The SureFire SF-BSD-556 Blank Safety Device, for rifles and carbines chambered in .223 caliber (5.56 X 45 mm), allow for realistic training using blank ammunition. This BSD closely duplicates the weight, length, and feel of it’s equivalent SureFire sound suppressor. This product is designed to safely contain up to three inadvertently fired rounds of M855 ammunition without injuring the shooter or others. The Fast-Attach® mechanism allows for secure attachment or removal of the SF-BSD-556 to compatible SureFire adapters, no tools required.
NOTE: Blank Firing Adapter will only function properly when mounted on a SureFire Suppressor Adapter.
