CZ 457 Bottom Metal & Trigger Guard Upgrade

Upgrade your CZ 457 with a premium CNC-machined aluminium bottom metal designed to replace the factory two-piece trigger guard and bottom metal assembly. Featuring a rigid one-piece construction, this upgrade delivers improved strength, enhanced durability and increased platform stability for hunting, competition and precision shooting applications.

Manufactured from 6061-T6 aircraft-grade aluminium and finished in a durable hard-anodised matte black coating, the HVHA CZ 457 Bottom Metal provides exceptional rigidity and long-term reliability while maintaining a clean, factory-style appearance.

Unlike the factory two-piece design, the one-piece construction helps eliminate unwanted movement and flex, creating a stronger and more stable interface between the action and stock. The result is a premium upgrade that enhances both performance and overall fit and finish.

Featuring an enlarged trigger guard profile, this design also provides improved access and control when wearing gloves, making it ideal for hunting and field use.

Why Upgrade Your Factory Bottom Metal?

The factory CZ 457 bottom metal utilises a two-piece design that can introduce unnecessary movement and reduced rigidity compared to a one-piece construction.

Upgrading to the HVHA Bottom Metal provides:

• Increased rigidity and structural strength
• One-piece construction for improved stability
• Enhanced accuracy potential
• Improved durability and impact resistance
• Premium fit and finish
• Enlarged trigger guard for gloved use
• Long-term reliability in demanding conditions

Whether you’re building a competition rifle, precision rimfire trainer or hunting setup, this upgrade provides a stronger and more refined foundation for your CZ 457 platform.
