MP28 is a modification of Bergmann MP18 gun. This model consists of 16k tris (13k if the belt doesn't count) and two 4096 textures.
This model is an experiment for me, so as there was no actual bake from highpoly model, and no highpoly was made for this one. Normal map was created using #pixaflux software which allows baking "rounded" edges straight to the low poly model.
