Brief Real-World History

The real Spectre M4 is an Italian submachine gun designed in the 1980s by Roberto Teppa and Claudio Gritti and produced by SITES (later by Greco Sport). It is a compact, high-rate-of-fire SMG known for its distinctive casket (four-column) magazines and top-folding stock. Production in Italy ran through the 1980s and 1990s, with small runs continuing into the early 2000s; the weapon was used in several regional conflicts and sold in both military and civilian (semi-automatic) variants.
