The DPX Rim-X Bolt Head Mod is a performance upgrade designed to enhance the reliability of the Zermatt Rim-X 22lr Action. Our modification service includes a newly upgraded Rim-X bolt head featuring custom CZ457 extractors and an upgraded C-clip for improved extraction. Tested extensively, this system offers superior spent case and live round ejection. Your factory bolt head and barrel can still be utilized if needed.
Key features of this service include:
Custom Rim-X Bolt Head: Replaces the factory Zermatt extractors with our in-house designed CZ457 extractors.
DPG Custom CZ457 Extractors: Made from S7 tool steel, these extractors are wire EDM cut and reprofiled for durability, ensuring hard-biting extraction under heavy use.
Enhanced Extractor Spring: Offers a 30% increased spring rate for improved performance.
Precision Machined: Extractor relief cuts performed on state-of-the-art CNC machines for superior fit and function.
The service includes testing and system functionality. Please note, while this modification forfeits your Zermatt Arms warranty, DPG stands behind the quality and reliability of our custom builds. Allow 3-4 weeks turnaround for completed rifles or barreled actions on previous orders.
