It's a nice model for a first try. My suggestions are:
1. It needs to have a reload animation.
2. The ironsight needs to be fixed.
3. The clip should be curved.
Thanks, im not all to good at using Milkshape 3d... im using basic shapes and moving vertexes, ill try my best.
Also, i dont know how to make/use a reload animation :(
edit-
Added textures in model and not in file... and it went reflective! lol
anyone know how to make it stable, like not recoiling upward every time you fire?
