"These are very dangerous weapons," Metz said. "They may not have looked very pretty, but (they're) definitely operable."
The firearms collected included 348 pistols, 364 rifles and three so-called street sweepers, or shotguns that include a high capacity magazine capable of holding twelve 12-gauge shotgun shells.
The program allowed people to anonymously turn in their weapons for a shopping gift card worth up to $200 -- $100 for each handgun, rifle or shotgun turned in, and $200 for each gun classified as an assault weapon under state law. Officials distributed about $70,000 in gift cards at Saturday's event.
Police took possession of the launch tube Saturday. Police said the man who had purchased it agreed to accept a gift card as compensation if the launch tube is not returned to him, though the man indicated he wanted to keep it if he was legally able to do so.
McGinn said he wanted to plan another buyback event soon and urged more donations to the program.
Meanwhile, police said people who wanted to turn in guns could do so at any time outside a buyback program, though they wouldn't be compensated for it.
