Hello, I have compiled what I believe to be a complete list of all of the weapon related things needing updated selections for re-texturing:

AUG gun, both kinds
Colt mag
CZ550 Gun
Deagle - Only grip not covered, honestly fine as is
CZ75 gun
FAMAS gun, and sawn variant
M14 10 and 20rnd mag
MP5K 15rnd mag
P1 gun
SSG82 gun and mag
20rnd VAL mag
30rnd Vik mag
MP5_RailHndgrd
MP5_PlasticHndgrd
MP5_Compensator
MP5K_StockBttstck
M4_OEBttstck
Fal_FoldingBttstck

Through my testing I also determined that basically every single scope will need to be looked at, some of them do have valid and working selections but the lensglass is usually part of the zbytek/camo selection and gets covered too, either removing that area from the selection or simply adding the lensglass selection to the model.cfg would work fine.
