This video debunks the myth that aluminum AR-15 gas blocks are a good idea. Brownells Gun Techs Caleb and Steve explain that while aluminum saves weight and is easier to manufacture, the intense heat and corrosive gases from firing will erode an aluminum gas block over time, leading to failure. They emphasize that steel is the superior material for gas blocks due to its durability, just like the barrel. The video strongly advises checking aluminum gas blocks for wear and opting for lightweight, low-profile steel alternatives to avoid potential failure.
