Area 419 CZ 457 Improved Scope Rail – 50 MOA with Bubble Level
The Area 419 CZ 457 Improved Scope Rail provides a premium optics mounting platform for precision rimfire shooters pushing their rifles to extended distances.
Featuring 50 MOA of built-in elevation, an integrated bubble level, and a full-length dovetail clamping system, this rail is designed for demanding long-range .22 LR applications where maximizing available scope elevation is a priority.
Precision-machined in the USA from 7075 aluminum and finished in Type III black hardcoat anodizing, the Area 419 rail is an excellent addition to a custom CZ 457 build, including rifles equipped with premium Lilja match barrels and precision chassis systems.
50 MOA Built-In Elevation
The 50 MOA cant provides substantial additional usable elevation adjustment for shooters engaging targets at extended rimfire distances.
As .22 LR bullets experience significant drop beyond conventional rimfire ranges, available scope elevation becomes increasingly important. A 50 MOA scope base can help shooters make better use of their optic's adjustment range for extreme-distance rimfire applications.
This configuration is particularly attractive for dedicated long-range CZ 457 builds and precision rimfire competition.
Optic compatibility: A 50 MOA rail requires sufficient internal scope adjustment to establish a zero at the shooter's preferred distance. Some riflescopes may not have enough downward adjustment for a conventional short-range zero. Verify your optic's available adjustment range before selecting this configuration.
For shooters who need less elevation, consider the Area 419 CZ 457 30 MOA Rail or 15 MOA Rail.
Full-Length Dovetail Clamping System
Area 419 designed its improved scope rail specifically around the CZ 457 receiver dovetail.
Unlike conventional mounts relying on individual set screws, the full-length clamping system distributes clamping force consistently along the receiver, creating a secure mounting interface for precision optics.
The one-piece aluminum construction provides a rigid Picatinny platform while maintaining a dedicated fit for the CZ 457 action.
Integrated Bubble Level
The Area 419 rail incorporates an integrated bubble level directly into the scope base, providing a convenient reference for monitoring rifle cant.
The level is positioned for visibility from behind the rifle, particularly during prone and supported shooting.
This integrated design eliminates the need for a separate rail-mounted level while keeping the optics mounting system clean and compact.
Extended Picatinny Mounting Surface
The improved scope rail features additional forward mounting space, giving shooters greater flexibility when positioning longer precision riflescopes.
This extended design is especially useful on compact rimfire rifles where achieving proper eye relief can otherwise be challenging.
The rail adds approximately half an inch of height above the receiver dovetail. Choosing suitable scope rings can help maintain a comfortable cheek weld and optic position.
