The CMR-206 Rail Master is a compact, yet powerful, universal green laser sight designed to fit rail-equipped pistols, rifles and shotguns. The laser sight fits onto virtually any firearm with a modern (M1913 Picatinny or Weaver-style) accessory rail. Ambidextrous control tabs allow the user to instantly activate or deactivate the laser. It offers 3 modes of operation: Momentary, Strobe, and Constant-On. This allows the user to easily set their mode based on personal need or preference. The unit is quickly and easily user-installed in moments and can be painlessly transferred from firearm to firearm. The CMR-206 is securely fastened using Crimson Trace's Secure Lock Technology.
