This two-part video, "PSA Upper Receiver - Clocked Barrel Autopsy (Part 2/2)", appears to be a technical deep-dive into a specific firearm component. Given the title, it likely focuses on disassembling and examining a PSA (Palmetto State Armory) upper receiver, with a particular emphasis on issues related to a "clocked barrel." This suggests a detailed look at potential manufacturing defects, assembly problems, or performance anomalies. The content is geared towards firearm enthusiasts interested in the mechanics and troubleshooting of AR-15 platforms.
This video details a teardown and inspection of a PSA/H&R XM177 complete upper receiver, revealing significant issues with the barrel nut installation. The description highlights excessive torque (300 ft lbs) which caused the index pin to bend and gouge the receiver. The presenter also notes that PSA/H&R's representative, Mike, dismisses these findings. The presenter subsequently corrected the issues by replacing the index pin, properly lubricating and torquing the barrel nut, bedding the barrel, and using the correct jig, resulting in proper alignment of the FSB and barrel extension.
