REARDEN R2 FH .375 1/2X28 HEAT TRT

The Rearden R2 flash hider in .375 bore with 1/2x28 threading is a compact muzzle device built for shooters running modern modular suppressor systems. If you're shooting an Atlas, Atlas XL, or Plan B platform and need a quick-detach flash hider that pairs seamlessly with your can collection, this is a straightforward choice. The heat-treated finish means it's built to handle repeated attachment and removal without degrading the mounting interface—a real consideration when you're swapping suppressors or cans between rifles.

The .375 bore size keeps exit velocity high while the flash-hiding design works to reduce muzzle signature in low-light conditions and during tactical movement. This isn't a universal device; it's engineered specifically for the Atlas ecosystem, so compatibility with your existing suppressors matters. The 1/2x28 thread pitch is a common standard, but verify your barrel is threaded to this spec before ordering.

Whether you're setting up a precision rifle, a modern sporting rifle, or a dedicated hunting gun with modular suppressor capability, the R2 fills the role of a durable, no-nonsense flash hider that doesn't reinvent the wheel—it just works with the system you've already chosen.

Frequently Asked Questions

Will this flash hider fit my barrel?

The R2 FH is threaded 1/2x28. Confirm your barrel is chambered and threaded to exactly this specification before purchasing. If you're unsure, check your rifle's documentation or have a gunsmith verify the threading.

What suppressors does this work with?

The Rearden R2 is designed as a quick-detach interface for Atlas, Atlas XL, and Plan B suppressor systems. If you own suppressors on these mounts, this flash hider will allow you to attach and remove them cleanly. It is not compatible with other suppressor platforms.

What does the heat-treat finish do?

Heat treatment hardens the material and the threaded surfaces, making them more resistant to wear and corrosion. This helps maintain a tight, repeatable interface if you regularly swap suppressors on and off the flash hider.
