S&W AR-15, 16" barrel, shooting good with Brown Bear 52gr HP ammo at 2909fps five shot group at 100yds and the squares are 9/10" not 1" squares. I fired one right after the other as quick as I could acquire my target in the scope. The group at 200yds was about twice this size. The Burris Ballistic Plex mark for 200yds was right on at 200yds and I was sighted in at 3/4 inch high at 100yds.
