This is primarily a personal use mod, and modding is not fully supported yet, so as always: use at your own risk.

V1.1 and further will require the installation of this separate mod:
Gun Nut Rank 5
Make sure GunNut5.esp is loaded before this mod.

The purpose of the mod is to expand on and rebalance the combat rifle. I have tried to keep everything somewhat balanced, but by the nature of the mod it does make the combat rifle considerably better. All of the new modifications are not in leveled items lists, so this means that NPCs or containers will not have them, so the only means to get them is having the right gun nut rank or cheats.
