Acceptable group size from an AR-15?

[thevalueman]

I would say 2 MOA overall. If it's a quality company rifle 1 MOA.

at least someone here is telling the truth....some here state groups better than my bench rest rifles....

I can’t see the groups, but a quality AR with FMJs should be about 2-3 MOA at 100. Here’s federal 55 FMJ at 100 from a Ruger MPR. My stupid expensive PRS guns with hand loads and/or match production ammo group .5 MOA for 5 shot groups.
