Smyth Busters: Is the AR-15's Dust Cover Really Necessary?
64
This "Smyth Busters" video tackles the long-standing debate about the necessity of the AR-15's dust cover. Presented by Brownells Gun Techs Caleb and Steve, the discussion explores whether the ejection port cover is truly essential for keeping dust and debris out of the rifle's action. They reference the original AR-10 and AR-15 designs by Eugene Stoner, the prevalence of slick-side uppers on high-end target rifles, and the inclusion of dust covers on modern firearms like the Sig Sauer MCX-Spear, adopted by the U.S. Army. Ultimately, the video busts the myth that the dust cover is unnecessary, with both hosts advocating for its importance, especially on combat rifles.
