Luth-AR 5.5 Flash Hider 1/2x28 5.56 NATO

The Luth-AR 5.5 Flash Hider is a muzzle device for AR-15 rifles, designed to reduce muzzle flash during shooting. Its 5.5-inch overall length adds useful length for pin-and-weld builds, making it a practical option for shorter-barrel AR-15 configurations.

The device is machined from 4150 steel and finished in manganese phosphate, which the manufacturer describes as adding corrosion resistance and wear protection. It uses a 1/2x28 thread pitch and is listed for .223 Remington and 5.56x45mm NATO calibers.

It fits AR-15 rifles with 1/2x28 threaded barrels.
