Comstock Armory Full Size Plan-B Muzzle Brake, 5/8x24, .30 Cal, Black Nitride
The Comstock Armory MBL-58-30 is a full size muzzle brake combining 5/8x24 barrel threads with a Plan-B suppressor-mount interface. Its .30 Cal configuration, 17-4 PH stainless steel construction and black nitride finish identify this exact version.
The 2-inch body weighs 1.8 ounces and adds approximately 1.36 inches beyond the muzzle. These separate dimensions help distinguish the device's physical size from its contribution to the overall setup.

Recoil Reduction and Blast-Baffle Protection
The brake geometry helps reduce recoil and provides a sacrificial surface ahead of a compatible suppressor's blast baffle. The steel body combines those functions with the mounting interface, making the device useful when recoil management and suppressor compatibility are both priorities.
The rotationally symmetric body does not require timing shims. Its black nitride treatment gives the stainless steel a durable, dark finish, while the wrench flats provide a dedicated tool interface.
Compatibility and Configuration
The suppressor-side interface fits compatible 0.900-24 Plan-B adapters, including Comstock LPA, Q Plan-B and Rearden Atlas. Barrel threading, bore clearance and the suppressor's internal space must all suit the intended configuration. The muzzle device does not establish the caliber rating of the suppressor.
For a 14.5-inch pin-and-weld application, this 5/8x24 version requires the separate Comstock 5/8 spacer ring. The muzzle brake alone is not a complete pin-and-weld package.

Frequently Asked Questions
Is a suppressor included?
No. This product is the muzzle device. A compatible suppressor and suppressor-side adapter are separate components.
Does the thread pitch determine caliber compatibility?
No. Barrel threads and bore clearance are separate specifications. Both must match the firearm, and the complete suppressor system must be appropriate for the cartridge.
