Unsatisfied - Trijicon Glock Suppressor Night Sights - Green Lamps

Recieved the suppressor sights a couple months ago and still can't even put them on. It took optics planet forever to ship the product. When I finally got them something was wrong with them. The front sight screw will only go in a couple threads. Still waiting on the replacement screw. Although I'm pretty sure that's not gonna fix the issue. So, will have to send it back in after all this waiting. Extremely disappointing for a company with such a good reputation
