A Nifskoped Light Machine Gun. It has two attachments, the vanilla extended drum, and a ACOG. There is also a unique version as well, knows as the freedom rifle (note that you don't have to use it if you don't want to). Both the regular and unique version can be bought from the Gun Runners.

Stats of the regular Combat MG: Dam:55 DPS:440
Stats of the unique Combat MG: Dam:75 DPS:525

Also the weapons are compatible with Melenia's Weapon Retextures. The weapons should not interfere with any other mods. If you want it for free you can just toggle collision to get inside the Gun Runner's stand. If you'd like to use this anywhere else just ask me via private message. The enclave armor retexture I'm using for this is alexzeit's Enclave Patriot retexture: http://www.nexusmods.com/newvegas/mods/50615/?

If you have any questions, ask. If you have any problems or suggestions let me know. I hope you all enjoy the mod!
