Anti-Reflective Device
thingiverse
This is a simple Anti-Reflective Device (ARD, Killflash) that I designed for a red dot sight that has an outer diameter of 38 1/4 mm. Specifically this one (https://www.amazon.com/gp/product/B010OMQSR2/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) I purposely made diameter slightly larger so that I could use electric tape to make a custom snug fit. The honeycomb design is centered so the red dot aims directly though the center of one of the openings. The purpose of an ARD is the prevent sun reflection that may be seen by others, reduce sun reflection for yourself, and provide protection (against airsoft BB's, tree branches, etc.) this ARD weighs approximately 12 grams.
