SilencerCo® ASR Closed Tine Flash Hider - 1/2x28 Thread Pitch, .223 Rem / 5.56mm NATO, Closed Tine Architecture, High-Strength Alloy Steel, Black Oxide Finish - AC5326 / 816413028308
Product Description
Traditional open-tine flash hiders are great at reducing muzzle flash, but they have a habit of ringing like a tuning fork after every shot and catching on brush or gear webbing when maneuvering in tight spots. When you need effective flash reduction and a solid mounting interface for your suppressor, a closed-tine design gives you the best of both worlds. The **SilencerCo® ASR Closed Tine Flash Hider (AC5326 / 816413028308)** offers a streamlined, non-pinging muzzle device engineered specifically for 1/2x28 threaded 5.56 NATO and .223 Rem barrels.
Precision-machined from high-strength alloy steel with a durable black oxide finish, the AC5326 features a enclosed forward ring profile that eliminates "tuning fork" resonance and prevents snagging on clothing or sling straps. Designed as an integral member of SilencerCo’s Active Spring Retention (ASR) quick-detach system, it features external threads and a taper shoulder that allow your ASR-compatible sound suppressor to mount smoothly with one hand and lock down tight, ensuring repeatable zero and reliable baffle alignment.
Engineered for seamless integration with 1/2x28 threaded 5.56 rifles and ASR suppressors, this closed-tine flash hider provides snag-free performance directly from your armorer workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The SilencerCo AC5326 closed tine flash hider comes ready for barrel installation. BARREL THREAD & SUPPRESSOR FITMENT MATRIX: Fits standard **1/2x28 thread pitch barrels chambered in .223 Rem / 5.56 NATO**. *Suppressor Fitment:* Compatible with all SilencerCo ASR mounts (Bravo/Omega ASR, Charlie ASR, Alpha ASR) and sound suppressors equipped with ASR QD systems. Workbench Setup Steps: 1. Always verify your firearm is completely clear of live ammunition with the chamber empty and magazine removed before installation. 2. Clean the muzzle barrel threads thoroughly using solvent and a wire brush. 3. Apply a small drop of high-temperature thread locker or shim set (if timing is preferred) onto the barrel threads. 4. Thread the AC5326 flash hider onto the muzzle by hand, then torque to 20-30 ft-lbs using an armorers wrench across the rear wrench flats. 5. Inspect the alignment using a 5.56 bore alignment rod before mounting your ASR suppressor for live-fire testing.*
