The LAMBDA PRS30 is the next evolution in precision rifle shooting muzzle brakes. It features a two-piece design consisting of the LAMBDA Muzzle Brake and the Jam Nut, which combine for an amazingly simple tool-less installation of the device. The LAMDA PRS Muzzle Brake features an 11 target crown for accuracy and a bold four chamber design that works in conjunction with the jam nut to self-tighten during every shot. The LAMBDA PRS30's chamber design virtually eliminates recoil allowing the shooter to stay on the scope and identify their impacts downrange. The first chamber allows an uninhibited flow of gas to the left and right of the shooter, while the three remaining chambers direct the gas backward acting as a buffer to help reduce the side concussion resulting in a more pleasant shooting experience.
