Note M193, fired through a test fixture, is supposed to do about a minute-of-angle (by average mean radius) at 200 yards.

The spec for the M4 and 855 together as a system (MIL-C-71186) is a 5-inch extreme spread at 100 yards (91.4 Meters).

If you want to dig deeper, goggle the mil specs ref'ed in the info sheets.
But but but I read on here constantly that guys are getting 1 MOA all day with a 4 MOA Red dot and a 16” CL AR!
