When purchasing Trijicon or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

Improved visibility and accuracy in nighttime and low-light scenarios have been demonstrated by tests conducted on sights equipped with glowing dots compared to instinctive shooting with standard black sights. These glowing dots are composed of rugged, heavy-duty Traser® 3-Dot tritium lamps which are self-powered and long-lasting, mounted in metal cylinders that are sealed with silicone for maximum protection from breakage or leakage. Furthermore, polished sapphire crystal windows produce a bright, crisp, and accurately round aiming dot in low light, while inlaid white rings around each sapphire make the sights appear as standard white dots in daylight. For most models, installation is possible in factory dovetail or sight base.

The Trijicon Bright & Tough™ Night Sights are specifically designed for low-light and nighttime shooting, delivering up to a five-fold increase in accuracy over traditional sights. Furthermore, they provide this boost to accuracy at the same speed as instinctive shooting - without the need for batteries. Held within a metal body and protected by silicone rubber cushions, the Bright & Tough Night Sights have a shock-resistant design, protecting the lamps from puncture and solvents. Each lamp is fitted with a sapphire jewel that evenly distributes light, and the lamps are held within aluminum cylinders for additional protection from shock and recoil. The green lamps come with a 12-year warranty from the date of manufacture.
