LMT Defense 4 Port Regulator Brake Features The LMT Defense 4 Port Regulator Brake uses a four port venting design to redirect propellant gas upward and to the sides reducing muzzle rise and felt recoil on 5.56 chambered rifles. That reduction in muzzle movement helps shooters stay on target for faster more accurate follow up shots whether on a square range or in a dynamic shooting scenario. The 1/2x28 thread pattern is the standard for 5.56 pattern barrels so the brake installs directly without needing an adapter on most AR platform rifles. Its regulator style porting is tuned to balance recoil control with manageable muzzle blast for the shooter. Built to work with Dead Air s Xeno suppressor mount this brake lets shooters add quick detach suppressor capability to a rifle already set up for accuracy and control. Running the brake as the base for a Xeno mount means a suppressor can be attached and removed without needing to re-zero a significant convenience for anyone who switches between suppressed and unsuppressed fire. This compatibility makes the Regulator Brake a practical choice for shooters building a modular suppressor ready rifle setup. The LMT Defense 4 Port Regulator Brake is a focused recoil management solution for sale at GrabAGun for Dead Air Xeno system owners.
