The MDT ACC Premier Gen2 Chassis (MDT part no. 109725BLK) is a black, competition-oriented chassis built for the CZ 457 action, with a compact 15-inch overall length that suits rimfire precision shooters and smaller-stature shooters alike. It’s part of MDT’s ACC line, developed for serious rimfire and centerfire competitors who want a fully adjustable platform without stepping up to the top-tier ACC Elite. The chassis lets a shooter fine-tune length of pull and cheek height for a repeatable position behind the scope, and it accepts the same AR15-pattern grips and M-LOK/ARCA forend accessories found across MDT’s chassis lineup. For a CZ 457 owner serious about precision or PRS-style rimfire competition, it’s a direct upgrade over the factory stock.
