This video provides a detailed autopsy and functional test of two Palmetto State Armory (PSA) AR-15 upper receivers. Instructor Chad Albrecht of School of the American Rifle demonstrates how to diagnose and correct common issues such as barrel extension clocking and gas tube misalignment using specialized tools. The uppers undergo torque testing, alignment checks, and live fire evaluation to confirm reliability and proper function, concluding they are suitable for use despite minor component deficiencies.

This video details the process of changing an AR-15 barrel, transitioning from an A2 pre-ban to a post-ban configuration. Key steps include properly torquing the barrel nut between 30-80 ft-lbs to align the gas tube and using bubble levels for precise gas block installation. The demonstration emphasizes methodical execution for a reliable firearm.
