Trijicon HD XR night sights

For 17MOS, 19MOS, 34MOS please go with GL414-C-601091(Yellow) or GL614-C-601092(Red)


Trijicon HD XR is similar to the original HD set of sights, but the front sight post is much smaller for accurate long range shooting.


This design solves the problem where the wide front sight completely blocks the target at longer ranges, which makes aiming much harder and more guessing.


If you already have the original Trijicon HD sights, and you want to upgrade. You just need to buy the front sight and you're ready to go.


  • Reduced front sight post (0.122" wide) - Expanded field of view & increased precision sight picture for longer distances engagements.
  • Same quality has the original

truglo suppressor height night sight

For any one who wants co-witness while using a red dot on his / her Glock pistol, the suppressor height sight is the way to go.
