+4 141.25 mm magazine base pad for Arex Rex Zero 1
The Toni System +4 magazine base pad for Arex Rex Zero 1 is a magazine extension designed to increase capacity by four rounds, providing a dedicated configuration for sport shooting and competition use.
When installed on the original Arex Rex Zero 1 magazine, the base pad brings the total assembled magazine length to 141.25 mm. Its dimensions are designed to meet the length limit required for use in IPSC Optic and USPSA divisions.
The base pad is designed to work with the original magazine spring, with no additional components required. This allows magazine capacity to be increased while retaining the original feeding system.
Installation is straightforward, and the base pad is secured using an internal hex set screw operated with a 1.5 mm hex key. It provides a dedicated Arex Rex Zero 1 configuration combining increased capacity, compatibility with the original spring and competition-oriented dimensions.
