Bersa B-Series Suppressors: Models, Host Fit, and Buyer Checks
September 16, 2026
Bersa B-Series suppressors are a four-model family for rimfire, pistol, and rifle hosts. Announced in late August, the lineup includes the modular B22 and B9 plus the rifle-focused B556 and B762. The main research task is not simply choosing a caliber. Buyers should confirm the exact model generation, host threads, mounting system, ammunition rating, size, weight, and local transfer requirements before comparing listings.
The naming deserves special attention. Older search results may show Bersa WhisperTech models such as the B-9X or B-762P. Those names and specifications should not be treated as interchangeable with the newer B-Series lineup. A listing photo, model marking, included mount, and manufacturer stock number can help separate the products.
The short answer: choose the B22 for compatible rimfire use, the B9 for supported pistol and selected subsonic-capable hosts, the B556 for listed small-bore rifle cartridges, and the B762 when broader centerfire rifle coverage is the priority.
Bersa B-Series Suppressors at a Glance

|---|---|---|---|---|---|
| B22 | Modular rimfire | .22 LR, .22 WMR, .17 HMR, 5.7×28 | 3.41 in. / 4.5 oz compact; 5.8 in. / 6.4 oz full | Verify current package | $500 |
| B9 | Modular pistol | 9mm, .22 LR, .300 BLK, .350 Legend, .357 Mag., .38 Spl. | 5.8 in. / 9.2 oz compact; 8 in. / 11.3 oz full | 1/2×28 piston | $695 |
| B556 | Rifle | 5.56 NATO, .223 Rem., 6mm ARC, .243 Win., 6mm PRC, 6mm Creedmoor | Confirm current specification sheet | HUB compatible; 1/2×28 direct thread | $820 |
| B762 | Rifle | Nine listed calibers from 5.56 NATO through .300 Win. Mag. | Confirm current specification sheet | HUB compatible; 5/8×24 direct thread with brake | $900 |
These are launch specifications and suggested prices, not promises about every dealer package. Bersa describes all four as user-serviceable and finished in high-temperature Cerakote. Materials vary by model and include titanium, Inconel 718, and 17-4 stainless steel. Check the current manual and the exact item in front of you before relying on a summarized table.
How the B22 and B9 Modular Designs Differ
The B22 changes length without tools, giving a researcher a compact 3.41-inch setup or a 5.8-inch full configuration. The shorter form saves 1.9 ounces and reduces overall length. The longer form is the logical starting point when maximum suppression matters more than compact handling. Its published ratings extend beyond .22 LR to .22 WMR, .17 HMR, and 5.7×28, but every host and ammunition combination still needs to match the current manufacturer rating.
The B9 follows the same compact-versus-full-size idea at a larger scale. Its published lengths are 5.8 and 8 inches, with weights of 9.2 and 11.3 ounces. Bersa lists up to 32 dB of reduction, but decibel claims are test-dependent. Barrel length, ammunition, action type, measurement position, and environmental conditions can all change a recorded result. Treat the number as a manufacturer claim, not a cross-brand ranking.
A 1/2×28 piston is included with the B9 for compatible semi-automatic pistols. That detail does not establish fit by itself. Verify barrel thread pitch, shoulder geometry, piston compatibility, bore clearance, and whether the host requires a different fixed-barrel accessory. Readers comparing potential pistol hosts can browse semi-auto pistols, then confirm every interface with the firearm and suppressor makers.
B556 vs B762: Choosing Rifle Caliber Coverage
The B556 is the more focused rifle model. It uses Inconel 718 and 17-4 stainless steel, carries a full-auto rating, and has a serviceable front end cap with clearance for listed 6mm cartridges. Bersa lists 32 dB of sound reduction. Its HUB-compatible rear interface and included 1/2×28 direct-thread mount give buyers two mounting details to verify rather than assume.
The B762 expands the published range through .300 Win. Mag. and lists up to 30 dB of reduction. It arrives with a 5/8×24 direct-thread mount incorporating a muzzle brake. Its broader bore can make sense for a researcher who wants one suppressor across several compatible rifles. The tradeoff is that a broader-caliber model is not automatically the best performer on every smaller cartridge.
For either rifle model, start with the host rather than the marketing category. Check the barrel’s chambering, thread specification, minimum barrel length if one is stated, firing schedule, and concentric alignment. Review candidate semi-auto rifles separately from bolt-action hosts because gas behavior, mounting priorities, and firing pace differ.
Why Older Bersa Suppressor Names Can Cause Confusion
A search for a Bersa suppressor may also return the earlier WhisperTech B-22, B-9X, B-556X, B-65P, or B-762P. Those products were described with different construction, prices, dimensions, and internal designs. Similar caliber labels do not make an older B-762P the same product as a new B762.
This matters most in used listings and dealer inventory that reuses old copy. Compare the engraving and packaging against current Bersa documentation. Ask for the exact SKU and a clear photo of the rear mounting interface. Confirm which adapters, pistons, end caps, and tools are included. Research the Bersa brand catalog for related products, but use the suppressor’s own manual as the final compatibility reference.
Bersa B-Series Suppressors Research Checklist
- Record the exact model name, serial-marking format, SKU, and whether it belongs to the new B-Series or older WhisperTech family.
- Match every proposed cartridge and barrel length to the latest manufacturer rating.
- Confirm muzzle threads, shoulder geometry, bore clearance, and the correct piston or fixed-barrel mounting parts.
- List the included mount, end cap, tools, and any extra adapters needed for the intended host.
- Compare full system length and weight, including the mount, rather than comparing suppressor bodies alone.
- Read the cleaning interval and material restrictions. Rimfire ammunition can leave substantial fouling.
- Confirm warranty terms, dealer support, and replacement-part availability.
- Check current federal, state, and local requirements with a qualified dealer or agency before starting a transfer.
Federal and local rules can change, and they can differ by location. This article is product research, not legal advice. The announced lineup and launch specifications are summarized in the Bersa B-Series release. A dealer handling regulated items can explain the current process that applies to a particular buyer.
Who Each B-Series Model Fits Best
The B22 fits researchers centered on rimfire hosts who value low weight and two usable lengths. The B9 fits users comparing compatible 9mm pistols, pistol-caliber hosts, and a limited set of additional listed cartridges. In both cases, modularity creates a real choice between compact handling and the longer configuration.
The B556 is the focused option for compatible 5.56, .223, and listed 6mm rifle hosts. The B762 is the broader choice for a collection that spans small-bore rifles through supported .30-caliber magnum use. Neither answer is universal. A single known host may favor the more focused model, while several confirmed hosts may make wider coverage more useful.
The strongest buying decision comes from a written host list, not a vague plan to use the suppressor on everything. Record each firearm, cartridge, thread, barrel length, action type, and intended firing pace. Then compare only the models explicitly rated for every planned combination. That small worksheet can prevent an expensive case of alphabet soup.
