Comstock Armory Ultralight Recessed 5/8-24 Plan-B Suppressor Mount
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.

Minimal Length and Weight
This mount is purpose-built for shooters who want a simple Plan-B interface with almost no added muzzle length. The symmetrical profile does not require timing, and the titanium body provides a strong, corrosion-resistant mounting component without the mass of a conventional steel muzzle device.

Fitment and Installation Guidance
Fits barrels up to 0.750 in diameter; verify barrel shoulder, adapter engagement and suppressor alignment. 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.

Frequently Asked Questions
What mounting system is the ULR-58 designed for?
It is designed around the Plan-B-pattern ecosystem and the specific 5/8-24 interface listed above. Compatibility depends on the complete suppressor, adapter, muzzle-device and barrel configuration.
Does the Ultralight Recessed mount need to be timed?
No. The rotationally symmetrical design is intended to install without timing shims. Use the correct tools and follow the manufacturer's torque instructions.
How do I confirm suppressor fitment before firing?
Check every thread specification, available blast-chamber depth, muzzle-device length and caliber rating. After installation, verify alignment with a proper alignment rod and follow all firearm, ammunition and suppressor manufacturer instructions.
Use only on a compatible firearm and suppressor system. Installation should be performed by a qualified person when the user is not fully familiar with muzzle-device or suppressor-mount installation.
