Took the AR out this last sat for some test firing and to get the iron sites zeroed. I set up my target at 100 yards and sent few down range all were in the black of the target but the grouping sucked. I was a little low and to the left. I made an adjustment on the rear and that brought my hits right into the center of the black. I was able to get all my shots into a group about 6 " Over all I am pleased with first outing. I am going to go out again this weekend and pop off a ferw more so I can get used to the sights. Now I want to save up for a red dot, and a little trigger work and I will be a happy. I just need to practice.
