The SME is a highly effective Linear Comp/Blast Can that allows for excellent shot to shot recovery & incorporates an external shroud that reduces lateral auditory reports. The brake itself is machined from a single piece of 416 stainless and is tuned for efficiency without unnecessary weight. The three port design keeps the brake short while allowing for an extremely high level of efficiency. - The outer shroud of the SME is made of Aircraft Aluminum allowing for durability without additional weight. When the Unit is assembled it allows for complete control of dynamic recoil forces while keeping the pressure wave from the shot downrange. This allows for maximum recoil control and a hearing safe environment for your Teammates or fellow shooters on the firing line. - Colors: Graphite Black - Calibers: 5.56 - Thread Patterns: 1/2-28
