The Area 419 CZ457 1913 Improved Scope Rail 7075 Aluminum 15MOA Type III Black from AREA 419 Firearms LLC delivers a precision, single-piece 11mm Dovetail rail machined in-house on AREA 419s Haas VF4SS and designed to slide onto the dovetail and clamp with uniform force across the entire rail, ensuring the CZ457 will not budge under recoil. This rail is produced from T7075 aluminum and finished with a Type III black hardcoat anodize, providing durable resistance and consistent performance in the field. Offered in a 15MOA configuration, it extends forward real estate to allow the optic to sit more forward on higher-powered scopes, which is especially beneficial when paired with the smaller rimfire stocks, helping maintain a proper cheek weld without risers. The rail is slightly taller than common set-screw models, adding roughly half an inch of height, but by pairing it with lower height rings or mounts you can preserve sight alignment and bore height. The design includes a front-loading approach to mounting so you can torque the clamp screws securely with the included wrench, yielding a stable, repeatable platform for long-range rimfire shooting up to and beyond 300 yards.
