M4A1 w Under Barrel

M4A1 w Under Barrel


This mod though usable is not complete, upon release of the fallout 4 creation kit I intend to add functionality to the grenade launcher and the upcoming shotgun under barrel attachments. If this interests you I invite you to track the mod.

The weapon uses submachine gun animations, so they dont line up 100%.. I may create new ones to fit after the creation kit is out (assuming its possible).. alternatively if you think a different existing animation would fit better, let me know.

The weapon is craftable at the chemistry stations and mods at the weapon station.

I have included a second esp file in the mod that increases damage of some of the receivers, if you want the increased damage simply activate the second esp, loading it after the M4A1.esp.

Load order:

Attachment List (2016/03/09 (YYYY/MM/DD))
Receiver – 14 (Various stat upgrades and effects for both semi-auto and full-auto)
Magazine – 4 (Standard 30 round mag, drum mag and quick reload versions of both)
Sight – 3 (ACOG Scope (4x and 1.5x zooms) and iron sight)
Barrel – 1 (Only standard at this point)
Grip (aka Under Barrel) – 2 (M203 Grenade Launcher and 870 Masterkey)
Muzzle – 1 (Supressor)
