The MDT ACC Premier Gen2 Chassis Base for the CZ 457 in Flat Dark Earth is a high‑performance modular rifle Chassis Base built to elevate stability, precision, and versatility for competitive and precision shooters. Engineered around a compact 15in forend with a wide, thick, flat profile, it dramatically reduces flex and torsion to create a rock‑solid shooting platform when firing from barricades, bipods, or other supported positions. A full‑length integrated ARCA rail on the bottom allows seamless attachment of bipods, tripods, and accessories to help you lock in a consistent position for accurate shooting. Inside, a precision V‑Block bedding system holds the rifle’s action securely in place, minimizing movement under recoil and improving repeatable accuracy. Installation is simple and doesn’t require gunsmithing - the action drops in and is secured with two screws - and compatibility with optional MDT weight kits lets shooters fine‑tune balance to their preference. With its rugged construction and thoughtful design, this Chassis Base provides a solid foundation for enhancing the performance of your CZ 457 rimfire platform.
