Comstock Armory Compact 30 Cal Muzzle Brake - 5/8x24 - MBC-58-30

The Comstock Armory Compact 30 Cal Muzzle Brake is a short, lightweight suppressor-ready muzzle device built for firearms with 5/8×24 muzzle threads. Its compact 1.6-inch body helps reduce recoil without adding the length of a traditional full-size brake, making it a good fit for compact semi-auto rifles and precision bolt-action setups.

The brake uses the common .900″-24 Plan-B interface, making it compatible with systems such as the Comstock LPA, Q Plan-B, and Rearden Atlas. Its rotationally symmetric design eliminates the need for shim timing, while the 17-4 PH stainless steel construction and black nitride finish provide durability under heat and repeated use.
