Yes. That was a single standard issue Colt M4A1 with KAC Rail. 10 shots from 10 different positions at two different distances. A drop in freefloat rail was installed on the same gun and the exact same sequence repeated. Same lot of ammo.
As far as MOA groups size is concerned- it took the 100% hit rate on an 8 inch target from 30 something meters to over 200 on that gun.
Multiple randomly selected M4's were tested in the exact same manor. Shooters ranged from new members still in training to extremely high level competitors.
The gun I shot went from a 100% hit rate (again group size) on an 8 inch target of something like 68 meters, to 290 something meters.
