Our .223 Hollywood blank-firing adapters (BFA) is the go-to adapter when using our .223 Hollywood blank ammunition. Each adapter is designed specifically for the firearm platform and the powder charge of the blank intended for use. There is no such thing as "one size fits all" and our BFA's might not work with another company's blank ammunition. These adapters are required to fit into the barrel. The torque of the flash suppressor will hold it into place when installed correctly. Lifespan depends solely on quantity of blank fired, adherence to general firearm maintenance procedures, and observation practices.
