I really don't know much about shooting rifles but I laser bore sighted the scope and I was only off 2" low and 2" right. I still could only manage 4" groups. It was cold. Only shot 30 rounds. I think I may have to move the scope. I had a hard time getting a good look at the target.

That rifle should perform much better than that even without a scope.
That scope is probably a bit large for 50 yd shooting, and I would try moving out to 100 yds to see how it groups. If you don't shoot rifles much and it is cold, that will certainly affect group size. It also looks like the scope is maybe mounted a little too far forward, which would create an eye relief issue. Just a couple of thoughts, hope this helps.
With my service rifle I put the ACOG eyepiece right up against the bridge of my issued glasses (the ugly turtleshell BCG ones). The recoil from .223 isn't bad so I would only start to get a headache after 30 rounds or so... Probably have brain damage now.
Hold it like me here in some town that I will never know the name of.
You may want to try a riser mount to get that scope up a little.
I bet your having a hard time looking through that scope being mounted as low as it is. Your probably not getting a very good cheek weld either.
4" at 50 yds? With a scope that big? Please tell me you were shooting offhand in a 75mph wind and your teeth were chattering from the cold...[B)]

i was thinking similar but not as exaggerated
bullet weight, and twist rate rated on the barrel is important, but if your getting 4moa at 50 yards i would say something else is involved, look at the twist rate 1:9 you should be ok with that 55grn, fork out for a few boxes of good ammo, and if possible get a second shooter to shoot it from a rest
honestly ar's notoriously don't like steel cased ammo but that's a feeding issue

1moa is roughly equal to 1" @ 100yds. If he's getting 4" @ 50yds, then he's shooting around 8moa, not 4. I can consistently shoot around 2 moa with my armalite, and I do not consider myself to be an expert shooter. I shoot a lot, and I shoot well. But I do not think I can shoot any better than many other shooters. I think there is a definite problem here with the rifle, ammo, scope, scope mount, rest, shooting conditions, or a combination of several or all of these things. I cannot tell from the photos what manufacturer produced this rifle, but I would expect far better performance even from the lowest ranking manufacturer.
I would think some different ammo and/or a different shooter could help narrow down the problem. If it can be determined that the problem is the shooter and not the rifle, then that would be a good thing. Learning and practice are much cheaper than parts and repairs.
The OP has said they are a new shooter (at least to rifles) and that it was cold, and it was difficult to see the target through the scope....
With that scope, you should be able to see just about anything! [:D] Move it, adjust it, and play with it. There's no point having a scope mounted where it's unusable. Figure out where it needs to be for YOU. You should be able to find a pretty comfortable location. As already suggested, you may need to try some higher rings to bring it up to your eye with the proper cheek weld. And you DEFINITELY need higher rings if the scope is touching the handguard at all.
Spend the money on at least one GOOD box of ammo. You won't need much to tell you if it's gonna shoot better than the ammo you're currently using.
We don't know where you got the rifle. If you bought it new, you may disregard this. If you got it used, assume the previous owner never properly cleaned it. Clean the barrel. Use a good copper solvent like sweets to make sure all of the copper fouling is out. This is not a bad idea even if you did buy the rifle new. Copper fouling will kill accuracy regardless of what kind of ammo you're shooting.
If it's cold enough that you're shivering and can't hold still, then you might as well enjoy shooting it, but wait until it's warm enough to sit still on the bench before trying accuracy tests.
Most AR's come with either a 1:9 or a 1:7 twist. The faster 1:7 twist is designed to stabilize the heavier bullets like 62 grainers and heavier. For 55 grain bullets and lighter, the 1:9 is great. Again, as previously mentioned, the twist rate should be stamped on the barrel. If not, it's pretty easy to find out for yourself. There are several youtube videos available to show you how if you don't already know.
you cant hardly sight a rifle with a mag that hits the table. I suggest using the 20, or a 10 is even better or getting soome sand bags that stack high enought to rest the gun on it's own.
then all you need to do is adjust a little and squeeze the trigger. You have to set aside the fact it's cold outside, or the fact you are cold. You can do it, forget everything around you for a split second when you become a rock and the only part of your body that can move is your trigger finger.
and one last thing, no disrespect. But is that an rimfire scope?

That's what I was thinking... Get a Burris P.E.P.R. mount or a Larue LT104. Either of those will get the scope up where it'll line up with your eye and get it off the front handguard if it's touching there.

yes the standard meaning of "moa" is at 100 yards, i should have know better than to post the slightest of error

Im not worried about your error. Crap happens to us all. I was making the point that there is reason to be concerned with what the rifle is actually shooting.
