Stealth Additive Works Suppressors: The Tisha .30 Inconel and the Rest of the Lineup

Last updated: October 30, 2026

Short answer: Stealth Additive Works (SAW) is a Twin Falls, Idaho company that 3D prints suppressors in titanium and 718 Inconel. Its best-known can is the 4.1-inch Tisha. The Tisha .30 Inconel is rated for .30 caliber up to 300 RUM and ships with a 5/8-24 direct thread mount on a 1.375×24 HUB thread. SAW also makes the Shiv, Ekron, Orev, Katan, Keren and Klik (SAW).

We just started carrying Stealth Additive Works, and the first thing folks ask about is the Tisha. Fair enough. It’s a 4.1-inch can that keeps showing up in the same conversation as cans twice its size. Below we’ll walk through the Tisha .30 Inconel (our listing calls it the Tisha 7.62), the rest of the SAW lineup, and how you actually get one of these on your rifle, which is where most of the real questions come from.

Who Stealth Additive Works is

SAW is a young company and doesn’t hide it. Its About page calls SAW “new to the suppressor market” and says it introduced two products within 90 days of building its first suppressor. Everything is 3D printed, mostly in Grade 5 (ELI) titanium, with 718 Inconel on the heavier-duty Tishas. The Tisha design is covered by a U.S. registered patent, number 12613072B12, with more pending, according to SAW’s Tisha .30 Inconel page.

Printing lets SAW build internal shapes you can’t machine out of a tube. That’s how a 4.1-inch can ends up on top of a PEW Science 5.56 report, which we’ll get to. We carry the full SAW line in our suppressor catalog.

The Tisha .30 Inconel (Tisha 7.62)

This is the headliner, and it’s easy to see why. The Tisha 7.62 Inconel in FDE (also in black) is 4.1 inches long and 15 ounces with no mount. SAW says it adds 3.7 inches to your barrel with the included 5/8-24 direct thread mount, assuming 0.7 inches of barrel thread. It’s rated for all .30 caliber firearms up to 300 RUM, with no barrel length restriction on subsonic ammo. Running full auto or a forced reset trigger? Then SAW says no barrel shorter than 8 inches (SAW).

SAW’s own claim is that the Inconel .30’s back pressure and sound “meet or exceed” the titanium 5.56 Tisha. That’s a big claim for a .30 cal can this short. SAW also says the Inconel Tisha is outlasting muzzle devices in its hard use testing.

Inconel or titanium

SAW also makes the titanium Tisha 7.62. It’s the same 4.1 inches but only 10.5 ounces. It’s rated for 300 PRC and below, and it ships with a Plan B hub and a Plan B muzzle brake in 5/8-24 instead of a direct thread mount. SAW is upfront that the titanium .30 is 2.8 dB louder than the titanium 5.56 Tisha (SAW).

So here’s how we’d call it. If the can’s going on an AK or a 300 Blackout that’ll see real round counts, we’d take the Inconel. It’s rated for bigger cartridges, and SAW puts its sound and back pressure ahead of the titanium .30. If ounces matter more, like on a light hunting rifle you carry all day, the titanium makes sense. Four and a half extra ounces won’t hurt your shoulder. On the end of a short barrel, though, your support hand will notice.

On a 300 Blackout or an AK

SAW’s page says the Inconel .30 is “perfect for your AK, or 300 Blackout AR.” A lot of 300 Blackout barrels are threaded 5/8-24, which lines right up with the mount in the box. Check yours before you order anything, though. If you’re still working out ammo, barrel length and how loud subs really are, our post on running 300 Blackout suppressed covers that side.

AKs take a little more thought. Most are threaded 14×1 left hand, so the included 5/8-24 mount won’t go on as-is. You’ve got a couple of ways around that, and we cover them in the mounts section below.

How quiet is it, really

Here’s what independent testing says, and what it doesn’t. PEW Science tested the titanium Tisha 5.56 on a 10.3-inch MK18 with Federal XM193 and a direct thread mount. It scored a composite Suppression Rating of 49.6. In its December 22, 2025 report, PEW said the Tisha “outperforms all 5.56 suppression systems evaluated by the PEW Science Laboratory, as of the date of this report publication.” PEW also said it had the highest shooter’s ear rating on a reciprocating 5.56 in its rankings to that point.

That test is the titanium 5.56 Tisha only. We haven’t seen PEW, or anybody else, run the Tisha .30 through the same protocol. So we’re not going to hand you a number for it. What we have is SAW’s word that the Inconel .30 meets or beats the titanium 5.56. PEW also notes the name comes from the Russian word for “quieter.” That’s a bold thing to name a suppressor, a little like naming a bird dog Points Real Good. On the 5.56 at least, it backed it up.

The other Tishas

The titanium Tisha 5.56/6mm is the PEW-tested can. It’s 10.5 ounces, rated for 5.56 and all 6mm and below, and ships with a Plan B hub and a 2-port 1/2-28 brake. SAW lists a 10.3-inch minimum barrel. For anything faster than one round a second, SAW requires an approved muzzle device, meaning the included brake or something like an ASR (SAW). The Inconel Tisha 5.56/6mm is 15 ounces and ships with a 1/2-28 direct thread mount. SAW says it meets or exceeds the titanium version on sound and back pressure (SAW).

The Tisha 9mm is built for pistol-caliber carbines. It’s full auto rated for 9mm and mounts by 1/2-28 direct thread. SAW also rates it up to 300 PRC from a 22-inch barrel, but wants a multi-port muzzle brake for full auto or FRT use on rifles (SAW).

The rest of the SAW lineup

Here’s every SAW model we list, side by side. The links in the last column go to our listings.

Specs from Stealth Additive Works’ product pages (SAW shop), checked October 29, 2026. The Tisha 9mm length comes from our listing, since SAW’s page doesn’t give one.

Ekron

The Ekron is SAW’s longer titanium rifle can, built around low back pressure for gas guns. The Ekron 5.56 is 5.9 inches and 9 ounces. The Ekron 7.62 is 6.375 inches and 9.9 ounces, made for .308/7.62 NATO and smaller. Both are full auto rated only with a multi-port brake on barrels 10.3 inches or longer, and SAW says neither one is full auto rated on a direct thread mount. On barrels 14.5 inches and shorter, SAW recommends a multi-port brake and HUB adapter either way (Ekron 5.56, Ekron .30).

Orev

The Orev is the precision rifle can of the bunch. The Orev 7.62 is 6.1 inches and 7.5 ounces with its direct thread mount, rated up to .300 PRC. It has swappable end caps, and SAW says going to the 6mm cap gains 2.0 dB. The Orev 8.6 is set up for 8.6 Blackout and .338 ARC, rated up to .338 Norma Mag with a 22-inch minimum on magnums. The Orev’s front end is HUB threaded to take the SAW suppressor brake, which is sold separately. SAW says the brake and can together weigh 8.5 ounces (Orev .30, Orev 8.6, SAW brake).

Shiv

The Shiv is a 2.5-ounce, 3.7-inch 9mm can with no booster. SAW says that’s on purpose. They balanced the weight and where it sits to keep most semi-auto pistols cycling. SAW also warns that the Glock 17 and 34 are touchy with any suppressor and may need a lighter mainspring. It’s rated for 9mm, .38 Special, .357 Magnum, 300 Blackout subsonic and 5.7×28, and it’s full auto rated for 9mm (SAW). We list the Shiv in 1/2×28 and a 13.5×1 left-hand version.

The .22s: Katan, Keren and Klik

The Katan is the bigger of SAW’s two everyday rimfire cans. It’s 4.9 inches, 3.5 ounces and an inch across, with a patent-pending lead trap meant to keep gunk from caking up. SAW also rates it for 5.7×28 and for 5.56 on a barrel 16 inches or longer, at a slow rate of fire (SAW).

The Keren is the newer one. It’s 3.7 inches and 2.5 to 2.8 ounces. SAW says its own testing on a Taurus TX-22 pistol showed the Keren 4 to 6 dB quieter at the muzzle than the Katan (SAW). If we were picking a rimfire can from SAW today, that’s where we’d start.

Then there’s the Klik. At 1.5 ounces and 2.25 inches, it’s closer to a muzzle device than a can, and SAW says as much. It’s for .22 LR, .22 WMR and .17 HMR on 1/2-28 threads only. SAW is honest that it isn’t hearing safe on a typical pistol, and says it shines on barrels over 10 inches (SAW).

Getting a SAW can on your gun

If you’re new to mounts, start with our suppressor mounts explained post. It covers direct thread versus QD versus HUB. This section is the SAW-specific part.

Every Tisha has a 1.375×24 HUB thread on the back end. What comes in the box depends on the model. The Inconel Tishas ship with a direct thread mount, 5/8-24 on the .30 and 1/2-28 on the 5.56. The titanium rifle Tishas ship with a Plan B hub and a brake. Since HUB is a common standard, you can swap in a different mount if the one in the box doesn’t fit your setup. SAW does put a limit on that. The Tisha .30 Inconel “will fit muzzle devices protruding 1.5 [inches] or less from the back of the suppressor” (SAW). Measure before you buy, and ask the mount maker if you’re not sure.

HUB direct thread mounts

This is the simplest way to go. A HUB direct thread mount screws onto your barrel threads and gives the can a HUB thread to sit on. We carry them in the common pitches, like the Dead Air HUB direct thread mount in 1/2×28 and YHM’s in 5/8×24, plus more in our suppressor parts and mounts.

Recessed direct thread HUB adapters

This is the one people don’t know about until somebody shows them. The Wolfpack Recessed Direct Thread HUB Adapter seats down over your barrel instead of stacking out in front of it. Wolfpack says that cuts overall length by half an inch with the can on. Wolfpack designed it for rifles with a 1.25-inch difference between barrel and handguard length, so the adapter tucks in under the rail. It’s 17-4 stainless, 1.5 inches across, and needs 0.95 inches of clearance to the can’s first baffle. You install it with a 1.5-inch spanner wrench (Wolfpack Armory). We list it in 1/2×28.

Plan B HUB adapters

Here a Plan B-style muzzle device stays on the barrel, and a HUB adapter slips over it for the can to thread onto. Take the can off and you’ve still got a flash hider or brake out there doing its job. We carry the Wolfpack Low Profile Plan B HUB Adapter, the Ventilator (Wolfpack’s back pressure reduction adapter), and Wolfpack’s Night Howler Plan B flash hiders in 1/2×28 and 5/8×24.

On an AK

Two common routes. Use a YHM HUB direct thread mount in M14x1 LH so the Tisha threads straight on, or put a Kaw Valley 14×1 LH to 5/8×24 thread adapter on the barrel so the Tisha’s included 5/8-24 mount has something to grab. Either way, you’re stacking parts, so check the total against SAW’s 1.5-inch rule and get the alignment right before you send a round.

Leave the KeyMo at home

SAW is blunt about this one. Its warranty page says “Do not use the KeyMo QD mounting system. It is not secure,” and that KeyMo caused “the vast majority of damaged SAW suppressors.” Damage from a KeyMo mount isn’t covered. We’ll take their word on that.

SAW’s warranty

SAW backs its cans with a lifetime, no-fault warranty that’s fully transferable. It doesn’t matter how the damage happened or where you bought the can, and you don’t need to register it or show a receipt. It doesn’t cover loss or theft, misuse, cosmetic damage, unauthorized modifications or KeyMo damage. You’re also on the hook for shipping and dealer transfer costs. Read the whole thing on SAW’s warranty page before you need it.

How buying a SAW suppressor works now

The paperwork got a whole lot shorter this year. Per the ATF Open Letter, as of October 9, 2026, ATF no longer requires a Form 4, a tax stamp or federal registration to buy a suppressor. You buy it from a dealer in your own state on a Form 4473, same as a rifle. Your state’s law still applies, and some states still ban suppressors outright.

Our guide on how to buy a suppressor now walks through the whole process, including which states we can’t ship to and what happens to a Form 4 that’s still pending. You can also check our state shipping restrictions and how FFL transfers work with us.

This is general information, not legal advice. Check your state and local law, or ask an attorney.

If you buy cans and gear from us more than once in a blue moon, take a look at our Armory Club. Members see their member price on the product page and in the cart, and it’s never more than the regular price.

FAQ

Who makes the Tisha suppressor?

Stealth Additive Works, a suppressor maker in Twin Falls, Idaho. SAW 3D prints its cans in titanium or 718 Inconel, and the Tisha comes in 5.56/6mm, .30 caliber and 9mm versions. PEW Science says the name comes from a Russian word that means “quieter,” which is a lot to live up to (SAW, PEW Science).

Should I get the Tisha 30 in Inconel or titanium?

For an AK or a 300 Blackout that sees a lot of rounds, we’d lean Inconel. SAW rates the Inconel Tisha .30 to 300 RUM and says it meets or beats the titanium 5.56 Tisha on sound and back pressure. The titanium .30 is lighter at 10.5 ounces against 15, but SAW says it’s 2.8 dB louder than the titanium 5.56 (Inconel, titanium).

Will the Tisha 30 work on an AK or a 300 Blackout?

SAW pitches the Inconel Tisha .30 for exactly those two guns, with no barrel length limit on subsonic ammo. It ships with a 5/8-24 direct thread mount. Most AKs are threaded 14×1 left hand, so you’ll need a 14×1 LH HUB mount or a thread adapter. Check your barrel and SAW’s fit rules first (SAW).

How quiet is the Tisha?

PEW Science tested the titanium Tisha 5.56 on a 10.3-inch MK18 and gave it a composite Suppression Rating of 49.6. In its December 22, 2025 report, PEW said it outperformed every 5.56 suppression system it had evaluated to that date. That test covers the titanium 5.56 only. We haven’t seen the same test run on the Tisha .30 (PEW Science).

Can I use a different mount on a SAW suppressor?

Usually, yes. Tishas take a standard 1.375×24 HUB thread, so HUB direct thread mounts, Plan B HUB adapters and recessed HUB adapters are all on the table. SAW says the Tisha .30 Inconel fits devices sticking out 1.5 inches or less from the back of the can. The one thing SAW flat tells you not to use is KeyMo (SAW, SAW warranty).

What is Stealth Additive Works’ warranty?

SAW calls it a lifetime, no-fault, fully transferable warranty, and it doesn’t care where you bought the can or need a registration. It won’t cover loss or theft, misuse, cosmetic damage, unauthorized changes, damage from a KeyMo mount, or shipping and transfer costs. Read SAW’s warranty page for the full terms (SAW warranty).

Do I still need a Form 4 to buy a SAW suppressor?

Not anymore. ATF’s Open Letter says that as of October 9, 2026, a suppressor no longer needs a Form 4, a tax stamp or federal registration. You buy it from a dealer in your own state on a Form 4473. State law still applies, and some states still ban suppressors, so check before you order (ATF Open Letter).
