Abstract: An integrated anti-rebound mechanism with stop feature for a rail assembly. Two stop/anti-rebound pieces are individually attached at the forward end of a first rail and a second rail of the rail assembly. The stop/anti-rebound pieces engage one another when the first and second rails are in a closed position to prevent the first and second rails from moving beyond a closed position from an extended position. The stop/anti-rebound pieces also cooperate to resist movement of the first and second rails from a closed position. A third rail may be included in the rail assembly including a stop mechanism and an anti-rebound mechanism. The stop and anti-rebound mechanisms cooperate with on of the stop/anti-rebound pieces of the other rail to prevent the third rail from moving beyond a closed position, and to resist movement of the third rail from a closed position in relation to the other rail.
