KAK Industry Plan B A7 Flash Hider – 1/2×28

Flash control meets suppressor-ready versatility—precision machined for performance.

The KAK Industry Plan B A7 Flash Hider (1/2×28) is a purpose-built muzzle device that combines effective flash suppression with Plan B suppressor mount compatibility, offering an all-in-one solution for serious shooters. Its aggressive A7 prong design dissipates gases to minimize muzzle flash, enhancing visibility and control—especially in low-light conditions.

Machined from 17-4 stainless steel and finished with a rugged black nitride coating, this flash hider resists corrosion and maintains its integrity under extreme use. The tapered locking interface ensures rock-solid suppressor alignment and gas sealing without the need for shims or crush washers. Rear wrench flats make installation quick and hassle-free using a standard 13/16″ wrench.

With a .375″ bore diameter, the A7 accommodates a wide range of calibers—including .223/5.56 and 9mm—making it an excellent choice for multi-purpose AR-15 builds.
