📋 About This Mod
The idea behind this mod is to take a weapon that felt out of place with its name and setting, and give it a newfound purpose. The 'Assault Rifle' in Fallout 4 is based on several different WWI and WWII Machine Guns. Since Fallout 4 really lacks a decent support weapon, I took it upon myself to fill that gap, starting with the Assault Rifle, and expanding (optionally) to Miniguns and Gatling Lasers. Hopefully, this will become a new favored weapon, if not for you as a player, for your companions and settlers.
INSTALLATION NOTES
This will work best with a new game. If you install in the middle of an active game take a few days to rest and let cells reset. Any "Assault Rifle" that already exists in the world will maintain that name until you mod them. If you use an actual "AARP" .esp and notice that the attachment list has two receivers named "Standard", or an old none-automatic one, build one of the others, then toss that old one in a hole somewhere.
Features
There are two versions of this mod, each with six different install options. That's 12 choices for how you want the mod to work. Don't ask for more.
Replacer Version: This version overwrites most vanilla meshes with the new options and leaves the basic stats only mildly altered, only changing those things needed to be logical, such as swapping out materials needed to build parts, or renaming them. It is inteded to feel as integrated into the vanilla game as I could manage, and thus does things like alternate ammo in the same way as the vanilla game. This is my preferred way to use the mod.
Addon Version: This version treats the new meshes primarily as cosmetic options, and they are only slightly different, statistically, from the vanilla options. It is intended to expand the weapon's parts, and leave it open for even more to be added through other mods. Vanilla parts records (for barrels, stocks, magazines, and sights) are mostly untouched.
Both versions include:
-Thinner receiver mesh with the carry handle removed. Replacer versions also have a lighter foregrip.
-Four new barrel meshes based on classic US machine guns
-New iron sights with a lower profile to use with new barrels
-Three new stock/grip meshes. One based on the Johnson LMG and two converted from the Gauss Rifle.
- One new magazine mesh, based loosely on cloth belt holders.
Each version has six different .esps to choose from.
AssaultRifleReplacementParts or AssaultRiflePartsPack: Simply adds the new parts, either by replacing the old ones, or as additional options. Highest compatibility with other mods, especially
