SOTAR Secret Shopper - Ruger AR556 - Part 2/4 - Bolt Carrier Groups
This video, part 2 of a 4-part series, focuses on the Bolt Carrier Groups (BCG) of a Ruger AR556. Despite audio issues that prevented reshooting, the analysis details several mechanical problems found within the BCG. These include misaligned carrier keys, issues with YFS carrier key screws, rough runs in the carrier for the bolt tail and support, and inefficient gas ring runs. The bolt itself exhibits magnetization, damaged tails, and undersized firing pin runs, leading to sticky firing pins and potential headspace issues. The video also previews a forthcoming discussion on carrier binding with PMags in part 3.
