Halo 4 Battle Rifle

I don't think you understand the concept behind High-poly to normal map workflow.

That's the triangles in the 3ds Max scene. (I.E the high-poly version)
The Low poly Br is around 7000 with a normals map. (The one that goes in the game)

The low poly will retain most of the detail of the low poly at a much lower performance cost.
