Hera Arms AR15 Upper Receiver - Black HCU No Forward Assist

Hera Upper System The HUS and HCU were developed to the give customers newly designed upper receivers but still keep the Mil-Spec Spec fit. Using high quality aluminum (7075T6) makes the upper receivers a more rigid platform. We use the best CNC machines available to ensure that all dimensions are met and that the upper receiver has a tight fit. Through design tests and customer feedback, Hera now offers a clean and practical addition to its AR15 parts line. Removing the forward assist from the HCU and changing the contour of the upper gives a slim Line modern designed AR Upper System.
