The MDT ACC Premier Gen2 CZ 457 Right‑Handed Black Chassis Base is a precision‑engineered modular rifle Chassis Base built to elevate stability, accuracy, and adaptability for CZ 457 rimfire platforms. Featuring a rigid 15in forend with a wide, flat profile, this Chassis Base minimizes flex and torsion to create a solid shooting platform whether you’re firing from barricades, bipods, or other supported positions. Its full‑length integrated ARCA rail allows seamless attachment of bipods, tripods, and other support accessories to help you lock in your ideal shooting setup, while the precision V‑Block bedding system keeps the rifle’s action securely anchored in the Chassis Base to reduce unwanted movement under recoil and improve repeatable accuracy. Installation is straightforward and does not require gunsmithing since the action simply drops into the Chassis Base and is secured with two screws. Compatible with MDT’s optional weight kits so you can fine‑tune balance and handling, this Chassis Base combines rugged construction with thoughtful design, making it a strong foundation for precision, competition, or tactical shooting with your CZ 457 rifle.
