SilencerCo AC1561 ASR Flash Hider 9mm 13.5x1 LH Thread Black Steel

The SilencerCo AC1561 ASR Flash Hider delivers superior muzzle flash reduction while serving as a quick-detach mounting platform for ASR-compatible suppressors. This precision-machined flash hider eliminates the bright signature that reveals shooter position in low-light conditions.

What Makes This Different

Unlike standard flash hiders that only reduce muzzle flash, the AC1561 incorporates SilencerCo's proprietary ASR (Advanced Suppressor Ready) mounting system. The integrated taper mount design ensures repeatable zero when attaching and detaching suppressors. Heat-treated steel construction withstands sustained rapid fire that would damage aluminum alternatives.

Key Features

• ASR quick-detach mounting system for instant suppressor attachment
• 13.5x1 left-hand threads specifically engineered for 9mm applications
• Heat-treated steel construction rated for full-auto fire schedules
• Taper mount interface maintains consistent zero return
• Black nitride finish resists corrosion and wear
• Compatible with all SilencerCo ASR suppressors
• Reduces muzzle flash signature by 85% compared to bare muzzle

Field testing demonstrates consistent flash suppression across various ammunition types, from subsonic loads to high-velocity defensive rounds. The ASR system locks suppressors with 15 foot-pounds of torque, preventing baffle strikes during rapid strings of fire. Law enforcement agencies report zero shift of less than 0.5 MOA when transitioning between suppressed and unsuppressed configurations.
