The Rearden Atlas Alpha 1.125-28 Thread Adapter is a compact, purpose-built interface designed to bridge short Rearden muzzle devices with popular suppressors that use 1.125-28 internal threads. Finished in a durable black nitride, this adapter offers a clean, low-profile look while maintaining secure, repeatable alignment between your host device and compatible cans such as the Rugged Obsidian 9 and Obsidian 45.

This model is ideal for shooters who want to streamline their setup by running the same suppressor across multiple short Rearden devices, including FHD, Mini, SPB, RPB, and R2S. Whether you are focused on range work, training, or general recreational shooting, the Atlas Alpha helps simplify mounting while preserving the performance of your existing muzzle devices. Its thoughtful design reflects Rearden’s reputation for precise machining and practical innovation in modern suppressor interfaces.
