Knights Mfg QDC Flash Suppressor Kit - 7.62x51mm NATO, 1/2"-28 TPI, 2" Black

The Knights Mfg QDC Flash Suppressor Kit is a quick-detach muzzle device engineered for shooters running KAC QDC suppressor systems on 7.62x51mm NATO rifles. If you're already invested in the Knights QDC suppressor ecosystem, this flash suppressor gives you a standalone muzzle brake option that works seamlessly with the same QDC mounting interface—swap between suppressed and unsuppressed configurations without tools or gunsmithing.

This is purpose-built hardware for the KAC platform. The 1/2"-28 TPI threading matches standard 7.62mm NATO muzzle dimensions, and the 2-inch length keeps your sight picture and handling uncompromised. At just under 4 ounces, it won't upset your rifle's balance or require you to re-zero. The black finish resists corrosion and blends with modern rifle aesthetics.

Whether you're running drills at the range, hunting in terrain where a suppressor isn't practical, or maintaining your QDC setup across multiple rifle configurations, this flash suppressor fits the shooter who wants modular flexibility without compromise. It's direct Knights hardware built to the same standards as their suppressors and upper receivers.

Frequently Asked Questions

Will this work with my KAC QDC suppressor?

Yes. The Knights Mfg QDC Flash Suppressor Kit uses the same quick-detach mounting interface as KAC QDC suppressors, so they swap on the same rifle without modification.

What rifles does this fit?

Any 7.62x51mm NATO rifle with a 1/2"-28 TPI muzzle. Common platforms include the SR-25, AR-10, and other modern 7.62 NATO builds that accept standard muzzle devices.

Can I use this suppressed and unsuppressed on the same rifle?

Yes. The whole advantage of the QDC system is that you can detach the suppressor and attach this flash suppressor, or remove both entirely, all without tools or re-zeroing.

Does this include the QDC mounting hardware?

This is the flash suppressor unit itself. It attaches to the same QDC quick-detach interface as your suppressor—you do not need additional mounting hardware if you already have a KAC QDC suppressor or compatible mounting system in place.
