Due to their design, honeycomb sunshades are a fraction of the length of regular sunshades, only 9mm deep. The other key advantage is they stop any reflections from the objective lens reaching the game, making the scope more covert in a hunting situation. Compatible with 2015 collection onwards. Please note, honeycomb sunshades are not compatible with the Frontier 30 range, XB/XB1 crossbow scopes or 24mm objectives(except Endurance 30 1-424 L4A Dot). Hawke metal flip-up covers cannot be installed on honeycomb sunshades.
