Product Description The AREA 419 FIREARMS CZ 457 1913 Improved Scope Rail is a precision-engineered, one-piece scope base designed specifically for CZ 457 rimfire rifles equipped with an 11mm dovetail. Built for serious precision rimfire competitors and long-range .22 LR shooters, this rail delivers 50 MOA of built-in elevation cant to help maximize scope adjustment range when pushing rounds well beyond 300 yards. Each rail is machined from a single piece of T7075 aluminum on AREA 419&';s in-house Haas VF4SS 4-axis machining center, ensuring consistent, repeatable tolerances. The clamping system locks down with uniform force along the full length of the rail for rock-solid security and zero-shift repeatability. A built-in bubble level is integrated at the rear of the rail so shooters can confirm level without lifting their head from the stock. An extended front section provides additional real estate to position optics further forward for improved eye relief. Finished in Type III black hardcoat anodize and proudly manufactured in the U.S.A., this scope rail ships with the wrench required to properly torque the clamp screws. Product Highlights 50 MOA Built-In Elevation: Provides substantial cant to extend the usable elevation travel of your scope for extreme long-range rimfire shooting. T7075 Aluminum Construction: Machined from a single billet of aircraft-grade T7075 aluminum for a lightweight yet exceptionally strong platform. Integrated Bubble Level: Rear-mounted bubble level allows quick, no-lift confirmation that the rifle is perfectly level before each shot. Extended Front Rail Section: Extra forward real estate lets shooters optimize optic placement for ideal eye relief and ergonomics. Consistent Clamping System: Engineered to apply uniform clamping force across the entire rail for repeatable, shot-to-shot return to zero.
