Bersa B556 Inconel/Stainless 5.56-6mm Suppressor

Bersa B556 Inconel/Stainless 5.56-6mm Suppressor

Cover your 5.56 rifle and your 6mm rifles with one suppressor: the Bersa B556. It is a mission-focused, full-auto-rated can built from Inconel 718 and 17-4 stainless steel with a High Temperature Cerakote finish. Oversized baffles and a serviceable front end cap rated to 6mm let it handle far more than a standard 5.56 suppressor, and Bersa lists up to 32 dB of sound reduction.

The B556 is rated for 5.56 NATO, .223 Rem, 6mm ARC, .243 Win, 6mm PRC, and 6mm Creedmoor, so a shooter with an AR and a 6mm bolt gun can run a single suppressor on both. Bersa lists no barrel length limit. Inconel and stainless construction is made to handle the heat and pressure of sustained and full-auto fire, and the black Cerakote finish is rated for high temperatures. It weighs 15.2 ounces and is 5.825 inches long.

It ships with a 1/2x28 direct thread mount, and it is also compatible with the industry-standard 1.375x24 HUB mounting system, so it fits a wide range of host platforms. The front end cap is removable, which makes field maintenance easy, and you can replace it after damage without sending the whole suppressor back. The B556 carries Bersa USA's Limited Lifetime Warranty.

It is a good fit for AR-15 range days, 6mm precision rifles, hunting, and hard use. Suppressors can be transferred with a standard firearm background approval (Form 4473).
