Approximately XA:11;  Pilot Flying and I were on the ILS 27R  to OPF. Weather was good; we could see the runway from 10+ miles. I was Pilot Monitoring. About 3-4 miles from the runway; on course and glide path with autopilot engaged; I saw a bright reflection to our left; about 10 o'clock low.  It was obviously not air traffic; nothing on the TCAS. It quickly moved left to right across our flight path. Passed under the right wing. Appeared to be climbing.  It looked no larger than a lunchbox; but was certainly flying; not just blowing in the wind.  It was a shiny metallic color; not a bird.Aggressive enforcement of laws concerning drone flights in vicinity of airports.
I was on an ILS approach to Runway 27R to OPF.  The weather was VFR and we could see the runway from 10+ SM out.  I was the Pilot in Command - flying pilot.  About 3-4 miles from the runway Pilot Monitoring and I saw a bright reflection to our left; about 10 o'clock low.  It was obviously not air traffic; nothing on the TCAS.  It quickly moved left to right across our flight path.  It passed under the right wing.  It appeared to be climbing.    It did not look very large but was certainly flying and not just blowing in the wind.  It was a shiny metallic color and not a bird.  No evasive action was needed on our  part and none was taken.  Pilot Monitoring reported this object to the OPF tower as we continued on the approach.  We landed safely without incident and cleared the runway and taxied to the ramp.  Possibly this was a drone.If this was a drone being flown around and just to the east of the OPF airport; try and find out who was doing this.
