The Rearden R2S Flash Hider 0.375 1/2-28 Square Plan B is a compact muzzle device designed to work seamlessly with Atlas, Atlas XL, and Plan B mounting systems. Machined from durable 17-4 PH H900 steel and finished in a heat treated gold tone, it offers a clean, open-prong design that helps disrupt muzzle flash while maintaining a sleek profile at the end of your barrel.

This R2S model is threaded 1/2x28, making it a strong option for rifles and pistols chambered in popular small-bore calibers that use this common thread pitch. Its square Plan B interface allows easy pairing with compatible suppressor mounts, while the included shims help you achieve proper timing during installation. Whether you are refining a range rifle or building a dedicated training setup, this flash hider reflects Rearden’s focus on precise machining and thoughtful engineering.
