The MDT ACC Elite is everything great about the ACC Premier, but better. This is the ultimate competition chassis. With increased rigidity throughout the forend and buttstock, including a buttstock to chassis connector bar, the ACC Elite has a different and distinctly solid feel to shoot. The increased torsional rigidity in the forend reduces its tendency to flex even when unweighted.
