DayZ - Does The SCR-17 Even EXIST?

Since the DayZ experimental Patch 1.29 released, I have been searching all over Chernarus for the elusive SCR-17. Well, experimental ended, and now months after the update, I am still searching. Join me on an epic adventure that takes me to every corner of Chernarus, every Heli crash, and convoy spawn, and NWAF more times than I can count. Does this gun even exist?
