About this flash hider
Breek Arms BRK4321 Sentinel Caged Flash Hider Black Nitride Steel 5/8"x24 Threads 30 Cal Compatible w is a flash hider in 5/8 inx24.
Match the thread pitch to your barrel (1/2x28 on most 5.56 and 9mm barrels, 5/8x24 on most .308 and 6.5mm) and the bore to your caliber. A device that is too small for the bullet is dangerous.
California note: a flash hider is a listed feature on a semi-automatic centerfire rifle with a detachable magazine. It works on a fixed-magazine (MagLock or CompMag) build. On a featureless rifle it is replaced with a thread protector or a muzzle brake. See the California Rifle Compliance Guide.
Manufacturer details
The Breek-LOK 3QD QD Suppressor Attachment system redefines quick-detach mounts, delivering unrivaled speed and simplicity. Its streamlined profile integrates seamlessly with any firearm for enhanced aesthetics and performance. The Breek-LOK 3QD Sentinel Caged Flash Hider mitigates muzzle flash by dispersing and redirecting gases, reinforced by internal threads that outperform standard flash hiders. This reduction in flash preserves a clear sight picture and prevents temporary blindness in low-light settings. Closed prongs eliminate snagging, remove the notorious ring, and bolster overall strength. The low-profile design maintains a clean, streamlined appearance on any setup.
