Dark Diamond Front Sight Insert – Firefly


Dark Diamond  Dark Diamond Sight System Front Sight Firefly Inserts

The Dark Diamond Front Sight Insert Firefly glow sights incorporate the latest chemical and manufacturing technology to produce glow in darkness. The Firefly night sight upgrade will swap out with any of our standard nylon front sight inserts, for all of our products. The Fireflies come in three different colors (coral, yellow, and aqua).

Firefly insert upgrades will glow for many hours with a short exposure to a strong UV light source. Once charged, casual exposure to some ambient light will increase glow time duration. The Firefly inserts never wear out or lose their glow capabilities. One may expect decades of use with the Dark Diamond Firefly glow sights.
