The NYPD and the Kings County District Attorney's office held a "cash for guns" event Saturday in Brooklyn.
Police say citizens can exchange working handguns for $200 bank cards and working rifles and BB guns for $20 bank cards.
A maximum of $600 in bank cards will be rewarded even though any number of guns will be accepted.
Officers from the NYPD firing range and the Community Affairs bureau will be on hand to assist with the safe and anonymous surrender of firearms at the First Baptist Church of Brownsville on 357 Chester Street.
According to the NYPD, since 2008, the public has turned in 6,902 guns through the police department's church buy-back program. The program is organized in conjunction with borough district attorneys and local church leaders.
Police say guns also may be surrendered any day of the week to precinct station houses for a $100 reward.
