The Leupold Alumina flip-back lens cover kit for 40mm objectives and standard eyepieces (part no. 62990) protects both ends of a scope in one purchase rather than buying objective and ocular covers separately. Leupold machines the covers from 6061-T6 aircraft-grade aluminum, and neodymium magnets pair with triple O-ring seals to resist dust and moisture in the field. The slip-on mount installs without tools, and round covers rotate to select the shooter’s preferred opening direction. Among two-piece optics accessories for 40mm scopes, this Alumina kit covers both lens surfaces in one order.
