The Lantac dragon is a massively effective muzzle brake primarily designed for the AR-15. This design is patent pending and was developed with the goal of decreasing felt recoil and controlling muzzle rise. In order to accomplish these objectives, LanTac developed the Short Energy Pulse system. This has the effects of reducing the length of the recoil. By decreasing the length of the recoil, during rapid fire strings, the recoil for the continuous shots do not stack up on each other. Without this system, the energy can overlap causing greater than optimal muzzle movement.
With this muzzle device, putting multiple shots on target is much easier due to the decreased recoil and decreased muzzle rise.
