BT SD-145611 REDSHIFT PLAN B FLASH HIDER 5/8X24 9"

The B&T SD-145611 Redshift Plan B flash hider is a purpose-built muzzle device for 5.56 NATO rifles that balances flash signature reduction with a compact footprint. At 9 inches overall length, this stainless steel flash hider threads onto barrels with 5/8x24 pitch — the standard on most modern AR-15 platforms and 5.56 rifles. B&T's design philosophy prioritizes practical performance for shooters who need to manage muzzle flash in low-light environments, whether on the range, in tactical training, or in the field.

Flash hiders work by breaking up and cooling the expanding gases that create visible muzzle flash at the muzzle brake. The Redshift Plan B achieves this through a proven multi-prong configuration that directs these hot gases away from the shooter's line of sight — critical when shooting in darkness or relying on night vision. Unlike some designs that prioritize raw recoil reduction, this hider focuses on flash elimination, making it a solid choice if your priority is staying undetected or maintaining sight picture in dim conditions.

Construction in stainless steel means the Plan B resists corrosion and holds up to hard use. The 9-inch length strikes a balance: long enough to be effective at flash reduction, but not so lengthy that it becomes unwieldy or overly impacts the rifle's handling. Installation is straightforward for anyone with basic armorer skills or a gunsmith on speed dial — thread it on, time it as needed, and you're good to run.

Frequently Asked Questions

Will this flash hider fit my 5.56 rifle?

Yes, if your barrel has 5/8x24 threading. This is the standard pitch on most AR-15 and modern 5.56 NATO rifles. Check your barrel spec or have a gunsmith verify before purchase if you're unsure.

What's the difference between a flash hider and a muzzle brake?

A flash hider is designed to suppress visible muzzle flash by cooling and breaking up hot gases — useful in low-light shooting or when you want a lower signature. A muzzle brake prioritizes recoil reduction. The Plan B is optimized for flash control rather than recoil management.

How long is the Plan B, and will it affect my rifle's balance?

At 9 inches overall length, it adds some length to your muzzle, but it's a practical compromise between effective flash reduction and handling. Mounting it on a standard-length rifle won't dramatically change the gun's feel, though you'll want to consider it when planning your overall setup and any handguard or rail system.

Does this come pre-timed, or will I need to time it myself?

Refer to B&T's documentation for any specific instructions on installation and timing. Many flash hiders require timing to ensure proper orientation and gas flow.
