Tucson police say the final tally on guns turned in at a buyback event was 206.
Those turning in the guns for destruction received $50 gift cards. Many of the weapons turned in were old and some didn't work.
The event organized by City Councilman Steve Kozachik was held in a police station parking lot on Tuesday, the second anniversary of the Tucson shooting that wounded Gabrielle Giffords.
Police say the serial number on one gun was obliterated and that it was set aside for further investigation.
