Description
Dead Air built the Lazarus 6 for people who run their rifles hard and expect their can to keep up. It is additively manufactured from Haynes 282, a nickel-based superalloy borrowed from the jet engine world, which is why this suppressor carries a full-auto rating with zero barrel length restrictions. Bolt it on a short 5.56 pistol, a 6mm ARC precision build, or anything in between up to a 6mm bore, and it just runs. At 5.88 inches long and 1.63 inches in diameter, it keeps a compact footprint that will not turn your carbine into a boat anchor.
The Triskelion Difference Inside the Lazarus 6
The internals are where this can earns its keep. The patent-pending Triskelion Gas Management System uses baffle geometry that is only possible with 3D printing, venting gas early and flowing it forward instead of dumping it back through your receiver. That means less gas in your face, less carbon chewing on your bolt carrier group, and a smoother shooting experience overall. It also tunes the report toward a deeper, lower-frequency tone that is easier on the ears than the sharp crack a lot of steel cans produce. The design even pulls heat from the core out to the outer skin, so it cools down faster between strings of fire.
Xeno Mounting on a HUB Foundation
This version ships with the Xeno adapter and Dead Air's DA129 1/2×28 three-prong flash hider. The Xeno system uses tapered, left-hand threads with a two-shoulder lockup, so the can seats snug, returns to a repeatable point of impact, and will not back off when things get hot. Since the Lazarus 6 is built on a HUB base, you can swap over to KeyMo or direct thread down the road if your setup changes. The front cap is replaceable too, and it accepts Dead Air's R-series caps including the E-Brake.
Why the Lazarus 6 Earns a Spot on Your Rifle
Independent testing has backed up the low back pressure and balanced suppression claims, and reviewers consistently note minimal point of impact shift across multiple hosts. If you want one durable, quiet, low-gas can that covers everything from a 10.3 inch SBR to a 6mm ARC hunting rig, this is a strong way to spend a tax stamp.

Frequently Asked Questions
Can I run the Lazarus 6 on a short-barreled 5.56 rifle?
Yes. The Lazarus 6 has no barrel length restrictions and is full-auto rated, so it is at home on a 10.3 inch SBR just as much as a 20 inch rifle. The low back pressure design also means short-barreled guns run cleaner and softer than they would with a traditional baffle stack.
What calibers is the Dead Air Lazarus 6 rated for?
It handles anything up to a 6mm bore, which covers 5.56 NATO, .223 Rem, 6mm ARC, and other 6mm cartridges. That cross-cartridge flexibility makes it a great single can for both a duty-style carbine and a 6mm ARC precision or hunting build.
Is the Lazarus 6 Xeno version compatible with other HUB mounts?
The suppressor uses the industry-standard 1.375×24 HUB thread on the back, so you can swap the included Xeno adapter for Dead Air's KeyMo or direct thread options. Dead Air does note that some third-party HUB accessories may not fit correctly, so it is safest to build your mounting setup around Dead Air's own adapters.
How does the Xeno mount attach and hold zero?
The Xeno system threads onto a matching three-prong flash hider or muzzle device using tapered, left-hand threads with a two-shoulder lockup. That geometry keeps the can snug under sustained fire and gives you repeatable point of impact when you take it off and put it back on. Reviewers have consistently reported minimal to no zero shift across different hosts.
