Sci-fi PBR Game Ready Weapon Low-poly 3D model

Here is my low-poly sci-fi weapon.I've been working on it for a long time and finally finished it.

The model separated 3 objects and each object has 2 material. Actually its not complex.I made everything in the blender so u can easily open blender and use it without creating materials from begin.Also, there is a Marmoset file and Unity package.The texture sizes of model 2048x2048 and there is a 3 texture map have for each object.

I hope you like my model and slap the like button.
