This 4-port design isn’t simply stacking more of the same design on the end it’s a complete redesign with each port being different. Different length ports different angle ports and different height port optimizes each one to provide an ideal function based on the pressure and volume of gas being acted on at its position. This results in optimal recoil management optimal muzzle rise control and imparts no extra sound pressure at the shooter position. Using the Hellfire Self-Timing system this brake uses the same Hellfire Universal Adapters that have been in the lineup for years and can integrate with Suppressor Mounts Hellfire Hellfire 2P and Linear Flash Suppressor.
