Rail Mounted Aiming/ Illuminator Laser (RAIL) The RAIL shares its DNA with the Envision MARS Miniature Advanced Rangefinder System (MARS), which was recently awarded a contract by USSOCOM for the Miniature Aiming Ranging Laser (MARL) program and has been developed and tested while integrating extensive feedback from end-users, resulting in a highly intuitive and ergonomic multi-function aiming laser (MFAL) system in an exceptionally small formfactor, weighing under 6 ounces, including the onboard, laterally mounted CR123battery, making it more resistant to recoil and weapon shock even when used on belt fed or heavy caliber weapons.
