Back in 016 when the ML25 arrived I emailed Chris and asked if he could make a glass lens for the new ML25. His response was "What? Maglite has a new flashlight model?" I responded "heck yeah bro, WalMart sells them".
A few days later I got an email asking for my addy. As a thanks for the info he sent me a hard coat ultra clear polycarbonate lens. I have bought several lenses from Chris over the years and they always fit correct.
