There was an error popping up related to the LODs for both the normal and line color versions of this vehicle. This should hopefully be fixed. I tested it a few times after subscribing, and restarting my game. The error has not popped up, and the LODs are visible.

Failed attempt to re-upload this item to remove an LOD error. Will fix this when I can. I apologize for any issues this may cause.

If things have uploaded correctly, there should now be two models: 1) the classic blue M4, and 2) a line color version.
