Oversized baffles and a serviceable front end cap rated to 6mm expand the B556‘s caliber compatibility well beyond standard 5.56 suppressors, covering 5.56 NATO, .223 Rem, 6mm ARC, .243 Win, 6mm PRC, and 6mm Creedmoor in a single can. Sound reduction performance reaches 32 dB, achieving approximately 132 dB SPL; reliably below the threshold for hearing-safe shooting.

The B556 ships with a 1/2×28 direct thread mount and is compatible with the industry-standard 1.375-24 HUB mounting system, giving shooters broad flexibility across a wide range of host platforms. The removable front end cap allows for easy field maintenance and can be replaced in the event of damage without returning the entire suppressor. Backed by a Bersa USA Limited Lifetime Warranty.
