Paul Furlong played a leading role as Barnet dealt Gillingham's automatic promotion hopes a major blow.
The 40-year-old broke the deadlock with a close-range header following a fine cross from John O'Flynn.
Barnet scored again in the 54th minute when Furlong was upended by Mark Bentley, allowing O'Flynn to net his 18th goal this season, from the spot.
Ex-Bee Simon King almost pulled a goal back but his shot curled wide and Furlong was denied a second late on.
