Thank you for catching that! Implemented

Thanks Tuba, awesome work!
I noticed that the Mk 12 Mod 1 rifles from the SCAR expansion were missing an aceax config. I submitted a pr on github.

I have the JCA - Modular Carrier Remake Project loaded because it is necessary for the AEW | ALPAT MCRP Arsenal Expansion mod, maybe if I load the game without these 2 mods it will work, I'll try it now and tell you, if not I will do what you told me.

JCA- MCRP and JCA - IE both have the vests in them, it doesn't make sense to load both

I'm going to ask for you to go open an issue on my GitHub for this. Post your .rpt, modlist, and a screenshot of what you're seeing in game

Correction: I have the JCA - Modular Carrier Remake Project loaded, but I doubt it will conflict with Infantry Equipment.

From the JCA I only use Infantry Arsenal and Infantry Equipment, within Infantry Equipment are the MCRP's with their variants and camouflage patterns / colors but with your mod it only lets me select 3 patterns / colors, the variants are all available, maybe if I use Modular Carrier Remake Project, MCRP Expansion MTP and MCRP Expansion 2035 it will let me use all the camouflage patterns, however I mention that I use Infantry Equipment because I have a limitation with the mods when saving the lists in the launcher, so if I exceed a certain amount of mods the list is not saved and I have to search for them again, it is somewhat annoying, but about the problem I have with the mod it is just that, in the arsenal all the patterns appear (except 3) with that translucent white layer that does not let you select them.

Which ones specifically? I loaded this mod, Infantry Equipment, MCRP Expansion MTP, and MCRP Expansion 2035. The EAF and Green camos do not have access to Standard, Light, or Heavy variants because those are vanilla items that I left out intentionally. They are already covered in Pet Mudstone's BI & Ace aceax compat.

There seems to be a conflict with the Infantry Equipment mod, the vests are only available in 3 patterns, and the others appear locked without the possibility of being selected.
