SOTAR Secret Shopper - Ruger AR556 - Part 1/4 - Lower Receiver
This video, the first part of a four-part series, focuses on the lower receiver of a Ruger AR556. Despite audio issues preventing a reshoot, the reviewer details several problems encountered, including stiff detents, buffer spring issues, receiver extension clocking, under-torqued and unstaked castle nuts, weak hammer springs, receiver extension not engaging buffer detents correctly, notched hammers, insufficient carrier key gaps, and issues with the magazine button and catch leading to binding with PMAGs. The reviewer also notes minor cosmetic scratches. This installment appears to be an in-depth examination of the AR-15 platform's assembly and potential defects.
