I really like these weapons but they don't have flashlights, so I made changes to their upks adding them, I thought some other people would also like flashlights on these weapons so I'm going to show you how to add them as well.

Note this only changes the conventional versions of these weapons, I'm not sure if it works on the other weapon tiers.

This mod (to add the weapons)
X2WOTCCommunityHighlander (for the +SOCKETS_TO_ADD command to work)
[WOTC] Iridar's Weapon Skin Replacer (to add the flashlight model)
My upk edits (to add functionality to the flashlight)

Step 1 download my edited upks https://drive.google.com/open?id=1TX5dVnX9RjM5KAUYKyN7fux4SSVFkJ6K

Step 2 go to this mods folder SteamApps\workshop\content\268500\1898540490

Step 3 open the Content folder and replace the upks in there with my edited upks

Step 4 go to the weapon skin replacer folder SteamApps\workshop\content\268500\1709345052\Config

Step 5 open the config file and add these lines

+SOCKETS_TO_ADD=(TEMPLATE=TLP_F_Rifle_CV, SOCKET_NAME=Light, OFFSET_X=29.948261f, OFFSET_Y=2.761644f, OFFSET_Z=5.249999f, dROLL=0, dPITCH=0, dYAW=0, SCALE_X=1.0f, SCALE_Y=1.0f, SCALE_Z=1.0f)
+SOCKETS_TO_ADD=(TEMPLATE=TLP_F_LMG_CV, SOCKET_NAME=Light, OFFSET_X=33.822338f, OFFSET_Y=2.250627f, OFFSET_Z=6.000000f, dROLL=0, dPITCH=0, dYAW=0, SCALE_X=0.990000f, SCALE_Y=1.172500f, SCALE_Z=0.900000f)

+SOCKETS_TO_ADD=(TEMPLATE=TLP_F_Sniper_CV, SOCKET_NAME=Light, OFFSET_X=31.227783f, OFFSET_Y=1.565665f, OFFSET_Z=4.000000f, dROLL=0, dPITCH=0, dYAW=0, SCALE_X=1.0f, SCALE_Y=1.0f, SCALE_Z=1.0f)

+DEFAULT_ATTACHMENT=(TEMPLATE=TLP_F_Rifle_CV, SOCKET=Light, MESH="ConvAttachments.Meshes.SM_ConvFlashLight")
+DEFAULT_ATTACHMENT=(TEMPLATE=TLP_F_LMG_CV, SOCKET=Light, MESH="ConvAttachments.Meshes.SM_ConvFlashLight")
+DEFAULT_ATTACHMENT=(TEMPLATE=TLP_F_Shotgun_CV, SOCKET=Light, MESH="ConvAttachments.Meshes.SM_ConvFlashLight")
+DEFAULT_ATTACHMENT=(TEMPLATE=TLP_F_Sniper_CV, SOCKET=Light, MESH="ConvAttachments.Meshes.SM_ConvFlashLight")

Step 6 save the file and enjoy the flashlights
