M16A4 with acog, anpeg and optional bipod.

Textures are very high quality, also includes a weaponsound.

Converted from Exciter Guns Mini Pack by Exciter_GB (http://newvegas.nexusmods.com/mods/39561)

Note: SparkIV doesn't display the gun properly in the preview-window, that doesn't mean the gun doesn't work. It's just some bug, try it out ingame and you'll see that it works fine.
