SilencerCo ASR Flash Hider AC141 1/2x28 5.56 NATO Black Steel

The SilencerCo ASR Flash Hider AC141 delivers dual functionality as both a standalone muzzle device and quick-attach mount for ASR-compatible suppressors. This precision-machined flash hider reduces muzzle flash while providing the foundation for rapid suppressor deployment when stealth becomes critical.

What Makes This Different

Unlike standard flash hiders that serve a single purpose, the ASR system transforms this device into a quick-detach suppressor mount without compromising flash suppression performance. The patented ASR mounting system locks suppressors in place with a simple twist, eliminating the alignment issues and carbon buildup common with direct-thread attachments. Independent testing shows 95% flash reduction compared to bare muzzle, matching dedicated flash hiders while adding suppressor compatibility.

Key Features

• ASR quick-detach system for instant suppressor mounting and removal
• Precision 1/2"-28 TPI threading machined for 5.56x45mm NATO chambers
• 4140 steel construction with nitride finish resists corrosion and wear
• Three-prong design maximizes flash reduction without increasing back pressure
• Compatible with all SilencerCo ASR-mount suppressors
• Crush washer included for proper timing and installation
• Wrench flats machined for secure installation with standard tools

Field testing demonstrates reliable function across temperature extremes from -40°F to 140°F without performance degradation. The nitride coating maintains corrosion resistance through 10,000+ round counts in salt spray environments. Competition shooters report consistent zero retention when switching between suppressed and unsuppressed configurations, while tactical users appreciate the ability to rapidly deploy sound suppression without re-zeroing optics.
