KGM Technologies Quick Detach Flash Brake, Black Nitride 1/2×28

The KGM Technologies Quick Detach Flash Brake (brand part no. A-QD-5FB-S-1) is a steel muzzle device finished in black nitride and threaded 1/2×28 for direct-thread mounting on most 5.56/.223-pattern barrels. Built by KGM to combine flash suppression with recoil-taming brake ports, it doubles as the mounting interface for KGM’s quick-detach suppressor system, letting shooters attach and remove a compatible suppressor without re-zeroing. The black nitride finish resists corrosion and wear far better than a basic phosphate coating, making it a durable choice for a muzzle device that sees regular use.
