One of the most popular sights from Trijicon are their Bright and Tough Night Sights. These are three dot iron sights that have the capability to increase shooting accuracy by up to five times during night time shooting. These sights are made from metal and surrounded in silicone rubber for cushioning and shock resistance. The sapphire jewel on the top of each lamp is in place to help evenly distribute the light while simultaneously protecting the lamp from damage. While these sights come with an installation tool it is recommended that they be installed by a professional.
