Silent steel protection

THE Silent steel (Finland) Safe-Guard is a new heat shield designed for their Silent Steel Streamer series of suppressors. It acts as a protective barrier against burns and serves as a thermal insulator, reducing visible candling effects. By creating an air gap between the suppressor and the shield, heat transfer is minimized. The design facilitates airflow for cooling while firing, ensuring the suppressor and shield remain at safe temperatures. According to the manufacturer, the Safe-Guard is very durable and can withstand extreme temperatures, making it a reliable accessory for users looking for improved safety and performance.

Here is the news in full:

Silent Steel Safe-Guard is a heat shield for the Silent Steel Streamer family of suppressors.

The heat shield will protect the user and equipment from burns and is a thermal insulator and signature reduction device that mitigates negative visible candling effects.

The air gap between the carbon fiber outer shell and the suppressor will prevent heat from transferring from the suppressor to the heat shield. When firing, the pressure of the gun’s blast draws air from the vent holes in the back of the cover. The design allows for high cooling airflow through the box, which will cool the suppressor and heat shield. Low heat transfer materials will not get so hot that the Safe-Guard burns equipment or melts gloves when detaching the hot suppressor from the barrel.

Safe-Guard is very lightweight yet shock and heat resistant, capable of withstanding suppression temperatures in excess of 600°C for short periods.
