Skeletonized AR15 Skelred

I need to admit that it was pain to make this model, all those holes make it bigger than I wanted but in the middle of work I decided to just go with it...

Now about model it self... its Rigged and it have three PBR materials in 4k + materials for Vortex StrikeFire 2 red dot. Model is chunky, 72k tris + 33k for Vortex Strikefire 2.

Made in Blender.
