SilencerCo ASR Flash Hider | AC1278 | 9/16×24 LH

The SilencerCo ASR Flash Hider (AC1278) is a threaded muzzle device finished in Black Nitride and intended for .30-caliber firearms. Engineered to reduce visible muzzle flash, it is designed for use in low-light shooting and other situations where minimizing flash signature improves follow-up shot visibility. The ASR design incorporates a resonance-suppression method to address the tuning-fork effect seen with many 3-prong flash hiders.

Common applications include low-light range training and competition shooting where muzzle flash can impair sight picture. The ASR Flash Hider also serves as a rugged muzzle accessory for shooters who prefer a durable, threaded solution for .30-caliber platforms.
