KAK Industry PLAN B K415 Flash Hider 5/8x24 .375 Bore – AR-15 / .223/5.56

The KAK Industry PLAN B K415 Flash Hider reduces muzzle flash while providing a quick-attach mount for compatible suppressors. The .375-inch bore diameter accommodates .223/5.56 projectiles with adequate clearance, and the 5/8x24 thread pitch fits standard AR-15 barrels chambered in .223 Wylde, 5.56 NATO, and similar cartridges.

Machined from steel with a black finish, this flash hider installs with standard armorer's tools and a crush washer or shim kit for timing. The PLAN B system allows rapid suppressor attachment when used with compatible quick-detach mounts. Verify suppressor compatibility and proper alignment before use.
