The AAC 64141 Blackout Flash Hider is a .22 caliber muzzle device engineered to pair with AAC's 51T suppressors while taming muzzle flash on shorter barrels. Built from aerospace-grade steel and finished in SCARmor corrosion-resistant coating, this 3-prong design delivers the flash reduction you need without the durability compromises of traditional closed-end flash hiders. It threads at 1/2"-28 TPI and comes ready to install with Rocksett included.
If you're running a .22 rifle or pistol with an AAC suppressor setup, this flash hider bridges suppression with the added benefit of blast signature reduction. The open-prong geometry is inherently more robust than 4-prong alternatives and resists the wear patterns that plague closed designs—important when you're stacking components on a precision build.
Whether you're suppressing rimfire for hearing protection during practice or hunting, or simply want to minimize signature at the muzzle, this device handles both roles without the extra bulk of a full shroud. The aerospace steel construction and SCARmor finish mean it'll hold up to cleaning solvents and field use.

This hider is designed specifically for AAC 51T suppressors. While it will thread onto any 1/2"-28 TPI barrel, compatibility with other suppressor models is not specified in the product data.
The 3-prong geometry is inherently stronger and more resistant to wear and erosion than 4-prong units, and it avoids the durability issues common to closed-end designs.
This flash hider is chambered for .22 caliber (.6.56mm) and threads at 1/2"-28 TPI to fit standard .22 barrels configured with that pitch.
Yes—Rocksett thread-locker is included in the package for secure mounting.
