SilencerCo ASR Flash Hider, 5/8×24, .30 Cal/7.62MM, Nitride, Black
This .30 caliber/7.62mm flash hider threads 5/8×24 and mounts SilencerCo’s ASR (Active Spring Retention) system, giving you a one-hand-on, one-hand-off quick-attach interface across the Specwar, Omega, and Harvester lines. A patent-pending resonance design eliminates the tuning-fork ping of typical 3-prong flash hiders, and the locking ring keeps it from working loose under sustained fire.

What does the ASR system actually let me do?
It gives you a one-hand-on, one-hand-off quick-attach and quick-detach interface, so you can move a compatible SilencerCo suppressor between hosts fast without tools.
Which suppressors work with this flash hider?
It’s compatible with SilencerCo’s Specwar, Omega, and Harvester suppressor lines via the ASR mount system — confirm your specific model before ordering.
Will this rattle or work loose under rapid fire?
No, the ASR locking ring is designed specifically to keep the suppressor shouldered and secure under a heavy firing schedule.
What’s the “tuning-fork effect” this is supposed to avoid?
Some 3-prong flash hider designs can ring or resonate audibly under fire; this flash hider’s patent-pending design is built to eliminate that resonance.
Do I need Rocksett to install this?
Yes, a Rocksett thread locker is included and recommended for a secure, permanent installation on the barrel threads.
Can I use this flash hider without ever attaching a suppressor?
Yes, it functions as a standalone flash hider on 5/8×24 .30 caliber/7.62mm rifles even without an ASR-mounted suppressor attached.
