Comstock Armory Ultralight Recessed Titanium Plan-B Suppressor Mount, 5/8x24 The Comstock Ultralight Recessed 5/8-24 Mount 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 5/8-24 threads and is compatible with common .900-24 Plan-B-pattern adapters, including the Comstock LPA, Q Plan-B and Rearden Atlas. The recessed body sits back over the barrel to minimize overall system length while retaining a common .900-24 Plan-B-pattern suppressor interface. Its titanium construction keeps front-end weight exceptionally low, making it well suited to lightweight rifles, compact hosts and builds where balance matters.
