The groups are pretty erratic. I have shot it off a bench with a grip-pod and a rear sight that I guess is a backup sight for the military. I have also used a Burris AR-332 3x prism sight with results that are not much better. I worked up my loads from 22.7gr IMR4895 with no real change in accuracy. I may need to try a better rear sight since the one I have seems a bit cheap and as the name implies a "backup" sight. It does have a flash suppressor that came with the upper. I have looked at it to see any bullet strikes, and there is no apparent problem there. It is the standard M4 type. I think it is removable, I just don't know much about the AR platform or how to tell if it is removable. My front sight isn't adjusted too far out. It is flush with the sight base. I torqued my rear sight to the flat-top to 20in lbs. I do hit what I aim at though. I was always told that AR's are inherently more accurate than say an M1A or Garand. And since Ar's are taking over service rifle, maybe that is true. I'm just not seeing it. Thanks for all the replies.

I don't know where Winsor is but if you want to bring it by, I will take a look at it for you. I can probably tell you whats wrong with it. No charge.

I hope you don't take this wrong but since I don't know your experience I need to ask...
When you are using the iron sights where is your eye focused (rear sight, front sight or target)?
When you are using the scope where is your eye focused (reticle or target)?
Any bucking or flinching when you fire, how is you breathing?

RARGUNS, Windsor is located just south of Fort Collins. Thanks, I may take you up on that offer. Although I have no idea where you are located.
esaabye, I am very experienced with scopes (I work for Burris in repair), and I'm very good with iron sights. 400 yards with an M1A or Garand no problem. And I compete regularly in service rifle and defensive pistol. I placed 1st at the Frozen Chosin last weekend. I focus on the front sight or with a scope, the reticle. My breathing needs a little work, but I am getting the hang of it. Bucking and flinching are a non issue. My trigger on the AR is the crappy single stage DPMS (lots of creep). I'm really not a fan of it since I'm used to the military two stage, and a 4 1/2 lb pull.

I did not mean any offense. At this point you have eliminated the shooter, the sights and the ammo so you are left with the barrel. I don;t see anything else.

We are in Castle Rock. It's about an hour and 15 minutes.

No offense taken esaaybe.
And castle Rock is a little far for me but it still is an option.

Well I took the rifle out to the range today with a known good 3x9 scope and tried my best to print a good group from a bi-pod. I tried several factory loads including PMC 55gr fmj, Hornady 55gr V-max, Fiocchi 62 gr fmj, Lake City 55gr, green tip, and ADCOM M855. All cartridges performed roughly the same. The best group I was able to shoot was just under 5 inches. I have e-mailed DPMS with this issue and hopefully they will help me out even though I lost my reciept. Maybe they know what the issue might be or have me send it in for evaluation. I have never dealt with DPMS and don't know how good their customer service is. Maybe some of you could chime in. I know the general concensus is that the barrel has a problem and you all may be right. I just figure I would let DPMS figure it out before I invest any more money in the rifle.
Here is one group of 20 rounds slow fire using PMC Bronze 55gr fmj. I was absolutely frustrated as the other groups looked the about the same. This was shot at 100 yards. and it was very calm today, just cold.

Wow! Barring any human error, I would say something is wrong with the barrel. Look at the bright side, you can shoot around corners with that thing. If DPMS doesn't figure it out, call me. I have an extra barrel, I'll help you out.
