CZ 457 Pro Scope Base

The CZ 457 Pro Scope Base was designed from the ground up for shooters who expect more from their rifle than a simple scope mount. We looked at what on the market and addressed all the gripes.

No More Rogue Brass Stuck in Action

Anyone who has spent enough time behind a CZ 457 has seen it happen: every once in a while, a spent case decides to eject straight up instead of out to the side. Best case, you notice and shake it out. Worst case, it bounces off your scope base and ends up back in the action, blocking the next round from loading. Now you need to do a mag change and clear the fault, all on the clock.

That’s why the our Pro Scope Base features an integrated brass deflector. It redirects those occasional high-flying cases safely away from your action, keeping your rifle running smoothly.

More Rail Where It Matters

The CZ 457 Pro Scope Base is longer than a standard scope bases, giving you extra room to position your optic exactly where you want it. Whether you’re chasing the perfect eye relief, running a larger optic, or adding accessories, the additional mounting space makes your setup far more flexible.

32mm Barell on a CZ 457? Bring it on

As CZ 457 builds continue to evolve, oversized match barrels have become increasingly popular. The CZ 457 Pro Scope Base features an aggressive front clearance cut that fits barrels up to 32 mm (1.26”) in diameter, eliminating the need to modify your scope base.

Built to Match the Rifle

Machined from a solid billet of 7075 aluminum, the Pro Scope Base combines exceptional strength with minimal weight. The hardcoat anodized finish protects the rail from wear and corrosion, ensuring it looks as good after years of use as it did on day one.

The one-piece clamping system slides directly onto the factory dovetail and locks securely in place, providing a rigid mounting platform without relying on top set screws.

Ready for Precision Shooting

A built-in 30 MOA incline gives your optic the elevation needed for extended-range rimfire shooting (up to 300m with most scopes), while also allowing you to dial in close targets that are less than 50m away. We found that 30 MOA is the sweet spot for cant that works for 99% of use cases. To top it all off, we integrated a small bubble level to make scope installation faster and easier.
