Mepro’s Hyper-Bright series delivers one of the brightest pistol sights available! The Hyper-Bright sights utilize a specially formulated tritium to provide an extremely bright ring in the front sight in either green, orange, or yellow, which contrasts with the rear sights to allow the shooter to focus on the front sight. This promotes faster target acquisition and works in any lighting condition. The Hyper-Bright sights are installed easily and are exceptionally durable.
