The H&K USP Bright & Tough Night Sight Set (Yellow) from Trijicon is a three-dot iron sight designed to improve accuracy in bright light, low light, and no light. Two glowing yellow dots in the rear sight help align the green front sight with your target. A green tritium phosphor lamp is used in the front sight since green provides more contrast against muzzle flash than other colored phosphorescent gas. The green lamp is also easier for the human eye to visibly acquire in any lighting condition. This configuration of the Bright & Tough Night Sight fits Heckler & Koch USP firearms, and is engineered to withstand the force of rapid firing and shock.
Note: Professional installation recommended.
Tritium Phosphor Illumination
Battery-free tritium phosphor lamps self-illuminate in low-light and no light. Both the front and rear sights have a white ring around the lamp window to enhance daylight visibility and contrast with the black steel body. Trijicon warrants their green phosphor lamps for a period of 12 years (5 years for orange and yellow) from the date of manufacture.
Protective Aluminum Cylinders
The tritium phosphor gas is protected by an aluminum housing and sealed with a sapphire jewel window that also protects the lamp while evenly transmitting the emitted light.
Silicon Rubber Cushion
Rubber polymer shock-mounting suspends the aluminum housing within the machined steel body, absorbing shock and ensuring reliability even after intense recoil.
Machined Steel Construction
Designed specifically to fit Heckler & Koch USP handguns.
