What Is the Bersa WhisperTech Suppressor Line
Bersa USA sells four suppressors under its WhisperTech name: the B22, B9, B556, and B762. Bersa says the line uses the patented Couvillion method, which removes solids from suspension while gas flows through the device.
Bersa lists this design as smaller, lighter, and more accurate than traditional Maxim-method suppressors, with minimal point-of-impact shift and blowback. Bersa also lists user-serviceability as a key feature, and each model carries a Limited Lifetime Warranty from Bersa USA. The Bersa brand page covers the company’s pistols and rifles.
Bersa B22: Rimfire Suppressor
The B22 is a modular rimfire suppressor built from 6AL-4V titanium and 17-4 stainless steel. It mounts directly on 1/2x28 threads, and a replaceable thread adapter system fits other muzzle threads without tools.
Without tools, you can set it to a compact length of 3.41 inches and 4.5 ounces, or a full length of 5.8 inches and 6.4 ounces. Bersa lists about 42 dB of reduction in the full configuration. It is rated for .17 HMR, .22 WMR, 5.7x28, and full-auto fire with .22 LR.
Bersa B9: Pistol Suppressor With Piston
The B9 is a modular suppressor made from Grade 9 titanium, 17-4 PH stainless steel, and 7075-T6 aluminum. A 1/2x28 piston is included, which Bersa says allows reliable semi-automatic operation on most locked-breech pistols.
It is rated for 9mm Luger, .22 LR, .300 BLK subsonic, 350 Legend, .357 Mag, and .38 Special. Bersa also lists .300 BLK supersonic for hunting use only, with five shots and then a cooling period. Compact length is 5.8 inches and 9.2 ounces. Full length is 8 inches and 11.3 ounces, with up to 32 dB of reduction listed.
Bersa B556: Full-Auto Rated 5.56 and 6mm
The B556 is built entirely from Inconel 718 and 17-4 stainless steel. Bersa rates it for full-auto fire and lists oversized baffles and a front end cap rated to 6mm.
Listed calibers are 5.56 NATO, .223 Rem, 6mm ARC, .243 Win, 6mm PRC, and 6mm Creedmoor. It ships with a 1/2x28 direct thread mount, weighs 15.2 ounces, and measures 5.825 inches. Bersa lists 32 dB of reduction and compatibility with the 1.375-24 HUB mounting system.
Bersa B762: Large-Caliber Rifle Suppressor
The B762 uses Inconel 718 and 17-4 H900 stainless steel and is rated for full-auto fire. Bersa lists nine calibers, from .223 Rem and 5.56 NATO up to .300 Win Mag and 7mm Mag. Others include .308 Win, 6 ARC, 6.5 Creedmoor, .300 PRC, and 6.5 PRC.
It ships with a 5/8x24 direct thread mount with an integrated muzzle brake. It weighs 17.2 ounces, measures 6.75 inches, and is HUB compatible. Bersa lists 30 dB of reduction on a 20-inch rifle with M80 ammunition, and 24 dB on .300 Win Mag from a 26-inch bolt action.
How to Choose a Bersa Suppressor
Start with caliber, then check your muzzle thread. The B22, B9, and B556 use 1/2x28 threads, and the B762 uses 5/8x24. A rimfire host points to the B22, and a pistol points to the B9.
For rifles, the B556 covers 5.56 and 6mm cartridges at 15.2 ounces. The B762 covers larger cartridges up to .300 Win Mag at 17.2 ounces. Both mount to the 1.375-24 HUB system. Check each product page for the exact mount and caliber listed.
