KAK Industry A2 Birdcage 5.56 NATO 1/2x28 Flash Hider - Black Phosphate

The KAK Industry A2 Birdcage Flash Hider is a classic 5.56 NATO muzzle device for the AR-15 platform, threaded 1/2x28 to fit standard 5.56 NATO AR-15 barrels. It uses the time-tested A2 birdcage design that delivers proven flash suppression while keeping your build's profile clean and traditional.

Machined from heat-treated steel for strength and durability, this flash hider is finished in a corrosion-resistant black phosphate coating. Milled flats are cut into the body so it can be torqued down with a standard wrench or armorer's tool, and overall length comes in at 1.75". A crush washer is not included, so plan to add one (or have one on hand) when installing.

This is an inexpensive, no-frills upgrade or replacement part that's perfect for completing a new AR-15 upper build, refreshing a worn-out factory hider, or simply running the classic A2 birdcage look. Installation is straightforward: thread the hider onto a properly timed 1/2x28 muzzle, snug with a crush washer, and align the top ports.
