BREEK LOK 3QD SENTINEL CAGED FLASH HIDER

Sentinel Caged Flash Hider for Breek-LOK 3QD

Breek-LOK 3QD Compatible Muzzle Devices

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.
