This video provides a clear and concise demonstration of how to install the Magpul ESK (Enhanced Safety Kit) selector on an H&K MP5-pattern firearm. Brownells Gun Tech Keith Ford guides viewers through the process, starting with a safety check, disassembling the lower receiver, removing the factory selector, installing the ESK components, and reassembling the firearm. He also highlights specific compatibility notes, stating the ESK will not fit Navy/FBI lowers or the H&K SP5 due to trigger pack differences. The video emphasizes the ambidextrous benefits of the ESK, allowing for safety manipulation without shifting grip.
