Rearden Alpha Atlas

The Rearden Alpha Atlas Adapter is designed to provide a mounting interface for suppressors utilizing the 1.125x28 (Alpha) thread pattern, commonly found on models such as the Rugged Obsidian 9 and Obsidian 45. This adapter enables compatibility with Plan B-style muzzle devices, including Rearden and other industry-standard options like the Q Cherry Bomb. It is intended for use with compatible suppressors that accept standard Alpha-threaded mounts.

Constructed from 17-4 PH stainless steel (H900 heat treated) and finished with a nitride coating, the Alpha Atlas Adapter offers durability and resistance to wear and corrosion. It is optimized for use with shorter muzzle devices, helping maintain a compact overall setup. Proper installation and alignment are recommended to ensure safe and reliable operation.
