The Aero Precision M5 18in .308 SS Complete Upper Receiver is not guaranteed to fit DPMS pattern lower receivers. The M5 shares compatibility with several DPMS Gen 1 parts and components. However due to different variances within that category, Aero Precision cannot guarantee that all DPMS Gen 1 style lower receivers and components are compatible.
