Luth-Ar
The Luth AR 5.5" flash hider is a practical muzzle device for AR-15 rifles built to extend shorter barrels and tame muzzle flash on the range or in the field. Built from 4150 steel with a manganese phosphate finish, it threads on with a standard 1/2x28 pitch and works reliably with both .223 Remington and 5.56x45mm NATO ammunition—the dual-caliber compatibility makes it a solid choice if you run either round or plan to shoot both.
Flash hiders serve a dual purpose: they reduce visible muzzle signature (especially useful in low-light conditions or tactical scenarios) and add length to the overall package, which can help with barrel harmonics and sight radius. This Luth AR piece is straightforward in design and proven in use by shooters who want a no-frills, functional upgrade without breaking the bank.
The manganese phosphate finish provides corrosion resistance and a matte appearance that blends with most AR builds. It's a direct-attach muzzle device—no special tools or adapters required beyond a wrench to snug it to your barrel's threads. Whether you're running a short-barreled rifle for defensive use, hunting, or general range work, this flash hider adds utility and presence to your setup.
| Brand | Luth AR |
| Product Type | Flash Hider |
| Length | 5.5 inches |
| Material | 4150 Steel |
| Finish | Manganese Phosphate |
| Thread Pitch | 1/2x28 |
| Compatible Calibers | .223 Remington, 5.56x45mm NATO |
| Platform | AR-15 |
Yes, as long as your barrel has a standard 1/2x28 thread pitch. This is the most common thread size for AR-15 platforms. If you're unsure of your barrel's thread pitch, check with your barrel manufacturer or contact us before ordering.
Absolutely. The Luth AR 5.5" flash hider is designed to work reliably with both .223 Remington and 5.56x45mm NATO ammunition.
The length serves two main functions: it extends your barrel's overall sight radius (useful if you're running iron sights or a magnified optic), and it helps reduce visible muzzle flash by redirecting and dissipating the blast away from the shooter. On shorter barrels especially, this can make a noticeable difference in low-light shooting.
The flash hider threads directly onto your barrel. You'll need a wrench or muzzle device wrench to tighten it securely, but no special tools or adapters are required.
