Designed to meet the needs of law enforcement agencies and civilian shooters alike, the new Trijicon HD XR night sights provide advanced target identification and allow the user to engage targets at longer distances. The front sight post is thinner than the original, giving shooters a larger field of view, which in turn enhances the ability to positively identify targets and make rapid hits if necessary. An excellent option for those that require precise target engagements at unconventional distances.
