A Silent Steel Safe Blank Firing Adapter (S-BFA) can withstand 2-4 accidentally fired live rounds, depending on the type of ammunition used.

The Safe Blank Firing Adapter (S-BFA) is equipped with a safety relief valve. This high-pressure safety valve is designed to protect the user and the weapon against overpressure caused by accidentally fired live rounds.

The back pressure can be adjusted to ensure reliable cycling with different types of blank ammunition and various barrel lengths. A yielding structure will absorb the energy of a live bullet, which will prevent damage to the barrel thread.
