The Leupold Alumina flip-open cover for 36mm objectives (part no. 59040) protects post-2004 riflescopes with that objective size, and its clockable design lets a shooter rotate the cover to open in whichever direction suits their handling. Leupold machines the cover from aluminum for durable, lightweight protection, and neodymium magnetic latches pair with triple O-ring seals for a quiet, weather-resistant closure. The low-profile open position folds flat against the scope to minimize snagging during use. Among 36mm scope accessories, this Alumina cover suits hunting and precision field use.
