Kgm Suppressors A-Qd-Fh-S-2 Qd Flash Hider Nitride Steel 5/8"X24 Threads

The KGM Suppressors A-QD-FH-S-2 QD flash hider is a quick-detach muzzle device built to pair with KGM's suppressor line on rifles and carbines threaded 5/8x24. If you're running an R556, R556A1, R556A2, R30A1, or R30A2 suppressor and need a reliable way to mount and swap it, this flash hider gives you repeatable accuracy and rock-solid retention. The birdcage-style design manages flash while the taper mount interface and ratcheting secondary lock keep your suppressor exactly where it needs to be—shot after shot.

KGM machines this from heat-treated Chromoly steel and applies an OXyN gas nitride finish for durability against heat and corrosion. The nitride coating is tough enough for suppressed fire and field use without the maintenance headaches of bare steel. The taper mounting surface is the key to the repeatability: it's the same interface KGM uses across their suppressor line, so you know your point of impact stays consistent whether you're swapping cans or running the same setup day after day.

This is a no-nonsense piece of equipment for shooters who demand precision and reliability. Whether you're running a precision rifle, a tactical carbine, or a hunting setup with a suppressor, the A-QD-FH-S-2 handles the job without fuss.

Frequently Asked Questions

What suppressors will this QD flash hider work with?

The A-QD-FH-S-2 is designed specifically for KGM Suppressors R556, R556A1, R556A2, R30A1, and R30A2 models.

What thread pitch does this muzzle device fit?

This flash hider is threaded 5/8x24, a standard pitch found on AR-platform rifles, many bolt-action precision rifles, and other centerfire rifles.

How does the QD mounting system work?

The taper mounting surface mates with the QD interface on compatible KGM suppressors. The ratcheting secondary retention lock secures the suppressor in place and ensures the mount is repeatable—your zero and point of impact remain consistent when you attach and detach.

Is this flash hider durable?

Yes. It's forged from heat-treated Chromoly steel and finished with an OXyN gas nitride coating, which resists heat and corrosion from suppressed fire and field use.
