What would be a typical 100 yard accuracy for a 16" STD, quality AR fired off the bench with STD sights and generic ammunition ( PMC, S&B etc) ?

1.5-3.5 MOA. Less is better, more is really getting out there for a run of the mill AR.

I can do 7/8 of an inch @ 100 yards with my LMT Defender 2000.

3 MOA is about right with that setup. Of course, everyone on the internet shoots 1 MOA no matter what.

With what kind of ammo? He specifically asked with standard ammo.

Isn't it amazing? I think most of these people don't realize they're actually supposed to shoot a target at 100 yards, not 25 yards. :P

Ammunition and sights are often the determining factor when it comes to a rifle's accuracy. With military surplus ammo and decent optics many chrome lined ar15s will do 1-2MOA. When you start throwing other brands of ammo in there (even different batches of mil-surp) and different sights things change.

unless it's an ak then it 3MOA :p

There should be a formula for determining the actual MOA based on a posters internet MOA :D

It would not apply to chicoredneck because I always shoot MOA or less.

Well yeah, that goes without saying :p
OP, XM193/M855 and their comparable civilian counterparts are generally considered 3 MOA ammo. I believe the military requires 4MOA at most, so that gives you an idea. It is highly unlikely that you will be shooting 1 MOA or less with it, and I would take with a grain of salt those who say they do. Not saying it isn't possible, but that it's unlikely.
Match ammo exists for a reason.

I don't shoot any of the lake city/federal stuff. Too rich for me, but most of the military surplus (IMI)that I have put through my AR15 does better than 4MOA

You're looking at 3-4 MOA, bro. 1 MOA accuracy is what you get with accurized rifles shooting match or handloaded ammunition. You might get lucky and print a 1" 3-shot group every once in a while with a standard frankenstein AR15 shooting walmart ammo, but little do you know that was the best of probably 10 groups.

You would get a better representation of overall accuracy over the course of 1000 rounds fired rather than 3 lucky shots which just happened to pattern 1" within your possible 4 MOA zone.

I suck with iron sights and hovered around 5-6 inches at 100. My buddy shot just under 1 moa all day with my AR. Ammo was PMC.

Gun is a frankenstein. Daly lower/m&p upper. 16" carbine with only 82 rounds fired. A2 sight with Troy buis. Hope this helps, I ha a hard time getting the same info a few years back.

I get around 2.5 MOA or so with PMC. I can just about hit MOA with 75 / 77 gr match loads.

The M16A2 HBAR service rifle (many of which were often run with blanks and a BFA which does not help accuracy) was more than capable of 1 MOA accuracy using standard ball ammo. Even though milspec/standard was supposed to be 2 MOA. That is also with the 3-round burst sear, that was about 8 or 9-pound trigger pull 2 rounds out of every 3.

Even 16" barreled AR-15 rifles are capable of tight groups with a little care in assembly and good ammunition. For example, I just rebuilt a 16" mid-length Cr-lined BCM upper that I bought from another CGer. I was hoping to get an MOA shooter and was willing to put in some effort to get there. Using a scope I shot a 2.5" 5-shot group at 100 yds using PMC ammo. Firing handloads that I developed for another rifle, I shot a 0.5" 5-shot group. Based on prior experience I figure I could shoot a 3" group with that rifle using iron sights and PMC ammo.

im lucky to shoot 5 inch groups with open sights. i have problems with my right eye without magnification. however i have a good friend who was a marine who can put 3 shot groups the size of a snapple cap at 100 yards. he hits 1lb tannerite cans at 400 yards on the first shot guy is great shot

I can shoot .5" groups all day long while doing backflips from a moving Jeep @ 400 yards. And that's with Wolf ammo. If you can't you are a total rookie & need extensive training.
