This video from School of the American Rifle details the proper application of Aeroshell 64/33MS grease on AR-15 components. The instructor emphasizes using this specific grease on interfaces with dissimilar metals, such as steel barrel nuts and aluminum receivers, to ensure consistent torque values and prevent seizing over time due to environmental factors and firing residue. While other greases can be used, Aeroshell is recommended for its reliability in achieving accurate torque.
