Sorry for the question but I'm new to blender and have recently found this gun model on Sketchfab that I would like to use https://sketchfab.com/3d-models/ak47-with-scope-d4d9720f3677485b958ceecc02f7965c. After downloading it and opening up the .fbx file in Blender, I was shown the same model but with very weird textures.
The textures folder contains the following files but I am unsure on how to apply them to the gun model in Blender.
