Silent Steel Safe-Guard

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 mirage effects. By creating an air gap between the suppressor and the shield, heat transfer is minimized. The design facilitates airflow for cooling during shooting, ensuring the suppressor and shield remain at safe temperatures. According to the manufacturer, the Safe-Guard is highly durable and can withstand extreme temperatures, making it a reliable accessory for users seeking enhanced 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 gear against burns and it is a thermal insulator and signature reduction device that mitigates negative visible mirage effects.

The air gap between the carbon fiber outer hull and the suppressor will prevent heat from transferring from the suppressor to the heat shield. When shooting, the gun blast pressure will suck air from the venting holes at the back of the cover. The design allows high volumes of cooling airflow across the can which will cool down the suppressor and heat shield. Low thermal transfer materials will not get so hot that the Safe-Guard would burn gear or melt gloves when detaching the hot suppressor from the barrel.

The Safe-Guard is very light but still impact and heat resistant, capable of withstanding suppressor temperatures exceeding 600°C for short periods of time.

    Still a bit heavy and not sure why it can't have ventilation holes.
    I'm sure i can make a suppressor guard out of chicken wire that's not just 90% lighter but also 99% cheaper.

      @mig1nc I think you missed the point of the device. It's a heat shield that prevents mirage.

    So, same as Mod-Tac but you can only use it with their proprietary suppressors?
