The M14 is an assault rifle that appears in 007: Legends. It has no scope and a 19 round magzine and is semi-auto.
In Quantum of Solace
The M14 appears in this game, simply called the M14. The version in game has a Sage EBR stock, though the actual buttstock resembles a Magpul PRS. It is also given a vertical foregrip as standard, and can be modified to use a scope, suppressor, and/or A.R.O. red dot scope in multiplayer. A scoped variant can also be used in the Sink Hole level, which seems to do twice as much damage as later unscoped M14's.
