Identical to our FA556-212 sound suppressor except FA556SA adapters are compatible with M100 GREM or SIMON rifle grenades when the suppressor is removed. The FA556SA suppressor adds just 4.6 inches to the original length of your AR-15, M4, M16, C8 SFW, or other rifle, yet it provides superior sound suppression—even firearms with 10.5" barrels using standard M855 ammunition have their average maximum sound pressure level reduced to well below the OSHA 140-decibel safe level.

All SureFire sound suppressors require an adapter for attachment to a firearm. Adapters for the FA556SA sound suppressor screw directly onto the original rifle muzzle threads—see Parts and Accessories below. Adapters for this suppressor vary in compatibility with US military bayonet, blank firing attachment, and M203 grenade launcher—verify before ordering if this is a concern.

Chosen by the US military, SWAT teams, and law enforcement agencies across the country, proven in the world's toughest combat conditions, only SureFire sound suppressors for rifles and machine guns combine every important suppressor feature: excellent sound, flash, and dust signature reduction—key components of SureFire's Total Signature Reduction™ (TSR); minimal and consistent zero shift regardless of attach/detach cycles; rock-solid attachment in seconds; compact size; minimal weight; fail-safe baffles to prevent bullet side-exit; and extreme durability permitting full-time use—in fact, your SureFire suppressor should outlast your firearm barrel.

All SureFire Fast-Attach® sound suppressors provide crucial tactical benefits—they protect shooter and team members against both permanent and temporary hearing loss, enhancing situational awareness and communication; reduce sound signature, concealing shooter's position; reduce or virtually eliminate muzzle flash and dust signatures, concealing shooter's position, preserving night vision and unobstructed view; reduce recoil, improving bullet impact observation and allowing faster follow-up shots.
