Comstock Armory HUB - Titanium Recessed Plan-B Adapter (RPA) Suppressor Adapter

Comstock Armory RPA Titanium Recessed HUB Plan-B Suppressor Adapter

The Comstock RPA Titanium Recessed Adapter is a purpose-built component for shooters assembling a compact, repeatable Plan-B-pattern suppressor mounting system. It combines Grade 5 titanium, a PVD finish and clearly defined tool flats to support secure installation and convenient suppressor attachment. The product uses 1.375-24 HUB/Bravo threads and is compatible with Comstock, Rearden and other common Plan-B-pattern muzzle devices.

It converts a compatible suppressor rear interface to the widely used Plan-B-pattern mounting system, allowing quick attachment to compatible Comstock, Rearden and similar muzzle devices. The design emphasizes low mass, practical tool engagement and reduced overall system length compared with bulkier mounting solutions.

Fitment and Installation Guidance

Places the muzzle device about 0.40 in deeper than the standard LPA, so muzzle-device length and blast-chamber clearance must be checked carefully. Before attaching any suppressor, verify bullet stability and confirm that the muzzle device, adapter and suppressor are concentric. Use an appropriate alignment rod and follow the current installation instructions supplied by Comstock Armory. Some suppressor manufacturers limit warranty coverage when aftermarket mounts or muzzle devices are used, so review the suppressor manufacturer's warranty and compatibility requirements before installation.
