CZ-USA 40087 CZ Rings 30mm Medium Height for 457/455 Matte Black

The CZ-USA 40087 CZ Rings deliver precision mounting for CZ 457 and 455 rimfire rifles with 30mm scope tubes. These medium-height rings eliminate the guesswork of aftermarket compatibility while maintaining the tight tolerances CZ firearms are known for.

What Makes This Different

Factory-engineered specifically for CZ 457 and 455 rifles, these rings integrate seamlessly with the receiver's 11mm dovetail rail system. The medium height provides optimal scope positioning for standard objective lenses while maintaining proper cheek weld. CZ's proprietary clamping design distributes pressure evenly across the scope tube, preventing the ring marks and optical misalignment common with generic mounting solutions.

Key Features

• Factory-matched compatibility with CZ 457 and 455 rimfire rifles
• 30mm tube diameter accommodates modern tactical and hunting optics
• Medium height (approximately 0.9 inches) clears standard rifle stocks
• Matte black finish resists corrosion and eliminates glare
• Precision-machined aluminum construction for lightweight durability
• 11mm dovetail mounting system requires no gunsmithing
• Torque specifications prevent over-tightening damage

Field testing demonstrates these rings maintain zero through temperature changes and repeated handling. The medium height works effectively with objective lenses up to 50mm diameter on most CZ rifle configurations. Hunters appreciate the quick-detach capability for iron sight use, while precision shooters rely on the repeatable return-to-zero performance. The matte finish withstands harsh weather conditions without showing wear patterns.
