First, have fun! F class is a great, simple, discipline, and very rewarding.
Second, your AR is not a 1/4 minute gun, and you are not shooting 1/4 MOA - at least not in the context of F Class. 1/4 MOA wins many benchrest matches. The only way that is possible is if you are cherry picking your best groups, disregarding flyers, etc. In F Class, you have to shoot 20 shots (depending on the course of fire) in a row under 1 MOA to clean the target. That bar is a lot higher than a three shot group. A lot of 1/4 MOA rifles turn out to be 1 1/4 MOA rifles when the shots pile up. The reason I mention this is to keep you from getting discouraged. It's just statistics, not you.
