(CNN) A Florida man and his grandson couldn’t believe their eyes when they reeled in more than just some scrap metal and bottle caps during a magnet fishing weekend trip.
Duane Smith and his 11-year-old grandson, Allen Cadwalader, were out on a magnet fishing trip on January 30 in Homestead, a suburb of Miami, Florida, when within five minutes of their arrival, Cadwalader reeled in two sniper rifle receivers and bolt carrier groups wrapped in shrink wrap, Smith told CNN.
This was their first time magnet fishing, Smith said, and he chose a bridge with a canal near where he normally goes hiking.
