Description
The Leupold Alumina Flip-Back Lens Cover is a screw-on objective cap designed for Leupold riflescopes with 42mm objective lenses made after 2004. It is machined from 6061-T6 aircraft-grade aluminum and finished in matte black for low-reflectivity protection. Powerful neodymium magnets hold the cover closed and triple O-ring seals protect the optic from dust and moisture.
