Barrett Muzzle Brake Kit .30 Cal Features The Barrett Muzzle Brake Kit .30 Cal is engineered specifically to adapt 5/8x24 MRAD barrels for use with the AM338 suppressor providing a purpose-built muzzle brake solution rather than an improvised alternative. The included shim kit and barrel washer allow precise timing and fit during installation and the Loctite 262 threadlocker ensures the brake stays secured under the recoil and gas pressure generated by .30 caliber fire. Together these components deliver a complete properly torqued installation without requiring additional hardware sourcing. The black finish provides corrosion resistance and a low-profile appearance consistent with the MRAD platform s aesthetic. Barrett engineered this kit as a direct accessory for the AM338 suppressor system ensuring dimensional compatibility and reliable suppressor indexing on every installation. For MRAD owners running or planning to run the AM338 this kit provides the correct foundation for a properly mounted suppressor-ready muzzle brake.
