Good red dot scooe - Burris 300205 XTS-135 1X - 30mm Tube Matte Xtreme Tactical SpeedDot Sight

I have used the XTS-135 for the past 11 years on a AR-15 for patrol. I qualified without any problems every department qualification. The unit was put through abuse by taking the rifle in and out of a rifle carrier in a vehicle. The red dot never had issues of getting out of accuracy when it was hit taking it out of the vehicle. I am very happy with the quality and accuracy. Burris replaced plastic optics covers free of charge when they broke. So far no problems and I will use for many years to come.
