QDB Micro Flow Streamer | Silent Steel

The Silent Steel QDB Micro Flow Streamer is a compact modular rifle suppressor equipped with Silent Steel’s Boltlok™ Quick-Attach System (QDB). Designed for users who want to keep their rifle as short and lightweight as possible, the Micro Streamer significantly reduces muzzle signature while directing sound forward rather than to the sides. Its flow-through design reduces back pressure, minimizes harmful gas exposure to the shooter, and prevents increased weapon fouling. The Micro Streamer features a modular and multi-caliber construction. The suppression unit can be removed and replaced, allowing the suppressor caliber to be changed when required. The Micro Streamer is available with either an Aluminum or Stainless Steel body. The Stainless Steel body is full-auto rated. The Aluminum body is recommended only for 9.00 mm PCC carbines and single-shot rifles. The Boltlok™ Quick-Attach System (QDB) provides a lightweight, secure and stable mounting solution. The QDB mount adds only 20 g to the suppressor.

Upgrade Your Suppressor with a Silent Steel FlowComp Muzzle Brake
You can purchase the FlowComp separately, and we can even install it on your suppressor before shipping!

How to order:

• Add your Silent Steel suppressor to the shopping cart.
• Add the Silent Steel FlowComp Suppressor Muzzle Brake to the same order. Select the correct caliber – the FlowComp Muzzle Brake caliber must match your suppressor's caliber.
