I just sighted in my new Colt 6920 with YHM flip up sights. I was told to zero it at my indoor 25 yard range range to be about 1 inch low at 25 yards and that would put me close to being on at 100 yards. How does the elevation look for the distance I was shooting at? The red dot is 1 inch. The 1st from the left is 7 yards then 10 yards and 10 again, then 15 yards with a 3 inch circle target, and finally 25 yards with a little larger red target. The ammo was Aguila 223, Xm193 and Wal-Mart Federal 223 all in 55 gr. I'm also aiming with a 6 O'clock hold or putting the top of the front sight on the bottom edge of the red circles so they sit on top of the front sight post Thanks for any advice!
