I was able to finally get my new AR out to the range yesterday. I performed the Improved Battlesight Zero procedure at 50 yards and got my irons sighted in. Then I mounted my new Eotech and got that sighted in as well. During both processes, I was able to get down to 2" - 3" groups pretty well centered at my point of aim. All of this was done seated at the bench rest. Then I stood up and shot in the standing position, using the Eotech, still on the 50 yard range. My shots were consistently low and to the left of target. I would say that they were off point of aim by anywhere from 3" to 6", and just about all of them were between 6 o'clock and 9 o'clock. This is the first rifle I have ever owned, so I don't have much experience shooting rifles. I know that the problem must lie in the way that I am setting up to shoot. My rifle has a regular handguard, no vertical grip or anything. I'd appreciate any help or hints that y'all can give me to help me correct and improve my shooting. Pics of proper stance would be good too. Thank you.
