The Mean Arms Bearing Delayed Upper Receiver offers a significant improvement over traditional 9mm PCCs by utilizing a bearing-delayed blowback system. This system, featuring ball bearings with increased contact surface area, significantly reduces felt recoil and smooths the shooting impulse, making it easier to achieve rapid, accurate follow-up shots. The upper is compatible with standard mil-spec lowers and PMAGs using included EndoMag guts, allowing for easy caliber swaps and a streamlined setup for competitive shooting or range practice.
