EGW HD CZ 457 Picatinny Rail

• One-piece Picatinny platform: Converts the CZ 457 receiver into a full-length Picatinny mounting surface, giving more freedom to position scope rings correctly for eye relief and balance.
• Heavy-duty 7075-T6 aluminum construction: The HD design uses a stronger aluminum alloy than standard rails, helping the mount stay rigid under repeated use while keeping weight lower than steel.
• Built for the CZ 457 dovetail: This rail is made specifically for the factory 11 mm dovetail on the CZ 457, creating a secure interface without improvised adapters.
• Black hardcoat anodized finish: The matte black hardcoat surface adds wear resistance and helps the rail stand up to regular handling, ring installation, and field use.
• Extended mounting flexibility: A Picatinny rail makes it easier to use a wider range of rings and optics, which is especially useful on precision rimfire rifles set up for target shooting or hunting optics.

About the EGW Picatinny Rails Series

EGW Picatinny Rails are designed as practical optic-mounting upgrades for rifle shooters who want a more versatile interface than a factory dovetail or limited two-piece base. In the EGW lineup, this series focuses on giving rifles a one-piece Picatinny platform that simplifies ring selection and allows more freedom in optic placement. That matters on rifles used for precision shooting, hunting, and general target work, where eye relief and mounting position can make a noticeable difference.

The series is known for its machined aluminum construction and straightforward, model-specific fit. Within the family, EGW offers different elevation options such as 0, 15, or 20 MOA on short-action patterns, allowing shooters to choose between a level base or added cant for longer-range dialing. The design philosophy is simple: keep the mount rigid, keep installation clean, and provide a continuous rail that works with a broad range of modern optics and rings. A distinguishing detail in the family is the lengthwise center valley, a feature EGW originally intended to help accommodate backup iron sights on compatible rifles.

About the EGW HD CZ 457 Picatinny Rail

The EGW HD CZ 457 Picatinny Rail is a dedicated scope base for shooters who want to move beyond the factory 11 mm dovetail and build the CZ 457 around a more adaptable optic-mounting standard. For a rimfire rifle often used in precision shooting, small-game hunting, and training, that change is practical: a Picatinny rail opens the door to a much wider choice of rings and makes it easier to place the scope exactly where it needs to be.

This model stands out for its heavy-duty 7075-T6 aluminum construction. Compared with lighter-duty rail designs, the stiffer material helps create a more stable platform, which is useful when the rifle is carried often, shot regularly, or fitted with larger target scopes. The one-piece rail also gives consistent spacing across the top of the action, so ring placement is less restricted than it would be on a short dovetail section.

Its 160.00 mm length provides a generous mounting surface while still keeping the setup compact enough for a rimfire rifle. The black anodized finish suits both sporting and tactical-style builds and adds surface durability where rings clamp to the rail. Because this is an HD-pattern rail made specifically for the CZ 457 platform, it is a sensible choice for shooters who want a secure optic base for repeatable installation, easier scope setup, and broader compatibility with Picatinny-mounted accessories and rings.

About EGW

EGW, short for Evolution Gun Works, was founded by George Smith in 1991. The company began as a gunsmithing shop in Doylestown, Pennsylvania and later established itself in Quakertown, Pennsylvania, United States. EGW focuses on designing and manufacturing firearm parts and accessories, with a catalog that covers scope mounts, scope rings, red dot mounts, rifle parts, 1911 components, and thread protectors.

That background is relevant here because EGW has long specialized in the small but critical parts that determine how securely an optic interfaces with a firearm. Its reputation is built on practical, model-specific mounting solutions rather than generic hardware, which is why EGW rails and bases are commonly chosen for rifles that need a clean fit and dependable alignment.
