This idea looks clever at first, but in practice the mirrors would provide only a very limited field of view, leaving plenty of blind spots. The reflected images would also be small and harder to interpret, making it difficult to accurately judge what's happening around you. On top of that, the mirrors add unnecessary bulk to the firearm, making it more awkward to carry and maneuver, while also affecting its balance and handling. In the end, the drawbacks likely outweigh any situational awareness they provide.
