Just got this new trijicon acog scope with the red dot sight on the top for my colt ar 15. Finally got a nice sunny day to go sight it in. This thing is awesome so much fun to shoot. After it was well sighted in I had no trouble hitting a 2 liter bottle about 250 yards out, the farthest I could set a target at this spot. I will be putting alot of rounds through it now. Both of my friends that shot it couldn't believe how nice this scope is. My new love. Sorry don't want it to sound like I'm bragging, but I'm so exited it's been sitting in my gun safe for about 3 or 4 weeks waiting for a nice day to shoot.
