This model is the Stock for m M93R model.
The stock folds and unfolds like the real thing for esthetic purposes, it doesnt have a locking mechanism as of yet but when it does I'll update the files.
The OBJ, STL, FBX files are all separated into their individual parts to the correct scale and the BLENDER files are there for reference or for people who dont want the models separated etc etc.
Feel free to ask questions or if you want any other format let me know and I'll see what I can do
I also have the Beretta M93R and Auto 9 in different packs on my page for individuals requirements
