Bersa WhisperTech Suppressors: B22, B9, B556 and B762 Ship Now

Bersa USA is selling four suppressors right now: the B22, the B9, the B556, and the B762. All four are shipping, not being taken as deposits, and dealer pricing on every one of them sits meaningfully below Bersa's published list.

The line is branded WhisperTech, and Bersa's pitch is a design change rather than a materials change. The company describes a patented Couvillion method that separates solids out of suspension and lets the gas flow through the can, which it contrasts against the Maxim-style solid-gas suspension that has been the default since 1902. Bersa claims the result is minimal ballistic point-of-impact shift, reduced muzzle flip, and minimal breech blowback. Those are manufacturer claims, and nobody outside Bersa has published measurements yet.

Flow-through is a real category with real advantages, and the back-pressure argument matters more than most spec-sheet lines: a low-back-pressure can pushes less contaminated gas at the shooter's face on a semi-auto host. It also usually costs something in raw sound reduction. Where Bersa's implementation lands on that tradeoff is exactly the number nobody has independently measured.

Bersa USA is based in Cartersville, Georgia, and all four tubes in its product photography carry the model, caliber, serial, and that address as a roll mark. All four carry Bersa's limited lifetime warranty, and Bersa describes the line as tool-free and user-serviceable, with the modular cans reconfiguring by hand.

The B22 is the value entry and the most flexible rimfire can in the group. Bersa rates it for .22 LR, .22 Magnum, .17 HMR, .17 WSM, and 5.7x28, and it is full-auto rated with .22 LR. The full-auto rating covers .22 LR only, not the rest of that list. The 5.7x28 rating is what separates it from a pure rimfire can, and the hosts it reaches on 1/2x28 are the threaded S&W M&P 5.7 and the threaded PSA 5.7 Rock. A Ruger-57 needs Ruger's drop-in threaded-barrel kit first, an FN Five-seveN ships unthreaded and takes an aftermarket M10x1.0 barrel plus an M10x1-to-1/2x28 adapter, and a PS90 presents no exposed 1/2x28 at all.

It is modular. In the compact configuration it measures 3.41 inches and 4.5 oz; extended it runs 5.8 inches and 6.4 oz. Construction is 6AL-4V titanium and 17-4 stainless steel under a high-temperature Cerakote. Bersa claims roughly 42 dB of reduction in the full configuration, putting the host at approximately 114 dB. The mount is 1/2x28 direct thread. Bersa lists no HUB threads on the B22, the way it does on the B556 and B762.

At 4.5 oz compact, the B22 sits in the weight class that makes a Ruger Mark IV or a 10/22 pleasant instead of nose-heavy. Our best .22 LR suppressors guide ranks the field it is walking into, and the maintenance section there matters more here than the spec sheet does: rimfire cans lead up, and cleaning intervals are per-product rather than universal. Bersa has not published a service interval for the B22.

The B9 is the multi-caliber pistol and carbine can, and its caliber list is the reason to look at it. Bersa rates it for 9mm Luger, .22 LR, .300 Blackout subsonic, 350 Legend, .357 Magnum, and .38 Special. It also carries a conditional .300 Blackout supersonic rating that Bersa limits to hunting use, five shots at a time, followed by a cooldown. That restriction is a real constraint, not fine print: this is not a can for supersonic .300 Blackout range sessions.

It is modular like the B22. Compact is 5.8 inches and 9.2 oz, and the full-size configuration is 8 inches and 11.3 oz. Materials are Grade 9 titanium, 17-4 PH stainless steel, and 7075-T6 aluminum. A piston ships in the box for semi-auto pistol hosts, which is what makes the can usable on a tilting-barrel pistol instead of just on a fixed-barrel carbine. Bersa claims up to 32 dB of reduction in the full configuration.

Bersa does not publish a full-auto rating for the B9, which is worth flagging because some retailer listings describe it as full-auto rated. Until Bersa says so on its own product page, treat it as a semi-auto can. If you are pairing one with a pistol host, the booster and tilting-barrel mechanics in our pistol suppressor setup guide are what actually determine whether the gun cycles, and the 9mm suppressor rankings cover the cans it competes with on PCC and MP5 hosts.

The B556 is where the materials story gets interesting for the price. It is built from Inconel 718 and 17-4 stainless steel, the same nickel superalloy family that premium 5.56 cans use in the blast baffle, and Bersa specifies oversized baffles and an end cap rated to 6mm. That endcap rating is why the caliber list is wider than the model name suggests: 5.56 NATO, .223 Remington, 6mm ARC, .243 Winchester, 6mm PRC, and 6mm Creedmoor.

It measures 5.825 inches and 15.2 oz, and it is full-auto rated. Bersa claims 32 dB of reduction, or roughly 132 dB at the ear. The rear of the tube is HUB 1.375-24, and it ships with a 1/2x28 direct-thread mount installed, so the mount can be swapped for a KeyMo, ASR, or 3-lug adapter without buying a different can.

A 15.2 oz full-auto rated Inconel 5.56 can with HUB threads is competitive on paper against cans that list for considerably more. Our budget 5.56 suppressor guide covers the value bracket the B556 lands in, and the HUB suppressor guide explains why the 1.375-24 rear thread is the single spec that keeps a can useful across future hosts. HUB compatibility runs one direction only, so a can either left the factory with those threads or it did not.

The B762 is the flagship and the most versatile can in the line. Bersa rates it for nine cartridges: .300 Win Mag, .308 Winchester, 5.56 NATO, .223 Remington, 6mm ARC, 6.5 Creedmoor, .300 PRC, 6.5 PRC, and 7mm Magnum. That span, from a 5.56 carbine to a magnum bolt gun, is the entire pitch.

It runs 6.75 inches and 17.2 oz in Inconel 718 and 17-4 H900 stainless steel, and it is full-auto rated. Bersa publishes two sound figures rather than one, which is more honest than the usual single headline number: up to 30 dB of reduction on a 20-inch .308 Winchester rifle, roughly 138 dB at the ear, and 24 dB on .300 Win Mag out of a 26-inch bolt action. The mount is 5/8x24 direct thread with an integrated muzzle brake, and the rear is HUB 1.375-24.

The removable front end cap is the detail worth noting on a multi-caliber can. Endcaps are the part that gets damaged by a baffle strike or eroded by magnum gas, and a user-replaceable one turns what would otherwise be a factory return into a parts order. Our .30 caliber suppressor rankings cover the AR-10 and bolt-gun field it competes in, and the multi-caliber guide works through the tradeoff you accept when one can covers everything. If you are matching a can to a host you already own, the rifle builder filters suppressors against your barrel thread pitch instead of making you cross-check the caliber list by hand.

Three things are absent from all four product pages, and they are the three that separate a spec sheet from a track record. There is no independent suppression rating from PEW Science or any other third party, so every dB figure above is Bersa measuring its own product. There is no published minimum barrel length on any of the four, which matters most on the B556 and B762 if you are planning a short-barreled host. And there is no published firing schedule behind the full-auto ratings, so "full-auto rated" is a category claim rather than a specific round-count protocol.

None of that makes the cans bad. It makes them unproven, which is the normal condition for a suppressor line in its first year. The materials are real, the HUB threads are real, and the caliber ratings come from the manufacturer that warranties them. What you are trading at this price is the third-party data that a Dead Air or a HUXWRX has accumulated over years.

Bersa launched a different five-model WhisperTech line in January 2025: the B-22, the B-9X, the B-556X, the B-762P, and a 6.5mm B-65P that has no successor in the 2026 lineup. Those are still on dealer shelves alongside the new four, priced below them, and the naming is close enough to cause real confusion at checkout.

The 2026 models drop the letter suffixes. B22, B9, B556, B762. They carry higher list prices, different material specs, and in the case of the B556 and B762, HUB threads the older cans did not advertise. If a listing says B-556X or B-762P, it is the previous generation. Check the model designation and the SKU before you commit. Backing out after the paperwork is filed means the dealer withdrawing the application and starting a fresh transfer, which resets the wait.

The federal making and transfer tax on a suppressor has been zero since January 1, 2026, but that changed the tax, not the process. For most buyers the path is still a Form 4, fingerprints, a NICS check, and NFA registration through a dealer. Suppressors are legal to own in 42 states.

The one exception is narrow and party-specific. The August 2026 injunction in Silencer Shop Foundation v. ATF lets covered buyers take a suppressor home on a 4473 and NICS check alone, with no Form 4, but coverage is limited to the plaintiffs, members of the six plaintiff organizations, and customers of the plaintiff companies. Everyone outside that scope still files. Our suppressor purchase walkthrough covers both paths step by step, and the suppressor buying guide tracks current wait times, which now run days rather than months on the eForm pipeline.
