Backup your files!

1)

Drag and drop weaponanimations.meta, weaponcomponents.meta, and weapons.meta from this download in Grand Theft Auto V\mods\update\update.rpf\common\data\ai

2)

Additionally, you may install Flashlight Overhaul's flashlight texture in update/update.rpf/x64/textures/graphics.ytd

3) 

Lastly, you will need to disable Flashlight Override in the lspdfr.ini - to do this set Ambient.DisablePlayerFlashlightOverride = true to false

Note: You do not need to install anything else. If you run into technical issues, please use the comment section. Thank you.

I take no credit for making these meta files but rather for compiling them together so we can use the flashlight overhaul, rate of fire, shoot rifles from vehicle, tactical grip, and fire extinguisher fix meta files together. ~ Joe C Wilson.

This modification was tested using custom weapon models for Grand Theft Auto 5. Actual results may vary.
