40 MOA IS INTENDED FOR EXTENDED RANGE USE!
This rail has 40 MOA of built-in elevation. It is intended for shooters who need substantial additional scope adjustment for long-range and extreme long-range rimfire shooting.
Before choosing a 40 MOA base, make sure your optic has sufficient internal adjustment to establish your desired close-range zero.
The EGW HD CZ 457 40 MOA Picatinny Rail gives CZ 457 shooters a heavy-duty one-piece optic mounting platform designed for precision rimfire and extended-range applications.
Machined from solid 7075-T6 aluminum, the HD rail provides a rigid mounting platform while maintaining the weight advantages of aluminum.
The rail is finished with Black Type III Hardcoat Anodizing for additional surface hardness and durability.
The mount interfaces with the factory 11mm dovetail on the CZ 457 receiver and provides a full-length Picatinny mounting surface for greater flexibility when positioning your scope rings.
This version incorporates 40 MOA of built-in cant, preserving significantly more of the scope's available elevation adjustment for shooters pushing .22 LR and other CZ 457 configurations to extended distances.
Designed Specifically for the CZ 457!
This HD rail is designed specifically around the CZ 457 receiver and its factory 11mm dovetail.
Rather than mounting scope rings directly to the factory dovetail, the EGW rail provides a continuous Picatinny mounting surface.
This gives you considerably more flexibility when selecting and positioning scope rings for proper eye relief.
The rail is designed for the CZ 457 platform and should not be assumed to fit CZ 452, 453, 455, or other CZ receivers.
Installation:
Confirm that you have the correct CZ 457 rail and the correct handed configuration before beginning installation.
Clean the mating surfaces and mounting hardware before installing the rail.
EGW currently recommends applying a small amount of blue threadlocker to the mounting screws and tightening them to 20 in-lbs.
The required #6-32 x 3/4" SHC mounting screws and T-10 bit are included.
After installation, verify that the rail is fully seated and secure before installing and zeroing the optic.
Black Type III Hardcoat Anodized Finish.
After machining, the rail receives a Black Type III Hardcoat Anodized finish.
The hardcoat process increases surface hardness and provides a durable matte-black exterior for regular competition, range, and field use.
Full-Length Picatinny Mounting Surface.
Picatinny cross slots run along the rail to provide multiple positions for scope ring placement.
This flexibility makes it easier to establish proper ring spacing and eye relief, particularly with longer precision scopes and optics with limited mounting-tube space.
The one-piece design also provides a continuous mounting platform across the receiver rather than relying on separate front and rear bases.
Built for Precision Rimfire.
The CZ 457 has become a popular platform for NRL22, PRS Rimfire, precision target shooting, and long-range rimfire builds.
For shooters using high-magnification optics and dialing elevation for distant targets, the 40 MOA rail provides additional adjustment capability while retaining the strength and flexibility of the EGW HD Picatinny system.
Frequently Asked Quiestions:
Does this fit the factory CZ 457 dovetail?
Yes. The mount is designed around the CZ 457's factory 11mm receiver dovetail and converts it to a full-length Picatinny mounting platform.
Will it fit a CZ 455 or CZ 452?
No. This rail is designed specifically for the CZ 457 receiver. Other CZ rimfire models use different receiver configurations and require the appropriate mount.
What does 40 MOA do?
The rail incorporates 40 MOA of cant, preserving more of the scope's internal elevation adjustment for dialing at extended distances.
Is 40 MOA better than 20 MOA?
Not necessarily. The correct amount of cant depends on your optic, zero distance, ammunition, and intended shooting distance. A 40 MOA rail is intended for shooters who need more available elevation than a 0 or 20 MOA base provides.
Can I still zero at close range with a 40 MOA rail?
That depends on your scope's internal adjustment range. Some optics have enough adjustment to establish a conventional close-range zero with a 40 MOA base, while others may not. Check your optic's available elevation before choosing this rail.
What is the rail made from?
The HD rail is machined from solid 7075-T6 aluminum.
What finish does it have?
The rail has a Black Type III Hardcoat Anodized finish.
What hardware is included?
The rail includes #6-32 x 3/4" SHC mounting screws and a T-10 installation bit.
What torque should I use?
EGW currently recommends 20 in-lbs on the rail mounting screws with a small amount of blue threadlocker.
