The M-5 is a Sub Assault Rifle, developed by Division Delta Codenamed:Anti-Virus, for close quarters and long range fire fights. Works like a carbine and submachine gun, however this weapon fires the much smaller 5.56x19mm NATO, as well as the 5.56x45mm NATO. The M-5 didn't come out until the year 2037, 25 years after the fall of Albert Wesker and the Umbrella Corporation.
