I created This model from scratch within Blender, based on the Eotech holosight. Its dimensions are accurate to life and the Picatinny mount is to scale.
The origin is set to the back middle of the Picatinny so it is ready to be added to your game with a sensible attach point.
I have changed the logo and branding to my own custom stuff to reduce any potential legal issues about using this item in your game. (Please keep in mind it is not my responsibility for any legal issues you might face for using this model in your game).
Please let me know if you have any issues with using the model.
