Finally got to the range with my Ruger 556 to zero my Magpul MBUS in. At 100yrds, using a rest, I was able to put 10 7 in a 3.25 in group, 11 8 with a flyer that put the group out to 4.1 or so.
Ammo was PMC Bronze 223A 55gr FMJ-BT. I was not trying for super small group, just getting it on the paper. It was windy as all get out and cold. I know it won't win no match or anything but... is it acceptable?? ETA: Picture / and I can't count

I wasn't jerking/slapping the trigger... the factory trigger does leave a little to to desired... |

Acceptable accuracy is a personal decision. Exactly. I would not be happy with a 100 yd. group that size but you did say it was windy, and windy with a .223 means bullet dispersion will be greater than with bigger calibers/bullets. Try it again some day when the wind is down. My S&W M&P 15 (5.45X39) shoots 4" X 6" groups at 300 yds. with Russian surplus. It wasn't windy, just kind of damp/misty. I'm happy with that one. To be honest, I've not shot any of the other AR15's at anything past 25 yds. But the good ones will shoot dime sized groups for 5 to 10 rounds at 25 yds. I need to shoot some of them farther out. |

Acceptable to Ruger. My Dad sent a Model-77 7mm Mag. back to them saying it wouldn't group any brand of bullet better than 4" at 100yds. They sent rifle back saying it was within their acceptable accuracy standards. He sold it off saying he would never buy another Ruger product.
Try it again on a calm day. |

I have owned 7 ARs and find 3-4 inches with irons to be normal at that distance. I'm not a tier 1 winged ninja salad shooter like the other guys here, though. If you can't put 50 rounds in a penny from a moving MRAP you ain't shit. pfftt....try thru a rolling 1/4 inch washer..amatuers... 
read siggy...

an retired army dude taught me a trick that helped me.. he said to sight the front sight wings where they touch the sides of the back ring vs. lining them up in the middle and trying to get the same spacing on each side. this cuts down on your field of vision when looking thru back sight but it helped my group greatly. |

4 MOA is what you need for Appleseed Rifleman. At what minimum distance? MOA is an angular measurement. Distance is irrelevant. For example-1MOA= 1inch @ 100 yards, 2 inches @ 200 yards, 3 inches @ 300 yards, 1/2 inch@50 yards, 1/4 inch @25 yards etc., ad infinitum... |

I'm going to go against the grain and say I wouldn't be satisfied with that. With a new rifle I want to see exactly how tight the barrel is capable of shooting. You would have to put it on a BR rifle for that. I have a $300 muzzle loader that easily shoots 1 inch groups at 100. It's no BR rifle. Like someone else stated acceptable accuracy is a matter of opinion and after a 4 + inch group I'm trying to figure out whats wrong. |

You said you wanted to see exactly what the barrel was capable of, not how still you can hold it with your hands. |

4 MOA with irons, cheap ammo, and a rack grade rifle is fine... if shooting from an unsupported field position.
From the bench, slow fire, which removes much human error, I'd prefer to see a significantly tighter group, more like ~2 MOA. The problem with that group is that it is not very consistent or circular in shape. It is slanted low-left. Assuming you are a right handed shooter, that could be "heeling" the rifle which is basically pushing forward a bit with your firing hand just as the shot goes off. It could also be pushing the shoulder forward in anticipation of recoil, too. Try ball & dummy drills and see if the group gets more consistent and tighter. I would not actually make any sight adjustments with that target, especially with the "flyer;" unless you called it bad when you fired, it might be more heeling or bucking going on. If I couldn't shoot another group and had to make sight adjustments based on that target, I might go 1.5 MOA right and 1 MOA up (assuming you want a 100 yard zero... :-\), but I'd much prefer to get a more consistent group first. |
| Three-ish inch groups with irons in less than ideal conditions is about all the ammo/barrel/trigger was designed to do. I've been shooting all my life and I'm fine with that off a rest for a stock AR with iron sights. You now know that the rifle/ammo combo will do pretty much what is was designed to. |
