Surefire Suppressor Blank Safety Device for M4 Carbine - SF-BSD-556-M4

The SureFire Blank Safety Device mimics the length, weight, and attachment system of a SOCOM556-RC suppressor for training with blanks on the M4 Carbine. A rotating wheel within the BSD moves an internal spud that seals against the muzzle of the weapon system for proper functioning with blanks. Additionally this product is designed to safely capture up to three live rounds in case live ammunition is mistakenly introduced within the training environment.

*BSD will be rendered inoperable if a live round is mistakenly fired.
