About this flash hider
Luth-Ar Early A1 Duck Bill 5.56 NATO/223 Rem 1/2"X28 Flash Hider Black is a flash hider for AR-15 in 1/2-28 for .223/5.56.
Match the thread pitch to your barrel (1/2x28 on most 5.56 and 9mm barrels, 5/8x24 on most .308 and 6.5mm) and the bore to your caliber. A device that is too small for the bullet is dangerous.
California note: a flash hider is a listed feature on a semi-automatic centerfire rifle with a detachable magazine. It works on a fixed-magazine (MagLock or CompMag) build. On a featureless rifle it is replaced with a thread protector or a muzzle brake. See the California Rifle Compliance Guide.
Manufacturer details
The Vietnam War era’s distinctive “Duck Bill” flash suppressor was an iconic firearm accessory. Designed for the Colt Commando and CAR-15 rifles, its unique shape earned it the nickname due to its resemblance to a duck’s bill. Introduced in the 1960s, the suppressor served to reduce muzzle flash, improving the shooter’s visibility in low-light conditions. Its historical significance lies in its association with the compact and specialized firearms used by American forces during the Vietnam War.
