Give your CZ 457 a stable, precision-built foundation for optics with the MDT CZ457 30 MOA Black Scope Base 105076-BLK. Designed for CZ 452, CZ 455, and CZ 457 rimfire rifles, this Picatinny scope base helps you mount glass with confidence and get the most out of your rifle at longer distances. The 30 MOA incline adds helpful elevation adjustment, making it easier to dial in your scope when hunting small targets or stretching shots on the range. Machined from 6061-T6 aircraft-grade aluminum and finished with a hard anodized black coating, this rail is built to handle hard use while maintaining a clean, low-profile look. Its contoured underside is made to sit flush on the receiver and follow the geometry of the ejection port for a smooth, snag-free fit. An integrated recoil lug helps support secure alignment where the action allows, and the included TORX hardware simplifies installation. For shooters who want reliable mounting, refined fit, and added optical adjustment, this MDT scope base is a practical upgrade that delivers dependable performance every time you head to the bench or field.
