Narrative:

Taking off runway xxr we rejected our takeoff around 110 knots due to a flight control irregularity. I was performing pilot monitoring duties; and pilot flying said the control column came back into his lap at 110 knots; which I did observe; and when he moved forward the control column had an irregular input. At this point the pilot flying decided to reject the takeoff; in which we followed standard procedures and eventually returned to the gate. The flight eventually operated with a new aircraft and without incident.flight control column moved aft abruptly and felt irregular after returning to forward position.
