DESCRIPTION
Loosely inspired by some of the piston-driven AR derivatives available on the market such as the Robinson Armaments XCR and LWRC M6, as well as by bufferless systems such as the Z-M LR-300 and SIG MCX, I wanted to create a weapon using pieces from every assault rifle-style gun in the game.

I started with the base game Marksman Carbine mesh and removed everything except the receiver and pistol grip before fattening up the body slightly. I then added the stock from the Light Machine Gun, the rear sight from the legacy content Chinese Assault Rifle, and the barrel, magazine, and handguard from the legacy content G3 rifle.

Gameplay-wise, this weapon is cloned from the Assault Carbine, but takes 5.56mm ammunition and therefore has the same damage output as the Service Rifle. It can be modded with the 10mm Pistol Silencer and 9mm Pistol Scope. I've also added the weapon to all the appropriate form lists, so that all perks and challenges that affect fully-automatic rifles will work as expected.


LOCATION
The weapon can be purchased from the Gun Runners and other vendors across the Wasteland, or found in random loot drops. Of course, if you're feeling lazy, you can always use the following console command (Substitute ## with the Mod Index of the plugin in your load order):

player.AddItem ##000ADE 1;Gives 1 Special Purpose Carbine

INSTALLATION
Extract all the files in the archive to your New Vegas data folder (which is the same folder where FalloutNV.esm is located) and then enable the ESP either in your mod manager of choice, or under "Data Files" in the launcher that runs when you start up New Vegas.
