Installation instructions
Extract the file in your . Paks folder or a ~mods subfolder within the paks folder.
Main features
Add on weapon that is heavily inspired by the FBI HRT and regional SWAT M4s with Geissele MK4 rail, Troy sights, ERGO grip, KAC flash hider and so on. Used reference pictures and clone guides for inspiration.
Custom attachments from my Attachment Library. Such as EOTech XPS3, 552, DBAL A3, NGAL and many more!
3 in 1 mod, where you can change the rail and stock colors via stock attachments, (Black as default, OD and Tan as attachments).
Animations from the MK18.
Requirements
Check the requirements tab for mod dependencies.
Disclaimer:
Make sure you install all the requirements. Also this gun is made to me and to my tastes so what it is is what you get. Some red dot sights are best used with the NGAL or MAWL. The flashlight light ray position is weird but it is a VANILLA RoN issue, Void needs to fix it and it is listed on their known issues. Same with lasers.
If you find a valid bug, best place to reach me is on the Ready Or Mod discord and I will be glad to help and fix it. Sadly most reports are user error or really obvious game limitation stuff (like complaining sights don't fold, obviously an author can notice such things, it is disabled due to game limitations of modded weapons) so users with more knowledge about the game can easily find me and communicate properly.
Adds a Federal Colt MK4 rifle inspired by FBI HRT/SWAT builds to the game. A compact weapon mod with 148 endorsements and over 15,000 downloads, last updated in May 2026.
