- Uses the same patented controlled gas flow technology as the Streamer rifle suppressors, so the increase in firing rate is very small and no gases are pushed back toward the operator.
- The free-float suppression unit expands freely inside the body, so accuracy holds even when the suppressor is glowing red.
- MG flash hider threads offered for FN Mag (M240) / FN Minimi (M249) and for the PKM machine gun.
- Passes the SOCOM stress test cycles; full-auto rated with the stainless steel body.
- Designed for magnum-caliber self-loading rifles and belt-fed machine guns.
- Available in QDB, QD and QD Lock mounts only: no direct thread or HUB option.
