Rearden Alpha Atlas 1.125-28 Thread Adapter - Nitride

The Rearden Alpha Atlas is a precision thread adapter that bridges Plan B muzzle devices and suppressors with 1.125-28 internal threading, including the SilencerCo Alpha pattern and the Rugged Obsidian 9 and Obsidian 45.

Machined from 17-4 PH H900 stainless steel and finished in black nitride, the Alpha Atlas delivers the hardness and corrosion resistance needed for repeated suppressor swaps. At just 1.22 oz and only 0.350" of added length, it keeps your suppressed rifle or pistol build light and compact.

The Alpha Atlas is compatible with short Rearden devices and provides a secure, repeatable mount interface for your favorite suppressor on a Plan B muzzle platform, eliminating the need for separate direct-thread mounts when you want to run different cans on the same host.
