Description
The Rearden Low Profile Alpha Atlas Thread Adapter in nitride is a mount interface for suppressors that use low-profile style adapters with 1.125-28 inside-diameter threading, like the Omega 9k. Rearden Manufacturing machines it from 17-4 PH H900 steel, and this version carries the nitride finish rather than heat treat. It adds only 0.350 inch of length, so a short Plan B muzzle device keeps the whole stack compact. The adapter runs with Rearden muzzle devices and with other makers’ Plan B compatible designs. For an Omega 9k owner who wants to move into the Plan B system, this is the Atlas to start with.
Key Specifications
- The suppressor interface is 1.125-28, the SilencerCo Alpha thread pitch, so it matches suppressors with that inside-diameter threading.
- The finish is nitride, the alternative Rearden offers beside heat treat on this adapter.
- The material is 17-4 PH H900 stainless steel, a precipitation-hardened grade suited to a load-bearing adapter.
- Added length is 0.350 inch, which keeps the suppressor and muzzle device stack short.
- Compatible muzzle devices include Rearden’s short FHD, Mini, SPB, RPB and R2S models, the Q Cherry Bomb and other Plan B compatible designs.
