Ring Top Extension – Picatinny Rail Mount CRX-30 / CRX-34

Picatinny Extension for CRX Scope Mounting Systems

Upgrade your optics system with the CRX Ring Top Extension, a precision-engineered Picatinny rail designed to replace the top half of your CRX ring. This enhanced component offers a rugged and reliable platform for mounting a variety of accessories — including red dot sights, rangefinder modules, illumination devices, and more.

Whether you’re on the range, in the field, or in a tactical scenario, this extension rail delivers added functionality without sacrificing zero retention or optic integrity. Built from durable, lightweight materials, it integrates seamlessly into your current CRX ring Picatinny extension setup for a clean, low-profile finish.

⚠️ Compatibility Notice: This product is specifically designed to work only with our proprietary CRX scope mount system. It is not compatible with rings or mounts from other brands.

Note: The CRX Ring Extension is designed for use with our IPS-30/34, FAE-L50, and SLP-23 mounts. While it can be installed on our other scope mounts, the bubble level functionality will not work on those mounts.
