I can shoot a 2 - 2.5 MOA group from the prone position using irons. With an magnified optic I can shoot sub-MOA all day from a benchrest (Rem 700 PSS). Sub-MOA groups are impossible unless absolutely supported. Involuntary muscle movements make it impossible.
You can expect to shoot 6 MOA standing and 4 MOA from supported prone at 100 yards. That would be from a very competent shooter. Also depends on your eyes and how concentric the dot appears.
An RDS is a combat optic and not made for precision shooting. Go with a magnified optic with a cross-hair reticle for increased precision.
