Overview
Centurion Arms' CM4 forged lower receiver embodies the company's commitment to precision manufacturing and quality control. Forged from 7075-T6 aircraft-grade aluminum, each receiver undergoes Type III Class 2 hardcoat anodizing to military standards, ensuring a long service life of reliable use in demanding environments. The CM4 lower features an M16 auto pocket, making it compatible with select-fire components for those with proper licensing.
What sets the CM4 apart from basic mil-spec lowers is Centurion's attention to finishing details. All sharp edges are hand de-burred for a smooth premium finish that rivals more expensive options. Every dimension is inspected for accuracy, ensuring tight tolerances that result in superior fit with upper receivers and internal components. This level of quality control is typically found only at higher price points.
Built to mil-spec tolerances throughout, the CM4 maintains complete compatibility with all standard AR-15 components while delivering the precision fit and finish that has made Centurion a trusted name among professional users. For builders seeking forged strength with enhanced quality control and full-auto compatibility, the CM4 provides exceptional value.
