The Silent Steel USA Raider Defense Micro Streamer 9mm (brand part no. MSTR-9MM-BLK-HUB-1_3/8) is a compact 9mm suppressor built on Silent Steel USA’s modular HUB mounting system, finished in a durable Armor Black coating. The Micro Streamer is the shortest suppressor in the Streamer lineup, giving 9mm pistol and PCC shooters meaningful sound reduction without the added length of the full-size Streamer or Compact Streamer models. Its 1.375×24 HUB thread accepts Silent Steel USA’s full range of direct-thread and quick-detach mounts, so the same can can move between multiple threaded hosts. Among our silencers and suppressed firearms, the Micro Streamer suits 9mm shooters who want the shortest possible suppressed footprint for a pistol-caliber build.
