The Cross Armory CRSM Safe Mag transforms standard AR15/M4 platforms into compliant configurations without permanent modifications. This precision-machined magazine lock system allows shooters to maintain their rifle's functionality while meeting California's fixed magazine requirements.
What Makes This Different
Unlike welded or epoxied solutions, the CRSM Safe Mag provides a reversible compliance option that preserves the rifle's original components.

Installation takes minutes with basic tools, and the unit can be removed completely if regulations change or the rifle moves to a different state.Key Features
