📋 About This Mod
The MCX equivalent of the MK18 1000 Year Empire. Like that mod, I've made it so you can change the barrel length and handguards of the SIG MCX. I've also added changeable lowers and uppers for some variety.
I've added a lot of aftermarket and clone parts to the MCX. I've avoided putting in any crappy parts like red and skeletonized garbage you'd find on Facebook Marketplace or Gunbroker. I also replaced a bunch of parts with superior models
I want to thank everyone who donated and/or encouraged me so this overhaul could happen, especially my good industry friend. This mod could not have been made without you.
I've also added the most objectively attractive version of the MCX:
WHOA MCX LVAW RAAAAAAAAAAH
It uses Nuka-World 7. 62. You can patch it to use any . 300 BLK ammo you use. I personally have it using the MK18 CQBR's . 300 BLK. It also spawns on Gunners at Level 30. God knows how they found one.
The SURG upper and MCX Rattler are there too, I guess.
Things to Note
(For the love of Allah (SWT), please read these)
DO NOT USE THIS WITH MY PREVIOUS MCX ARMORY PROJECTS. DO NOT BE LIKE OMEGA4D2
THE MOD REQUIRES MY FN SCAR-L MOD AND EXTRA ATTACHMENTS PACK! THAT'S HOW YOU GET REDUCED FILE SIZES!
I actually didn't include as many things like the MK18 1000 Year Empire. I think people like having variety and I do too, but the majority don't really care about whether you have a million Aimpoint or flashlight mounts. So there's like 3-4 of each, not 10. Same goes for stuff like lasers.
I didn't include the Lancer or Midwest handguards this time. I just don't think the quality is high enough anymore. I may get them made later down with a better modeler.
I didn't touch some of the base mod's sights, like the Kobra or C79. Ugly ducklings get ignored
There is no seamless scope switching. This means that for the backup sights you see in the screenshots, there is no way to switch between the two as seen in Call of Duty or Tarkov. You would have to remove the mount and backup sight to go back to using the original scope.
I don't know what's up with the Scalarworks irons. They look aligned in Blender and Nifskope just like the base KAC irons, but I guess the gun is tilted forward ever so slightly.
Learned from my previous mistake. All cosmetic options are free.
If you're wondering why something didn't make it in from the previous projects, it's because I either forgot or discovered it came from some glorified airsoft company like NcSTAR
got lazy at a couple points, such as deciding which scopes get riser
SIG MCX Eternal Paradise is a weapon mod for Fallout 4 that overhauls Subleader's MCX, adding new attachments. With 154 endorsements and 7,307 downloads, it's a niche but popular enhancement for players using the base MCX mod.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Solid community backing with 154 endorsements and over 7,000 downloads
- Directly enhances an existing weapon mod, giving MCX users more customization options
- Focused scope: purely adds attachments, so it's a straightforward upgrade for fans of the base mod
⚠️ Cons
- Requires Subleader's MCX mod as a base, so it's useless without that dependency
- No detailed feature list, so you're going in blind on what attachments are actually added
- Compatibility risk with other mods that alter the MCX or its attachments
For Fallout 4 players who already use Subleader's MCX and want more attachment variety. Skip if you don't have the base mod or if you're looking for a standalone weapon.
💡 Beginner Tips
- Make sure you have Subleader's MCX installed first, or this mod won't work.
- Use a mod manager like Vortex or MO2 to avoid overwriting files manually.
- Check the load order to ensure this mod loads after the base MCX mod.
