This is a very detailed quad model of an m-4. For best results you will need to subdivide the model which has been built with this in mind. All objects are clearly labeled and all moving parts have there translates in the correct places and are parented and grouped appropriately for easy animation. You will find the EOTech and Ironsight are on seperate layers so you can select which one you wish to render.
The textures are at 8k and include a color, normal and specular map.
