Comstock Armory Recessed Micro 30 Cal Muzzle Brake – 5/8×24
The Comstock Armory Recessed Micro 30 Cal Muzzle Brake is an ultra-low-profile mounting solution for .30 caliber firearms using 5/8×24 muzzle threads. Its recessed design is optimized for Plan-B compatible suppressor systems and adds just 0.42 inches to the muzzle, helping keep the overall setup short and streamlined.
Machined from high-strength 17-4 PH stainless steel and finished in black nitride, the brake also acts as a sacrificial baffle to help reduce wear on the suppressor’s blast baffle. Rotationally symmetric porting eliminates the need for timing with shims, while minimal suppressor protrusion helps improve compatibility with recessed-style adapters.
