Maxim Defense Hate Brake muzzle booster is designed to regulate firearm exhaust gases to ensure PDW's cycle more reliably. The primary design features include the redirection of the sound signature, decreasing the flash signature, significantly reducing recoil, and increasing accuracy. The Hate Brake locks into place with K-Taper, a patent-pending taper locking technology, replacing the need for proprietary tapered barrels. Its external shape is designed to work with M-Slot compatible hand guards.
