SMOD Redux: M4A1-S

"The M4A1-S is an assault rifle of unknown origin, presumably the Resistance.
It appears to be the well known M4A1 carbine, but with a large holographic sight mounted on the top,
as well as an effective, durable suppressor attached to the barrel,
hence the 'S' at the end of its name."
