KAK Industry Plan B Universal Muzzle Device 1/2x28 5.56 NATO - Black Nitride

The KAK Industry Plan B Universal Muzzle Device is a 1/2x28 threaded muzzle component designed for AR-15 pattern rifles chambered in 5.56 NATO / .223 Remington. Part of KAK's Plan B modular mounting system, this device threads directly onto a standard 1/2x28 barrel and serves as the interface for KAK's Plan B compatible suppressor mounts and HUB-spec accessories.

Finished in a durable black nitride coating, the Plan B Universal keeps a compact profile at 3.8" overall length by 1.1" height and weighs just 0.14 lb. The unit fits within typical carbine and rifle handguard profiles, making it a straightforward swap for factory 1/2x28 muzzle devices on standard AR-pattern builds.

The Plan B mounting interface lets builders alternate between a standalone muzzle device and a suppressor-ready configuration on a single barrel without re-threading or modifying the host. Standard 1/2x28 threading ensures a direct fit on most 5.56 NATO and .223 Remington AR-platform barrels.
