The Leupold Alumina flip-open lens cover for 20mm objectives (part no. 59030) protects a compact-objective riflescope while its clockable design lets a shooter rotate the cover to open in whatever direction suits their handling. Leupold machines the cover from aluminum to keep weight low while resisting field wear, and powerful neodymium magnets pair with triple O-ring seals to secure the cover against moisture and dust. The low-profile flip-open design lies flat when open, and the matte black finish minimizes glare. Among 20mm scope accessories, this Alumina cover fits post-2004 Leupold riflescopes with that objective size.
