A teenager and his stepfather shot each other to death in Queens on Tuesday afternoon, cops said.

The 15-year-old boy and 34-year-old man were having a dispute when the bullets rang out around 2 p.m. at 2815 Deerfield Road in Far Rockaway, cops said. The nature of the dispute wasn’t immediately clear.

But police believe both had guns and fired on each other, police sources said. Both appeared to die from their wounds.

The mom of one of the males heard the shots, cops said. It wasn’t clear if she called 911.
