The same size as the M3, and M2 work on the M4, front and rear. The front does block the batt. compartment, but you will only need to take it off every 8 years or so it shouldn't be to big of a deal.

I stopped using covers a few years ago.. that solved my problem... Simple.. nothing to flip or snap off or pull off... like the dot.. always on and ready to go...
