I went out to the range and practiced a little one handed threat focused shooting with my .45, then I moved my target stand out to 100 Meters and fired this 6.5 inch, 28 round group, with Remington UMC ammo and a DPMS AR. I did it standing up, leaning against the range shelter 4x4" post. I don't have a scope or an optics device on my AR though, only peep sights.
I forgot to mention that the shots were all fired at a fairly rapid pace, 1 to 1.5 seconds between shots.
