Best 30 Cal Suppressor: 7 Cans by Price and Decibels

Last updated: October 31, 2026

Short answer: No single .30 cal suppressor wins everything. In the independent tests we found, the Dead Air Nomad-L and Otter Creek Labs Hydrogen L posted the strongest numbers on bolt guns, the Omega 36M covers the most calibers, and the Banish 30 and Flow 762 Ti are the light ones. Prices run from $580.99 for the Gemtech Neutron to $1,299 for the Flow with its brake.

A .30 cal can is where most folks go when they want one suppressor for the deer rifle, the AR-10 and maybe a 300 Blackout too. It’s also where the claims get loudest. Every maker has a decibel number, and none of them were measured on the same rifle with the same ammo and the same microphone. So we lined up seven cans we list, took the specs from each maker’s own page and gathered the sound data run by someone other than the company selling the can. Every number below comes with its test, and we won’t average them or put numbers from two different tests side by side. That’s how a deer camp argument starts.

The seven cans and how we picked them

We stuck to .30 caliber and multi-caliber suppressors available to order on our site as of October 31, 2026, and picked across the price range: the Gemtech Neutron 7.62, the Griffin Optimus 7, the Dead Air Nomad-L, the Otter Creek Labs Hydrogen L Ti, the SilencerCo Omega 36M, the Banish 30 and the HUXWRX Flow 762 Ti. The Dead Air Sandman X gets its own section because folks keep asking how it stacks up against the Omega, and we tacked a short note on the Stealth Additive Works Tisha onto the end.

One thing before we start. You have to be 21 to buy a suppressor from a dealer, the same as a handgun (18 U.S.C. 922(b)(1)). The rest of the buying process has been changing, so rather than repeat it here, our guide to buying a suppressor walks through it as it stands today. If you’re shopping for a rimfire can too, our .22 suppressor comparison works the same way.

Price tiers, as of October 31, 2026

These are the prices on our product pages the day we wrote this. Prices move, so check the listing before you lean on any of this math.

Under $600. The Gemtech Neutron 7.62 is $580.99, a good bit below everything else here. It’s a steel and titanium can rated from 5.7×28 up to 300 Win Mag, and it uses the common HUB thread.

About $750 to $925. The Griffin Optimus 7 runs $759.95 with the UTI HUB mount, $864.45 with the Taper Mount and $921.45 with the Dual-Lok. The Dead Air Nomad-L is $889. Both are stainless cans, and both are on the heavy side.

About $950 to $1,000. The Otter Creek Labs Hydrogen L Ti is $950, the SilencerCo Omega 36M is $993.65 and the Banish 30 is $999. The Dead Air Sandman X runs $949 in FDE with a Xeno mount and $999 with KeyMo. Here’s where titanium and modular designs come in.

Over $1,000. The HUXWRX Flow 762 Ti is $1,299, and that listing includes a muzzle brake.

.30 cal suppressor comparison: the specs

Here’s how each maker lists them. Where a maker doesn’t publish a number, we left it out or used an independent lab’s measurement, and the source column says which. Otter Creek Labs’ current page wouldn’t load for us, so its numbers come from an archived copy.

Weight is the big spread. The Banish 30 short and the Omega 36M short both come in under 10 ounces, while the Nomad-L is 18.3 and the Optimus 7 runs 17.8 to 19.7 depending on the mount. Length runs from the Omega’s 4.9 inches to the Hydrogen L‘s 9. Four of the eight use the 1.375×24 HUB thread in some form, which matters if you want to swap mounts later.

The specs don’t all agree from one source to the next. The Neutron is listed at 14.6 ounces on Gemtech’s direct-thread page and 16.1 on another Gemtech page. HUXWRX lists the Flow 762 Ti at 6.7 inches, its white paper says it adds 6.1 inches to the barrel and PEW measured 6.75. Griffin’s Optimus 7 page lists 17-4 stainless in one spot and 718 Inconel in another. SilencerCo’s page says the Omega needs a 20-inch barrel on 300 Win Mag, while an older white paper says 18. We went with each maker’s current product page.

What the decibel numbers actually say

Maker claims don’t line up with each other. Griffin says the Optimus 7 knocks off 32.9 dB and reads 135.9 dB on a 16-inch Troy .308 with M118LR (Griffin). SilencerCo lists a 136.9 dB muzzle average on .308 for the Omega 36M (SilencerCo). Banish says 34.5 dB of reduction at the ear with .308 (Banish), and Otter Creek Labs claims 130 dB on a 16-inch .308 (OCL). Each is the maker’s own rifle, ammo and meter spot, and some are a reduction while others are a reading.

What you can trust is a single test that runs several cans on the same gun, the same ammo and the same microphone. Each row below comes from one of those, and you should only compare rows that share a source, host and test date.

PEW Science doesn’t publish plain decibels in its free reviews. It gives a Suppression Rating that weighs the shape of the sound, not just the peak, and higher is quieter. Four of our cans went through the same Savage .308 with the same Federal XM80. The Dead Air Nomad-L scored 52.0 and the Otter Creek Labs Hydrogen L Ti 49.8, with the HUXWRX Flow 762 Ti at 41.6 and the Gemtech Neutron 7.62 at 38.4 (Nomad-L, Hydrogen-L, Flow 762 Ti, Neutron). When PEW published the Nomad-L review in 2021, it called the Nomad-L and the CGS Hyperion the highest performing supersonic centerfire rifle silencers it had tested to that date.

The Thunder Beast Arms Silencer Summit is the other clean comparison. TBAC runs every entered can through the same rifles and the same microphones and publishes the whole table. TBAC makes suppressors too, but its numbers sit in the same table as everybody else’s. On the 2024 .308, the Hydrogen-L metered 132.7 dBA at the muzzle and 123.68 at the shooter’s ear, and the Flow 762 Ti came in at 144.1 and 133.40 (TBAC 2024 results).

The 2025 event gives us three of our cans on the same 300 Win Mag. At the shooter’s ear, the Hydrogen L read 125.17 dBA, the Banish 30 V2 long 131.90 and the Sandman X 138.13, against 157.13 with no can. On subsonic 300 Blackout, the order shifted. The Hydrogen L led again at 114.98 at the ear, but the Sandman X edged the Banish there, 125.41 to 126.06, even though the Banish was quieter at the muzzle (TBAC 2025 results). Where you stand changes the answer.

The Banish 30 has a wrinkle. TBAC’s 2024 table has a Banish 30 at full length, which looks to be the version before the V2, and PEW’s free Banish 30 review covers that original model too. The 2025 TBAC rows are the V2, which is what Banish sells today as the HNT 30 TI. We didn’t find any independent data for the Optimus 7, and the Neutron and Nomad-L have PEW numbers but no TBAC rows we could find.

Gemtech Neutron 7.62: the budget pick

At $580.99, the Gemtech Neutron 7.62 costs a few hundred dollars less than anything else here. Gemtech builds it from 17-4PH stainless and 6AL4V titanium, rates it from 5.7×28 to 300 Win Mag and lists it as full-auto rated (Gemtech). It’s 6.6 inches and 14.6 ounces without its adapter, with a 1.375-24 HUB attachment, so it’ll take a wide range of mounts.

Mind the barrel limits. Gemtech says 12 inches on .308, 16 on 6.5 Creedmoor and 300 Win Mag, and 7 on 5.56. Gemtech doesn’t publish a decibel number. PEW’s 38.4 on the Savage .308 is the lowest of the four PEW scores in our group (PEW Science).

Dead Air Nomad-L and Otter Creek Labs Hydrogen L: the quiet ones

If the goal is the quietest bolt gun you can build, these two posted the strongest independent numbers here. The Dead Air Nomad-L is 8.4 inches, 1.735 inches across and 18.3 ounces of fully welded 17-4 PH stainless. Dead Air rates it up to .300 Norma Mag, lists no barrel restrictions and ships it direct thread in 5/8-24, with KeyMo and Xeno compatibility if you’d rather run a muzzle device (Dead Air).

The Otter Creek Labs Hydrogen L Ti goes the other way on weight. Otter Creek Labs builds it tubeless from Grade 5 titanium, at 9 inches and 11.9 ounces without a mount, with 1.375×24 rear threads and a 5/8×24 direct-thread adapter in the box. It’s rated for limited full-auto use, and OCL posts barrel minimums by cartridge, from 11.5 inches on 5.56 up to 24 on 300 Norma Mag and 300 RUM (OCL).

On the PEW Savage .308, the Nomad-L scored 52.0 and the Hydrogen-L 49.8, the top two of our four. Among our cans, the Hydrogen L also posted the lowest numbers in both TBAC years. The tradeoff is size. They’re the two longest cans here, and the Nomad-L is the heaviest of the pair by more than 6 ounces. PEW’s Hydrogen-L review also publishes back pressure comparisons against other .30 cans, worth a read if you plan to run it on a gas gun (PEW Science).

Omega 36M vs Sandman X

This is the matchup we hear about most, and the honest answer is that we didn’t find one independent test that ran both cans. So we’ll give you each can’s own record and let you judge.

The SilencerCo Omega 36M is a modular can that runs 4.90 to 6.85 inches and 9.8 to 12.5 ounces, depending on whether the front section is on. SilencerCo rates it from 5.7×28 and 9mm up through 5.56 and .338 Lapua and calls both lengths full-auto rated. It mounts by ASR, direct thread, 3-lug or piston, and SilencerCo lists a 136.9 dB muzzle average on .308 (SilencerCo). Baffled.app, which indexes TBAC’s results, lists an Omega 36M long from the 2024 summit at 130.7 dBA at the shooter’s ear (Baffled). We couldn’t pull that row off TBAC’s own page, so it stays out of our table.

The Dead Air Sandman X is a fixed-length can, a little fatter than the Omega: 6.4 inches with Xeno or 6.9 with KeyMo, 1.65 inches across and 14.5 to 16.8 ounces of Haynes 282. Dead Air rates it to .300 RUM with no barrel restrictions and full-auto use (Dead Air). Its independent numbers come from TBAC’s 2025 tables, where it trailed the Hydrogen L and Banish 30 on 300 Win Mag and finished between them at the ear on subsonic 300 Blackout.

That video is from a suppressor maker, and it runs the older Sandman S, not the X. We’re including it because it’s a straight-up 30 cal shootout with the Omega 36M in it.

If you shoot a lot of different guns, the Omega’s caliber range and mount options are hard to beat. If you shoot a .30 cal gas gun, and Dead Air’s KeyMo devices are already on your rifles, the Sandman X is the one built around that setup.

Banish 30: the modular titanium can

The Banish 30 is the one in our lineup Banish now sells as the HNT 30 TI. It’s 100 percent titanium and user serviceable, and it runs either 6.4 inches and 9.5 ounces or 8.17 inches and 12.4 ounces with 11 baffles (Banish). Banish rates it from .17 HMR to .300 Weatherby, lists it as limited full-auto rated and takes both 1.375×24 HUB and 5/8×24 mounts. Our listing shows only the short-length spec, so lean on Banish’s page for the long numbers.

In TBAC’s 2025 .308 test, the V2 long metered 139.0 dBA at the muzzle and 129.45 at the ear. In the same event’s 300 Win Mag test it sat between the Hydrogen L and the Sandman X.

HUXWRX Flow 762 Ti and Griffin Optimus 7

The HUXWRX Flow 762 Ti is 3D-printed from Grade 5 titanium and weighs 11.8 ounces. HUXWRX builds it around its Flow-Through design, which it says cuts the toxic fumes that come back at the shooter, and it’s full-auto rated with no barrel restrictions (HUXWRX). It mounts on HUXWRX QD brakes and flash hiders, and our listing comes with a brake. The white paper rates it from 5.56 through 300 PRC and 30-06.

On sound, the Flow trails the Hydrogen-L in both PEW and TBAC 2024. PEW ran it head to head with a Dead Air Nomad-Ti on a .308 bolt gun and found similar Suppression Ratings, with the two cans behaving differently in how they get there (PEW Science). The Nomad-Ti isn’t the Nomad-L we list, so don’t read that as a tie with the Nomad-L.

The Griffin Optimus 7 is the heavy steel option. Griffin builds it from 17-4 H900 stainless at 1.73 inches across, and it ranges from 6.875 inches and 17.8 ounces with the UTI HUB mount to 7.56 inches and 19.5 ounces with the Taper Mount (Griffin). It’s full-auto rated, and the manual calls for at least 12.5 inches of barrel on .308 and 300 Win Mag. Griffin’s 32.9 dB reduction claim is the only sound number we found for it.

Titanium vs steel, and what weight does on a hunting rifle

The split in this group is clean. The Hydrogen L, Banish 30 and Flow 762 Ti are titanium. The Nomad-L and Optimus 7 are 17-4 stainless, the Neutron and Omega 36M mix stainless and titanium, and the Sandman X is Haynes 282. Weight follows the material. The three titanium cans run 9.5 to 12.4 ounces, and the two stainless cans run 17.8 to 19.7.

On a hunting rifle you carry all day, that’s roughly 5 to 10 ounces more hanging off the end of the barrel. On a range gun that lives on a bipod, it matters a lot less. Whatever the material, check the barrel limits in the spec table before you put any of these on a short magnum.

One can for everything, 5.56 included

If you want one suppressor for your .308, your AR-15 and your 300 Blackout, look at the caliber ratings first. The Omega 36M covers the most ground, from 5.7×28 and 9mm up to .338 Lapua. The Banish 30 goes from .17 HMR to .300 Weatherby, and the Neutron runs from 5.7×28 to 300 Win Mag. The Hydrogen L and Flow 762 Ti both list 5.56. Dead Air and Griffin rate their cans by the top cartridge, so check the manual before you run anything smaller.

Barrel minimums matter more here than anywhere. The Neutron allows 5.56 on a 7-inch barrel, the Omega on 10 inches and the Hydrogen L on 11.5.

HUB mounts and why they keep coming up

The 1.375×24 HUB thread is the closest thing to a common rear thread in this class. The Neutron, Hydrogen L, Banish 30, the Optimus 7 UTI and the Tisha all use it, so you can pick from a lot of mounts from a lot of makers. Dead Air uses KeyMo and Xeno, SilencerCo has its Charlie mounts and HUXWRX uses its own QD. If you’re not sure which setup fits your rifle, our suppressor mounts explainer covers direct thread, QD and HUB.

First round pop

First round pop is the louder first shot through a cold can, caused by the air sitting inside it. PEW Science says the first shot always sounds different from the ones that follow, and peak numbers alone don’t always show it. Its free reviews of the Nomad-L, Hydrogen-L and Flow 762 Ti each break out the first-round waveform (PEW on the Nomad-L). Dead Air claims minimal first-round pop for the Nomad-L. That’s a maker claim, and it’s the only one we found on any of these pages.

Also worth a look: SAW Tisha and PWS BDE 762

The SAW Tisha 7.62 Inconel is a different animal. It’s a 4.1-inch, 15-ounce K-can in 718 Inconel that adds 3.7 inches with the included direct-thread mount, takes 1.375×24 hubs and is rated for .30 cal rounds up to 300 RUM (Stealth Additive Works). SAW doesn’t rate it for barrels under 8 inches with an FRT or full-auto. It’s $1,179 on our site. We didn’t find independent sound data for it, and our Stealth Additive Works rundown covers the rest of the family.

The PWS BDE Ti 7.62 is $999.95, and PEW rated the BDE 762 at 48.7 in its long setup and 40.4 short on the same Savage .308 as the others (PEW Science).

Which one we’d put on which gun

For the quietest bolt-action .308 or 300 Win Mag, the Nomad-L and the Hydrogen L carry the strongest independent numbers, and the Hydrogen L does it at 6 ounces lighter. For a hunting rifle you carry, the Banish 30 and the Flow 762 Ti are the lightest full-size options, and the Banish has TBAC numbers for both .308 and 300 Win Mag. For one can across a whole safe, the Omega 36M has the widest rating. On a budget, the Neutron gets you a HUB-mount can for under $600.

You’ll find all of these and the rest of the lineup in our silencers section. If you’ve never bought a can before, start with our guide to buying a suppressor.

FAQ

What is the best .30 cal suppressor?

It depends on what you’ll shoot. On one .308 bolt rifle, PEW Science rated the Dead Air Nomad-L 52.0 and the Hydrogen-L 49.8, the top two in this group. In Thunder Beast Arms’ 2025 tests, the Hydrogen L beat two other cans on 300 Win Mag and subsonic 300 BLK. For one can across calibers, see the Omega 36M.

Can you shoot 5.56 through a .30 cal suppressor?

Often, yes, if the maker rates it. The Neutron, Hydrogen L, Omega 36M, Banish 30 and Flow 762 Ti all list 5.56, with barrel minimums from 7 inches on the Neutron to 11.5 on the Hydrogen L. Dead Air and Griffin list .30 caliber ratings by top cartridge, so check their manuals before you run a smaller round.

Is the Omega 36M or the Sandman X quieter?

We can’t give you a fair answer, because we didn’t find one independent test that ran both. SilencerCo lists a 136.9 dB muzzle average on .308 for the SilencerCo Omega 36M. Thunder Beast Arms tested the Sandman X on 300 Win Mag and subsonic 300 BLK in 2025, but the Omega wasn’t in those tables.

What is the lightest .30 cal suppressor here?

The Banish 30 in its short setup, at 9.5 ounces by Banish’s numbers, with the Omega 36M short at 9.8 ounces close behind. Running full length, the Flow 762 Ti is 11.8 ounces and the Hydrogen L is 11.9 without its mount. The heaviest is the Optimus 7 Dual-Lok at 19.7 ounces, per Griffin.

What is a HUB mount on a suppressor?

It’s a 1.375×24 thread on the back of the can that accepts mounts from many makers. The Neutron, Hydrogen L, Banish 30, Tisha and the Optimus 7 UTI use it here. Dead Air uses KeyMo and Xeno, SilencerCo uses its own Charlie mounts and HUXWRX uses its own QD. Our suppressor mounts explainer goes deeper.

What is first round pop?

It’s the louder first shot through a cold can, caused by the air sitting inside it. PEW Science notes the first shot always differs from the ones after it, and peak numbers don’t always show it. Dead Air claims the Nomad-L has minimal first-round pop. That’s a maker claim, so weigh it against PEW’s waveforms (PEW).
