B&T Firearms
The B&T Firearms Plan B flash hider for 5.56 NATO is a dedicated muzzle device built to tame muzzle flash and protect your night vision—or your shooter's eyes—when rounds go downrange. Threaded for 1/2x28 barrels common to most 5.56 rifles, carbines, and AR-15 platforms, this stainless steel flash hider delivers the signature B&T engineering you expect from a Swiss precision manufacturer now doing business in the U.S. Whether you're running a tactical rifle, a home-defense carbine, or hitting the range, a quality flash hider is a no-brainer upgrade that works whether you're shooting suppressed or unsuppressed.
B&T's approach to flash reduction has earned respect in professional and civilian circles alike. The Plan B is designed to disrupt and scatter the bright signature that escapes the muzzle, keeping your position more concealed and your night vision intact if you're training in low light or relying on thermal or image-intensified optics. The 9-inch overall length is substantial enough to be effective without being unwieldy, and stainless steel construction resists corrosion and handles the heat cycles that come with extended shooting sessions.
Installation is straightforward for anyone comfortable with basic gunsmith work or a trip to a local builder. The 1/2x28 thread pitch is the standard for 5.56 barrels across the AR platform, so compatibility is simple—just verify your barrel is threaded. Like all flash hiders, the Plan B redirects gases and noise somewhat, so hearing protection remains essential, and don't expect it to be quiet like a suppressor would be.
| Caliber | 5.56 NATO |
| Thread Pitch | 1/2x28 |
| Material | Stainless Steel |
| Overall Length | 9 inches |
| Manufacturer | B&T Firearms |
| Model | SD-145607 (Plan B) |
If your barrel is chambered in 5.56 NATO or .223 Remington and has a 1/2x28 threaded muzzle, yes. This is the standard thread pitch for most AR-15 uppers. Verify your barrel's thread pitch before ordering.
Flash hiders and suppressors are separate devices with different purposes. This flash hider can be removed and replaced with a suppressor if you have one, but they don't work together on the same muzzle.
You receive the flash hider itself. Installation hardware or shims are not specified in the product data; confirm with Bosque Outdoors if you need additional components.
Flash hiders are effective on hunting rifles, especially in early-morning or late-evening shots where muzzle flash can affect your vision or spook game. It performs the same function on a hunting rifle as on a tactical or range gun.
