AR Accuracy

[Jingles]

Hopefully an Owner out there that is more versed in AR accuracy than myself. Been a long time since I had to worry about hitting the target with an AR style rifle and then it was an honest to god M16 where targets were marked by person stuck in the butts and targets were raised and lowered.
 Maybe I'm expecting to much from a gas gun but shouldn't an AR at least be able to produce .5 to .75 groups @ 100 yds. Using a factory built rifle have tried loads using various powders and bullet weights.. About ready to say screw it and rig it for spray and pray only

Buy a couple boxes of 69gr Federal GMM and see what it does.

Tell us what kind of groups your getting exactly.
How many rounds through your barrel.
Twist rate.
More info on ammo you have tried ,and I'm sure you'll get more advise.

I don't know that I expect a cheap factory rifle to hit that.

Some of those barrels are pretty cheap.  With a decent barrel this should be doable.  If you can't find a load that this likes, get an 18" $200 barrel and you should be good to go.

Factory rifle is a Stag Retro 15L, yea a lefty
 1:8 twist probably 300 rounds downrange, tried 55 gr  SBT, FMJBT to 65 gr SBT and FMJBT loaded with everything from 1.5 gr below to recommended max in .5 gr increments for each, using sight vice and best group so far has been 1.5 inches @ 100yds  with 62 gr FMJBT(SS109's) 26.5 gr H335 CCI400  have also tried IMR 4835, RE7, IMR 4064 loaded max. using a vortex Diamondback HD 6.5 - 20 X44 
was using the 4 corners in the picture for targets

Im with luvmystang67

Get a better barrel


 Im building an AR pistol right now. 3 places not to skimp. Barrel, BCG an lower kit

[Hilltop123]

Yup, looks to be a minute of center mass

[hunter399]

Maybe bump your charge down to 24-24.5 hodgdon load data says your pretty hot right now.

[hunter399]

I can't say much I'm always over max on my loads too .
But if I'm not getting good loads ,I'll move my powder charge just to see if there is room to improve .I would say start moving your powder charge down if no improvement ,then maybe barrel issue.

Try some Sierra match kings, they always seem to shoot well.   1moa should be attainable.  I have issues shooting at green bullseye if the lighting is off, maybe use a black 1" dot inside?

[Jingles]

I have been basing my loads off the Sierra and Lyman books so did not think I was loading hot compared to what I have my 06 loaded to 58gr 4350 180 gr SBT

[h20hunter]

Imo, I would replace every factory ar trigger I've personally handled.

I'm gonna second this. Run a match 68 or 69.

Should be able to get an inch with that rifle.

I have 3 ARs. Two are for self defense and one for hunting As long as I get "minute of dirtbag" with the two self defense rifles I'm fine. For hunting I bought a Rock River ATH. Guaranteed .75 inch groups but will shoot 3/8 inch groups. My cheaper ARs won't do that regardless of ammo.

[konradcountry]

I think it is reasonable to expect 1 MOA from an off the shelf Stag. They aren't a low end brand.

If you have a bad barrel that kind of sucks because they aren't known for their customer service.

Nothing wrong with a minute of zombie rifle.

If you really want to get into accuracy you probably want a free floated barrel anyways.
