “Can the ABD help older cans?” “The boreas ABD is exclusive to the Lazarus 6 for now.”

That makes me suspect that it works via option A in my above post.

It looks more like option B to me.

3 piece design (according to the vid). Inner core that threads in like all the R series end cap (same threads according to vid), adjustment ring, and outer cap/housing.

To me it's just a removable adjustable flow/peripheral port end cap. So sorta like the KGM adjustable port end cap but doesn't use tiny set screws and can't tune each individual peripheral port.

It should function just fine on Dead Air's other cans.

Looking at those pics, I think you’re right. If the threads are compatible, its min-to-max effectiveness would probably be similar to the regular endcap on/off, with less sound consequence than just taking the factory one off.

People do often report a reduction of blowback with the E-Brake without hurting sound performance, and I suspect that this effect would be similar, with length/weight being the main downsides.

Automatic disassembly is a feature, not a bug!

The claim is 30% pressure reduction from baseline, but that's for this can, which is more of a "flow" design. How effective the ABD is on a "traditional" baffle can is unknown.

i was able to get some of the new nomads expedited to me. i was told theyll be here in about 30-40 days. i dont think i ordered any lazarus cans though.

i will for sure take a pic of the blast baffle and post it. ill compare it to my nomad L. i really like my nomad L, i just wish i bought it in Ti. so maybe ill pick one up.

when you do, (edit: blast chamber) dimensions will be appreciated. I may have those earlier, and will post if I do.

They still haven’t posted length and weight numbers for the Lazarus.

I’ve gone back and forth with DA CS via email for a few days, and they're coming up with every imaginable excuse to avoid answering me this, the last reply citing concerns of premature wear with third party mounts. I’m going to take a few steps back, and maybe reconsider a couple years after release.


Edit: they’re now saying that the reason they insist on not answering the question until I tell them which not Keymo/Xeno mount I use because: “if they are not coated or finished in the proper manner it will lead to increased erosion of the blast baffles.” That was in reply to me saying it was going on regular hunting bolt guns maxing out at 30-06 after they told me they were concerned about erosion.

At this point, not only have they talked me out of the new Nomad permanently, but I’m now on the fence about the Mojave I was going to buy soon. There’s a serious problem with this company.

The problem you run into is how big you have to make the bore, & how gas flow through a larger bore might disrupt bullet trajectory vs surface area vs smaller annular vents that provide equivalent total area without those negatives. The thing I notice with the ABD is that it doesn't appear to have any tool interface points to for tightening it onto the main body, raising the question of whether or not heat expansion might risk it to working loose with only hand tightening.
