Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
I would be happy with 3 moa. Mine is more like 6. A new upper is not in the cards. What is the average muzzle velocity for most factory loads? I am loading to 3000fps according to Hornady's book. How about those free floating hand guards? Do they work? And what barrel would you suggest? I want to keep the same profile barrel.
Accuracy is a subjective thing. Please describe a bit better. Are you grouping ok or are you getting erratic flyers?
Is it hitting what you are aiming at or are you having to "Kentucky Windage" it?
It will help us figure out if it is a mechanical problem or an ammo issue.
COCCW- I have been led to believe that the 1/9 is more of a "all around" twist rate and that it will produce better results with lighter grain weights. The quicker 1/7 favors a heavier grain weight.
Personally I havent noticed much of a difference but I am not an accuracy nut with my AR's either.
If I am incorrect can you refer me to some info?

If you are at six minutes then floating will not help much. It does help if you tend to sling up hard but you should be able to see 2-3 minutes off a bench without a problem.
To see 6 inches I would start looking at my sights. If you have raised your front post to far it can wiggle. Is the sight base tight? If you have a detachable handle it might be loose as well. If scoped, how is the mount? Cheap scopes/reddots can move with recoil.
Are your holding the same? I have seen issues with red dot users with larg moa dots having a hard time with consistancy.
A 1/9 should shoot 50gr - 69gr without a problem. The Fed bulk 55 shoots 1.5 for me at 3300 ft/sec, the American Tac is about the same. Same rifle with 69gr SMK at 2700 ft/sec does .75 inch or so. The bulk stuff will have a flyer every now and then but should group well overall.
You are correct, I had it backwards. (Long day & 2 sick kids.....) Good thing I just have the mfg build what I need...Originally Posted by BPTactical
Whew!-Thought I steered folks wrong. Thank You
Hope the kids feel better before Satan Claws comes

Before replacing the barrel, does it have a comp or flash supressor?
Can you remove it? It could be a slightly bent comp or supressor deflecting the exit gases resulting in instability of the bullet exiting the bore similar to a nicked up barrel crown.
If it doesn't can you closely check the barrel crown? Any nick could be the culprit.
These are some simple causes of poor accuracy that can be easily and cheaply fixed.
I say lets all remove the warning labels and let nature take its course.
Not to knock your reloading practices or anything but did you work up a load or did you just start at 3000 FPS? Every single rifle is different and therefore likes different loads. Start at or below 10% of max and work your way up. Shoot groups of each and see what gets you the best accuracy.
There are a lot of things that can cause it to shoot inaccurate. Too many for me to speculate.
If you do end up wanting a new barrel, I would suggest a Black Hole Weaponry polygonal barrel. They are available in any profile, any length and match grade is also available. These shoot sub MOA and we have been doing a lot of builds with them with no complaints. And as aways, forum members get a discount.
