Trijicon Ruger SP101 Green Front Night Sight RR14F are designed and assembled with the optimum combination of strength and safety. The patented aluminum cylinder and sapphire lens construction cannot be equaled. The brightness obtained from the tritium content is focused through the sapphire lens to give the maximum possible illumination. Because the sight blades are machined from steel rather than cast, their strength is unsurpassed. Trijicon night sights are the brightest, strongest and safest.
Trijicon Bright & Tough(TM) Night Sights are iron sights that increase night-fire shooting accuracy by as much as five times over conventional sights. Equally impressive, they do so with the same speed as instinctive shooting - and without the need for batteries. Housed in a metal body and cushioned within silicon rubber, Bright & Tough Night Sights feature a unique shock- resistant design that is patented by Trijicon. 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 silicon rubber cushions to withstand shock and heavy recoil. Green lamps are warranted for 12 years from the date of manufacture.
