Brownells
The Brownells AR-308 Flash Hider with closed tines is a no-nonsense muzzle device engineered for .308 rifles and similar mid-power cartridges. Built from machined carbon steel and finished with a QPQ hard-coat process, this 5/8"-24 threaded flash hider delivers the flash reduction you need downrange without the bulk or complexity of a suppressor. The closed-tine design provides effective flash control while maintaining a compact, classic appearance that works on virtually any AR-10 or piston rifle platform chambered in .308 Winchester, .243 Winchester, 6.5mm Creedmoor, or comparable cartridges that feed the same magazine and fire from the same bolt face.
Flash hiders matter in the real world. Whether you're training at an indoor range, hunting in low light, or running tactical drills, uncontrolled muzzle flash degrades your vision and can compromise your shooting position. The closed-tine geometry of this Brownells unit disperses hot powder gases and flash away from your sight picture, keeping you on target without the permanence or expense of a suppressor setup. The QPQ finish is a battle-tested carbide-based coating that stands up to repeated firing, weather, and the general abuse that comes with serious shooting—it won't rust through like plain steel or require babying like blued finishes.
Installation is straightforward: the 5/8"-24 thread pitch is the industry standard for .308 AR platforms, and the .320" bore clearance accommodates the full range of common mid-mag cartridges. No gunsmithing, special tools, or headspace-checking required. Brownells has kept the design clean and functional—no frills, just proven flash-reduction engineering that has worked on AR-pattern rifles for decades.
| Brand | Brownells |
| Muzzle Device Type | Flash Hider |
| Design | Closed Tine |
| Thread Pitch | 5/8"-24 |
| Bore Clearance | .320" |
| Material | Carbon Steel |
| Finish | QPQ (Black) |
| Caliber Compatibility | .308 Winchester, .243 Winchester, 6.5mm Creedmoor, and similar cartridges |
Yes, provided your rifle has a 5/8"-24 threaded muzzle. This is the standard thread pitch for most AR-10 and .308 piston-driven rifles. If you're unsure of your muzzle thread, measure the diameter and pitch or consult your rifle's manual.
The .320" bore clearance is designed for .308 Winchester, .243 Winchester, 6.5mm Creedmoor, and other mid-power cartridges that share the same bolt face and magazine platform. Do not use on rifles in smaller calibers like .223 Remington or larger magnums without verifying bore clearance.
The closed-tine geometry provides effective flash suppression by directing gases and combustion products away from the shooter's line of sight. Performance varies with powder type, velocity, and lighting conditions, but flash reduction is noticeable in low-light shooting compared to an unprotected muzzle.
No. A flash hider reduces muzzle flash and improves shooting position visibility. It does not reduce sound signature and does not require the registration, tax stamp, or compliance steps associated with a sound suppressor.
