Housed in a metal body and cushioned within silicone rubber, Bright & Tough Night Sights feature a unique shock-resistant design. Each lamp is capped with a sapphire jewel to help evenly distribute the light while protecting the lamp from solvents and puncture. Contained within aluminum cylinders for additional protection, the lamps are mounted on silicone rubber cushions to withstand shock and heavy recoil. Instantly Visible Sight Picture In No-Light Or Low-Light Situations. Increased Daylight Dot Visibility. Enhanced Protection From Heavy Recoil And Harsh Cleaning Solvents.
