I have a Colt LE6920 with 1:7 twist in 5.556 and was wondering what groups others are getting out of this rifle! I'm averaging about 1.75" but that's with cheap American eagle ammo. Thanks for info.

At what distance? I may be wrong, but I was under the impression that Mil-Spec requires like 4 MOA.

3-shot or 5-shot?

Most ARs, in my experience, are not sub-MOA guns. If you can get 1.5" 5-shot groups out of it with decent factory ammo, that's about as good as you can reasonably expect. Some factory guns will shoot better than that, and many will shoot worse. But in my experience, that's about the best average group you can expect from 6920-level AR (anything in that same price range with roughly the same features and build quality).

Though I've never shot one of the more expensive models myself, I've heard those can get to MOA or slightly better.

Are you going to buy match grade ammo?

Good question. My post assumed you had some sort of 1-4x scope on there. If you're running open sights, 1.75" is an excellent group.

With a decent scope all my AR's will maintain under MOA. Have not shot the one you speak of though.

I cannot remember shooting any Rock River ARs that would not shoot good ammo under an 1 inch and I have shot a bunch of them.

None of the one I am speaking of are what y'all call "entry " level though.

If you are buying cheap ammo, get the cheap stuff that is 69gr or higher it will do wonders in the 6920.....

it is unrealistic to expect SubMOA/MOA performance from 2moa ammo....... doesn't matter how good the rifle is.......

What type of optics do you have on these?

I had an EOTech on my last Rock River and 1" was about as good as it ever did. Wouldn't consistently do that. But the EOTech is hardly a target shooting scope.

This is a 5 shot group at 50 yards with a 10.5" SBR with a Aimpoint T1 and Lake City 62gr green tip bulk ammo. Was shooting prone off the bag with no rear bag out of the back of my truck. Was a pretty good group besides that one flyer which was me not the gun. With an actual scope and better ammo I could probably tighten it up a lot, but with the 10.5" barrel she really opens up at 100 yards LOL.

My DD m4v1 was sub-moa at 100yds with reloads (75gr bthp/varget) using a Vortex Diamondback 3.5-10x50 and the only other upgrade in the rifle was a Geissele SSA-E trigger.

Guess I should included more information in my post. Leupold vx3 4-12-50 scope 100 yards 5 shot group . I do plan on testing out some match ammo was just curious what to expect from both. I know a 6920 isn't a high dollar custom AR but in my opinion it's not entry level bushmaster either so I was expecting decent groups.

Don't think it's the rifle. I consider the AE 55gn ammo as plinking/training ammo or if you just want to shoot a bunch hogs in a hurry ammo.

I'd try some of that Priv Partisan 75gn ammo linked earlier. You have a 1/7 twist use it. Moving up in weight should help a lot. I'd grab 5-6 of different weights and manufacturers and see what the rifle likes best.

What trigger do you have in it? If it is the factory trigger, get a RRA/LMT 2 stage trigger at a bare minimum. You can find them for around $80. If you want the bees knees, get a Geiselle. You should see your groups improve, even with the same ammo.
