My first weapon mod! Simply used nifskope to add a silencer and night scope to the service rifle, then tweaked the sound settings to make it sound silenced. Uses all vanilla content.

You can find this weapon in a gun cabinet next to the Goodsprings general store. It's also added to one of the houses in Primm (Forgot which one...)

Enjoy!
