The Area 419 CZ457 1913 Improved Scope Rail (part no. 419-ISR-CZ457-30) is machined from a single piece of T7075 aluminum on Area 419’s own Haas VF4SS 4-axis machining center, built to solve the sliding, misaligned scope bases common on rimfire dovetails. It clamps onto the CZ457’s 11mm dovetail with force that stays consistent across the entire rail, in a 30 MOA cant meant for shooters pushing a .22LR well past 300 yards.

Key Specifications

• Machined from a single piece of T7075 aluminum, in-house on Area 419’s Haas VF4SS 4-axis machining center.
• Slides onto the CZ457’s 11mm dovetail and clamps down with force that stays consistent across the entire rail.
• Finished in Type III black hardcoat anodizing.
• Cut with a 30 MOA cant for long-range rimfire shooting.
• Adds extra rail real estate at the front to move the optic forward, useful with higher-power scopes on a rimfire’s typically smaller stock.
• Sits about 1/2 inch taller than popular set-screw base models; a lower-height ring or mount keeps a similar over-bore height.
• Ships with the wrench needed for torquing the clamp screws.

Frequently Asked Questions

Does this fit my CZ457? Yes, this rail is built specifically for the CZ457’s 11mm dovetail action.

Why choose 30 MOA over another cant option? Area 419 offers this rail in multiple MOA cants; a higher cant like this one gives more elevation travel in your scope’s turret for shooting well past normal rimfire distances.

What tools do I need to install it? The rail ships with the wrench needed to torque the clamp screws; no other specialty tools are required.
