Yankee Hill 431536A Mini QD Flash Hider Black Phosphate Steel with 1/2"-36 tpi Threads & 2.13" OAL for 5.56x45mm NATO AR-Platform

The Yankee Hill Mini QD Flash Hider is a compact muzzle device purpose-built for AR-platform rifles in 5.56x45mm NATO. It threads onto standard 1/2"-36 tpi barrels and serves dual duty: it functions as an effective flash suppressor when you're running the rifle unsuppressed, and it pairs seamlessly with YHM's quick-detach suppressor systems for shooters who want the flexibility to swap between suppressed and unsuppressed configurations. At 2.13 inches overall and 3.3 ounces, this is a lightweight option designed for today's competitive shooters and hunters who don't want to sacrifice performance for minimal footprint.

Built from black phosphate steel, the Mini QD is engineered to handle both unsuppressed shooting and the thermal stresses of running suppressed—no compromises. The quick-detach interface makes mounting and removing a YHM suppressor fast and reliable, which matters when you're setting up between stages, transitions, or hunting situations where you need to adapt on the fly. It's the kind of muzzle device that works as hard as you do without adding unnecessary length or weight to your rifle.

This is a proven choice for competitive shooters, rifle hunters, and anyone running an AR who wants the option to suppress without being locked into a permanently mounted solution. If you're already in the YHM suppressor ecosystem—or building toward it—the Mini QD is the natural partner for your barrel.

Frequently Asked Questions

What AR barrels will this flash hider fit?

The Mini QD is designed for 5.56x45mm NATO AR-platform barrels threaded 1/2"-36 tpi. This is the standard thread pitch for most AR-15s and modern 5.56 rifles.

Can I shoot this unsuppressed, or do I need to run it with a suppressor?

Yes, the Mini QD is fully capable as a standalone flash suppressor. It's engineered to perform effectively both unsuppressed and suppressed, so you're not forced to use it only with a suppressor attached.

What YHM suppressors does this work with?

The Mini QD features YHM's quick-detach interface, so it's compatible with YHM fast-attach suppressor systems. Check your suppressor's documentation or contact YHM directly to confirm specific compatibility with your model.

Is this too short to use on a rifle?

At 2.13 inches, the Mini QD is compact by design—ideal for shorter barrels, precision builds, and shooters who prioritize a tight overall footprint. It's a purpose-built choice for competitive shooting and hunting applications where length matters.
