QDB Compact Flow Streamer | Silent Steel

The Silent Steel QDB Compact Flow Streamer is a medium-size modular rifle suppressor equipped with Silent Steel’s Boltlok™ Quick-Attach System (QDB). The Flow Suppression Unit is designed for gas-operated self-loading rifles. Its flow-through design reduces back pressure, minimizes harmful gas exposure to the shooter, and prevents increased weapon fouling. No adjustable gas block or other gas-system adjustments are required. The Compact Streamer features a modular and multi-caliber construction. The suppression unit can be easily removed and replaced, allowing the suppressor caliber to be changed when required. The Compact Streamer is available with either an Aluminum or Stainless Steel body. The Stainless Steel body with Flow Suppression Unit 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.
