Universal Green Laser Sight for Rail-Equipped Pistols, Rifles and Shotguns The CMR-206 Rail Masteris 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.
