Buy the Sandman X if you want one can for 5.56 and .30 cal and plan to shoot it hard. It's the Dead Air suppressor our builders picked most last quarter, and the second most picked suppressor of any brand.
The short answer
Most picked: Dead Air Sandman X. About half of all picks among these four, and around $890 today.
- What we like: rated up to .300 RUM, full auto rated, no barrel length limit, Haynes 282 body.
- Watch out for: at 14.5 ounces on a Xeno mount it's no lighter than the Nomad, and it costs more.
Best value .30 cal: Dead Air Nomad 30. About three in ten picks among the four, around $800 today.
- What we like: 6.5 inches, about 14.5 ounces, and rated up to .300 Win Mag or .300 Norma Mag depending on the listing.
- Watch out for: Dead Air says it isn't built for the same sustained full auto use as the Sandman.
Best for 5.56 only: Dead Air Sierra 5. Around $695 with a Xeno mount.
- What we like: the shortest of the four, and full auto rated with no barrel length limit.
- Watch out for: 5.56 and .224 Valkyrie only. It won't move to a .30 cal rifle later.
Lowest back pressure: Dead Air Lazarus 6. Around $890 today.
- What we like: Dead Air's Triskelion baffles cut the gas that comes back at your face on a gas gun.
- Watch out for: the heaviest of the four on either mount.

Sandman X vs Nomad 30
These two are the real argument, and both are .30 cal cans that'll run on your 5.56 too.
The Sandman X is Dead Air's hard use can. It's made from Haynes 282, rated up to .300 RUM, full auto rated, and Dead Air lists no barrel length restriction. You can put it on a 10.5 inch AR and dump mags without worrying about the rating.
The Nomad 30 is lighter duty. It's about the same weight and length, and it's rated for magnums too. When Dead Air launched it, the company said to keep full auto use to a few mag dumps at a time and to run a brake rather than a flash hider on very short barrels.
So it comes down to how you shoot. If you run short barrels hard, the Sandman X earns its extra money. If your rifle has a 14.5 or 16 inch barrel and you shoot semi auto at a normal pace, we'd save the money and buy the Nomad 30.
Sandman X vs Lazarus 6
This one's really a caliber question. The Lazarus 6 is a 5.56 and 6mm ARC can, so it won't go on a .308.
What it does better is gas. Dead Air built its Triskelion baffles with 3D printing, a shape it says can't be machined, to cut back pressure. On an AR that means less gas in your face and less extra wear from overgassing. If you run a suppressed 5.56 and hate the blowback, the Lazarus 6 is the one to try.
Sierra 5 vs Lazarus 6
Both are 5.56 cans. The Sierra 5 is shorter, three ounces lighter on KeyMo and about $190 cheaper. The Lazarus 6 adds 6mm ARC and lower back pressure.
If you only shoot 5.56 and want the smallest package, buy the Sierra 5. If you're getting gas in the face on your carbine, or you might add a 6mm ARC upper, buy the Lazarus 6.
Mounts: Xeno vs KeyMo
Dead Air sells most of these cans with either mount. Xeno is the lighter, shorter option and threads onto Dead Air's muzzle devices. KeyMo is a quick detach mount that adds about half an inch and a couple of ounces.
KeyMo comes off faster if you move one can between rifles. Xeno keeps the package smaller. The muzzle device guide covers how mount systems lock you to a brand.

FAQ
Frequently asked questions
Is the Sandman X better than the Nomad 30?
- For hard use, yes. The Sandman X is full auto rated with no barrel length limit and is built from Haynes 282. The Nomad 30 is about the same size and weight and costs about $90 less, but Dead Air says it isn't made for the same sustained full auto use. For a 16 inch semi auto rifle, the Nomad 30 is enough.
Which Dead Air suppressor do builders pick most?
- The Sandman X. It drew about half of all picks among the Sandman X, Nomad 30, Sierra 5 and Lazarus 6 on GunPartPicker from July to September 2026, and was the second most picked suppressor of any brand.
Can I use a Sandman X or Nomad 30 on a 5.56?
- Yes. Both are .30 cal cans, and a .30 cal can works on smaller calibers like 5.56. You give up a little sound reduction compared with a dedicated 5.56 can like the Sierra 5.
What is the difference between the Lazarus 6 and the Sierra 5?
- Both are 5.56 cans. The Sierra 5 is shorter, lighter and cheaper. The Lazarus 6 adds 6mm ARC and uses Dead Air's 3D printed Triskelion baffles to cut back pressure, so less gas comes back at your face.
How much does the Sandman X weigh?
- 14.5 ounces on a Xeno mount and 16.8 ounces on a KeyMo mount, per Dead Air. It's 6.4 inches long with Xeno and 6.9 inches with KeyMo.
Xeno or KeyMo mount?
- Xeno is shorter and lighter. KeyMo is a quick detach mount that adds about half an inch and a couple of ounces but moves between rifles faster.
