Ryan Watson pleaded guilty after two other Americans were sentenced in the past week.

The first, a Pennsylvania man, received a yearlong suspended sentence and a $6,700 fine last week, and the second, a Virginia man, was given time served and a $9,000 fine on Tuesday.

Watson and his wife were leaving the island in April when the four rounds were found in Watson's carry-on luggage.

Watson is expected to be sentenced next month.
