Wilson Combat A2 Birdcage Flash Hider - AR-15 5.56/.223, 1/2"-28 Thread, Steel Matte Finish

The Wilson Combat A2 Birdcage flash hider is a straightforward, proven muzzle device for your AR-15 running 5.56 NATO or .223 Remington. Built from steel with a matte finish, this A2-style flash hider threads onto 1/2"-28 barrels—the standard for most modern AR platforms. If you've shot an M16A1 or military carbine, you know this profile: simple, reliable, and effective at taming the bright signature that can compromise your position on a dimly lit range or in the field.

Wilson Combat's take on the classic A2 keeps the design clean and durable. The birdcage prongs break up and cool muzzle flash so you're not lighting up the shooting line or giving away your position to hunting buddies downrange. It's a no-nonsense choice for hunters, tactical shooters, and anyone building a practical AR that doesn't need complicated bells and whistles—just solid performance.

Installation is straightforward. A crush washer is included to help you time the flash hider correctly on your barrel, so the prongs align as intended. The matte steel finish resists corrosion under normal use and pairs well with most builds, from carry rifles to dedicated range guns.

Frequently Asked Questions

Will this A2 flash hider fit my AR-15?

Yes, if your barrel has 1/2"-28 threads. This thread pitch is standard on most AR-15 barrels in 5.56 NATO and .223 Remington. Check your barrel's threading before ordering; some specialty or older barrels may use different threads.

What's the crush washer for?

The crush washer helps you time the flash hider so the birdcage prongs point straight up or at the 12 o'clock position—the conventional orientation. It compresses under the castle nut or flash hider nut to lock in alignment and is part of standard AR muzzle device installation.

How much does this reduce muzzle flash?

The A2 birdcage design breaks up and dissipates muzzle flash, reducing the bright signature compared to an open muzzle. It's not a suppressor substitute, but it improves your ability to see targets and reduces the flash visible to others on the range or in the field.

Is this matte finish corrosion-resistant?

The steel matte finish provides good corrosion resistance under normal shooting and storage conditions. Like any steel component, occasional cleaning and dry storage will keep it in working order.
