I was wondering where it said it was an OIF vehicle, but then I looked at the title! D'oh...
Looks pretty good, but it is not the version used in OIF. It is a Desert Storm era M270 that you added newer tracks to. The version used in OIF is an M270A1 with an added bar around the TC's hatch and HALON fire extinguisher boxes on either side of the hull, among other internal and powertrain changes. Also, you have way too much soot on the LLM (Loader Launcher Module) box. Only the face of the LLM where the missiles come out gets charred/sooty.
This is an M270A1 from my Bn (1-39 FA MLRS, 3rd ID) during OIF 1, the invasion of Iraq.
Here is an M270A1 that shows the hand rail and HALON box well.
Here is another showing how the LLM doesn't get that charred and sooty, except for the front where the missiles come out.
