I've been using one for well over ten years. Both my Benelli SBE2 and Mossberg 835 sport an Aimpoint 9000SC red dot scope on top of them. The Aimpoints are practically indestructible, can withstand the heaviest recoil and get 50,000hrs battery life. I also put a Burris FFIII on my daughter's Mossberg 510 mini Turkey Thug. I hunt predators at night at night and the red dots work great for that situation as well.
