I’ve had the holosun for over a year with plenty of rounds through the gun it is mounted on the optic has been zeroed once and never has lost zero. It does have some wear on the high spots due to being on a rifle that has been in two gun competitions( in and out of rain barrels). The second optic I have is a vortex micro 3 magnifier. I’ve had this for about 5 months have run it through some training on the flat range still in great condition because the first one I used had some manufacturing problems and vortex replaces with a brand new model. Has seen light use works great.
