In Quantum of Solace, the M14 has a Sage EBR stock, though the actual butt stock resembles a Magpul PRS. It is also given a vertical fore-grip 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 M14s for reasons unknown. It is, interestingly, the only non-Walther weapon in the game that is not renamed in a manner that calls back to a previous Bond film.
In 007 Legends, it has no scope, a 20-round magazine and is semi-auto only. It's referred to as the "Faroh M55" here.
