As gun buybacks go, this one brought in a heckuva one-day haul.

The NYPD yesterday took 182 firearms off the streets of Brooklyn — including six shotguns, seven rifles, 58 semiautomatic handguns and even an SKS assault rifle complete with attached bayonet.

The event was held at St. Peter’s Lutheran Church on Highland Place in Cypress Hills. Anyone turning in a working handgun got a $200 bank card. Rifles and shotguns earned $20 bank cards — no questions asked.

Since the NYPD-clergy program began in July 2008, more than 7,300 weapons have been turned in.
