Sco ASR Closed Tine Flash Hider 1/2x28 .223 Caliber

The SilencerCo ASR Closed Tine Flash Hider in 1/2x28 thread is engineered for shooters who want flash reduction without the snag hazard of open-tine designs. Built to accept SilencerCo's quick-attach ASR (Active Spring Retention) mounts, this muzzle device lets you pair or swap suppressors with one hand while keeping your rifle as compact as possible. The closed-tine profile makes it a solid choice for hunters and tactical shooters working through brush or tight quarters where traditional flash hiders can catch on branches or gear.

The ASR system itself is the real workhorse here. Once you've threaded the flash hider onto your .223 barrel, any compatible ASR suppressor locks on and off without tools—no spinning, no fumbling. The integrated locking ring keeps your silencer rock-solid under rapid fire, so there's no rotation or creep even during a heavy range session. That simplicity matters when you're switching between rifles or hunting scenarios where speed and reliability count.

Designed for the .223 Remington / 5.56 NATO platform, the closed-tine design delivers effective flash reduction while staying snag-free compared to wider open-tine alternatives. It's a no-frills piece of gear that does its job—suppress muzzle flash, support quick suppressor attachment, and look the part on the end of your rifle.

Frequently Asked Questions

What suppressors work with the ASR Closed Tine Flash Hider?

The ASR flash hider is compatible with SilencerCo suppressors that use ASR mounts. Depending on the specific suppressor model, it will pair with one of three ASR mount variants: Alpha (for Harvester 300, Omega K, and Octane Series), Bravo (for Harvester EVO Hybrid 46, Harvester 338, and Omega 300), or Charlie (for Saker ASR, Chimera 300, Omega 36M, and Hybrid 46M). Verify your suppressor's mount type before purchasing.

Is the ASR flash hider quick-detach?

Yes. Once you thread it onto your barrel, any compatible ASR suppressor attaches and detaches with one hand. There are no tools required, and the integrated locking ring ensures the suppressor won't rotate or loosen during use.

What caliber / thread pitch is this flash hider for?

This flash hider is designed for .223 Remington and 5.56 NATO rifles with a 1/2x28 thread pitch on the barrel. Verify your barrel's thread pitch before purchase—using the wrong pitch can cause serious safety issues.

Why choose a closed-tine design over an open-tine flash hider?

Closed-tine designs are less likely to snag on branches, brush, or gear while moving through the field. If you hunt in thick cover or run tight-quarters drills, the closed design is more forgiving than open-tine alternatives while still delivering effective flash reduction.
