Yhm Mini Qd Muzzle Brake 9mm 5/8"-24

The Yankee Hill Machine Mini QD Muzzle Brake for 9mm with 5/8"-24 thread is a compact, quick-detach brake engineered for shooters who run suppressors but demand versatility. At just 1.6 inches long and 3.2 ounces, this brake integrates with YHM's fast-attach suppressor line while remaining fully shootable unsuppressed—no compromise on recoil management or sound signature in either configuration. Built for the competitive shooter, the precision-timed Mini QD sits tight on your barrel and comes ready to go with a shim set for perfect indexing.

Whether you're running a 9mm handgun or platform with a 5/8"-24 threaded barrel, this brake delivers YHM's reputation for no-nonsense engineering. The phosphate finish protects against corrosion, and the quick-detach design means you can swap your suppressor on and off in seconds without breaking down the firearm. That modularity saves you money if you own multiple platforms and one suppressor, or lets you shoot the gun bare when speed or simplicity matters.

Competitive shooters, action pistol competitors, and suppressor-ready 9mm builds all benefit from the Mini QD's compact footprint. If you're tired of permanently mounted brakes or awkward attachment systems, this is the quick-disconnect solution built for real shooting.

Frequently Asked Questions

Will this muzzle brake work with my YHM suppressor?

Yes—the Mini QD is designed to work with YHM's fast-attach suppressor systems. The quick-detach mechanism lets you mount and remove a compatible suppressor in seconds.

Can I shoot this brake without a suppressor attached?

Absolutely. The Mini QD was engineered to perform equally well suppressed or unsuppressed, so you get full recoil control and manageable sound without a can if you choose.

What's the thread size, and will it fit my barrel?

This brake is 5/8"-24 thread. Verify your barrel's thread pitch before purchase—5/8"-24 is common on many 9mm platforms, but some use 1/2"-28 instead. If unsure, measure or contact the barrel manufacturer.

What's included in the box?

The brake comes with a shim set, which allows you to adjust barrel timing and ensure the brake indexes correctly on your barrel for optimal suppressor alignment if you run one later.
