Rearden Atlas Alpha 1.125x28 HT Thread Adapter - Heat Treated

The Rearden Atlas Alpha is a Plan-B compatible thread adapter designed to mount suppressors with 1.125x28 inside-diameter threading onto Rearden's short muzzle devices, including the FHD, Mini, SPB, RPB, and R2S. Machined from 17-4 PH H900 stainless steel and finished with a Heat Treated surface for excellent wear and corrosion resistance, the Alpha gives shooters a simple, repeatable way to step between standard and Plan-B hub mounting systems without permanent modification to the host firearm.

The adapter adds just 0.350" of length to the muzzle, keeping suppressor builds as compact as possible while maintaining correct shoulder geometry for proper alignment and concentricity. At approximately 1.22 oz, it adds minimal weight to the end of the barrel, making it a clean way to host 1.125-28 threaded suppressors on any Rearden-compatible muzzle device and swap between hosts with confidence.
