Police say 354 guns including an Uzi submachine gun and four AK-47-style assault rifles were turned in during a one-day gun buyback program in the Bronx.
The guns were brought into three churches on Saturday in exchange for bank cards worth up to $600.
Police Commissioner Raymond Kelly said turning in guns prevents the weapons from getting into the hands of criminals.
Bronx District Attorney Robert Johnson said every gun that was removed from circulation represents an increased measure of protection against serious injury and worse.
People who want to turn in guns anonymously can also do so at police stations throughout New York City.
