Alumina flipback objective lens covers - Leupold Alumina Flipback Objective Lens Covers

Superiority at its best, No other lens cover I’m aware of compare with these. Screw in securely to scope with no obstruction of view or making ocular or objective ends of scope wider. (Doesn’t diminish clearance). Covers fold down on scope body allowing full view on the outside of the scope (this matters especially on moving targets-running deer). No noise when opening or closing. Last but not least they last forever- cold weather doesn’t make the brittle like plastic. OP had the best prices.
Everything I said about these is pretty much the opposite of the cheap plastic ones.
