📋 About This Mod
GUNSMITH EXTENDED Firearm Modification Overhaul Mod by Undyne777 & cooleo
Note from the authors, to anyone that still checks in on this regularly.
First, thank you to the FO4 Mod Community for your support on both this, and my other projects. I've dabbled in modding privately in past games, but this game has been my first foray on the scale that I have done. Your support and critiques kept me coming back and helped make this better (all 700+ endorsers, 13K+ downloaders, and 140+ comments).
Right now, due to work commitments and other personal developments, I am officially done with supporting this project. I don't have the bandwidth to do it justice. As of now (10/21/16), this project is 100% open-source to anyone who wants to take it and roll with it. Keep it going or change it up - that can be up to you. If you've enjoyed using this as much as I have, I hope you consider making it your own.
I've said it before and I'll say it again - BIG thank you to cooleo. He kept this thing going while I've been MIA. He pushed out a lot of refinements that I never thought of and for that we're all grateful. Can't wait to see what you crank out, dude!
Ever want an automatic . 50 pistol that shoots plasma rounds? 5. 56mm Hunting Rifle with cryo rounds? 5mm Submachine Gun with armor piercing rounds? Well, this is the mod for you! SOME BACKGROUND
I started out modding Fallout 4 with a little project called Caliber Conversion Kit that sought to add multiple receiver options to swap out ammo types. Even after I completed that project and moved onto other things, I still felt like there was more to do in terms of overhauling the existing weapon mod framework.
Thus, Gunsmith Extended was born. (NOT affiliated with the Weaponsmith Extended mod).
This mod does a deep dive series of changes to the existing modifications for ballistic firearms as pertains to receivers, fire modes, ammo types, and calibers. I drew on the things I learned working on my other mods to hopefully help diversify the options available when using vanilla weapons.
I hope you enjoy using it as much as I enjoyed making it! Cheers! :-)
MOD DETAILS

- Ammo Type: A cocktail of conventional and quirky ammo effect
Gunsmith Extended overhauls Fallout 4's vanilla firearm modification system by adding three new categories: Fire Mode, Ammo Type, and Caliber. It supports all vanilla and Far Harbor ballistic firearms. This mod is for players who want deeper weapon customization and more tactical variety.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Huge community trust with 2,942 endorsements and 81k downloads.
- Adds meaningful depth to weapon modding—fire modes, ammo types, and calibers change how you play.
- Covers all vanilla and Far Harbor ballistic guns, so you're not left out if you own the DLC.
⚠️ Cons
- Last updated in January 2018—might have compatibility issues with newer mods or game patches.
- Only supports ballistic firearms; energy weapons and other DLCs are left out.
For Fallout 4 players who love tinkering with weapons and want more control over their loadout. If you're into role-playing different combat styles or just want to squeeze more performance out of your guns, this is for you. Skip if you're fine with vanilla modding or prefer energy weapons.
💡 Beginner Tips
- Make sure you have Far Harbor installed if you want to mod those weapons—otherwise it's just vanilla guns.
- Check your load order: this mod changes core weapon mods, so place it after other weapon mods to avoid conflicts.
- Test fire modes and ammo types in a settlement to see how they affect recoil and damage before heading into combat.
