Narrative:

During descent; passing 6;300 ft. For 5;000 ft. I noticed a reflection off of an object just below me. I watched the object quickly pass around 50 feet below and slightly to the right of my aircraft. The object appeared to be a 4-propeller drone of some type. The encounter was quick and only lasted second. We reported the incident to ATC and followed up with a phone call on the ground.
