More than 700 firearms were taken in over the weekend as part of the initiative, which allowed individuals to anonymously surrender their unwanted firearms for cash.
"We're very grateful this program was such a tremendous success," Sheriff Leo P. McGuire said. "As a father and Bergen County resident, it gives me peace of mind to know we've done all we can to ensure the safety of our communities."
The two-day program netted a total of 708 eligible firearms, including two assault weapons and scores of handguns, rifles and shotguns. Numerous boxes of ammunition, firecrackers, high-powered air pistols, several defaced weapons and a cross bow were also surrendered.
The county paid out more than $47,000 for the weapons. The program was paid for with money seized from drug dealers and took place at six places of worship conveniently located all across the county.
Officials say Gun Buy Back was implemented as a proactive measure to improve the safety of local communities and households.
