The Cross Armory Fixed Magazine Lock (FXD MAG) offers AR-15 owners a straightforward way to convert their rifle to a fixed-magazine configuration. This is commonly used to build a featureless or fixed-magazine rifle in jurisdictions that regulate detachable magazines and certain rifle features.
Designed to permanently secure the magazine to the lower receiver, this solution helps owners maintain a compliant setup without sacrificing the reliability and function of their platform. Installation is intended to be clean and low-profile, keeping the rifle's ergonomics intact.
Built by Cross Armory, a company focused on practical AR-platform accessories, this kit is a solid choice for shooters who need to adapt their build to local requirements. Always confirm your specific state and local laws before installation, as configuration requirements vary by jurisdiction.
