AR-15 accuracy

    Search feature is not working for me at the moment so I will just ask. What kind of accuracy should be expected from a standard ar-15 with a 16" barrel? Bushmaster vs. RRA vs. Stag?

    RRA says that their "entry tactical" will shoot MOA at 100yards which is plenty accurate for me. But then I hear stories of a standard bushmaster shooting 4-5 MOA at 100yards. All insight is welcome.

    First, in measuring accuracy by MOA, you need to know:

    Number of rounds in the group (5 minimum, 10 preferable)
    Type of ammunition (most cheap FMJ ammo is only 3-4MOA from a top notch barrel)
    Shooting position
    What the shooter can do at their best

    Pretty much any of the rifles you mention has more inherent mechanical accuracy than most shooters are capable of appreciating. I suspect all of them are capable of 1-1.5MOA five round groups at 100yds with match-grade ammo that they like (you may have to try a few to find what it likes best).

    There's a poster on another board that I visit that was complaining about only getting 4 moa out of his Bushmaster M4gery. He admitted that he's only shot Wolf ammo through it and didn't want to spring for some premium match ammo to get a better idea of what his rifle was capable of.

    My analogy about buying a high end sports car then being too cheap to put anything but the lowest grade gasoline in the tank comes into play...

    My M4gery (Smith and Wesson) doesn't have sights that tend to give great bench rest groups.

    It's setup for getting fast hits on moving targets.

    With the EOTECH, from the bench, It's done just under an inch at 50 yards with Remington 55gr soft points.

    Call that 2MOA and get on with it.

    Good enough for a combat rifle.

    From my Smith & Wesson M&P 15...

    10 shots at 100 yards...iron sights...with a scope this group would shrink. These were handloads using 55 grain FMJ-BT bullets


    10 shots at 200 yards...


    10 shots at 600 yards, iron sights...4 missed the paper, the wind was blowing pretty hard that day...the quarter is roughly the center of the group. The paper was taped to a Cadillac hood...which was my POA...I cant see a sheet of paper at 600 yards. I fired 1 shot, then my son placed the paper over the bullet hole, then I shot the group using the same sight picture...

    that's pretty damn accurate for using just iron sights, nice job. I'm picking up my stag tomorrow so hopefully it's close to that accuracy. unfortunately I won't be able to go to the range for maybe a week.

    wow if i could shoot like that at 100 yards i wouldn't need optics... very impressive.

    You can...it just takes a few years of practice. I grew up shooting iron sights (couldn't afford a scope)...by necessity I learned to use them. Its all about sight picture and being familiar with your ammo's trajectory. (not really that simple...but to put it in a nutshell)

    Wow....I have 20/15 vision and cannot even see that at 100 yards.

    That group, made with a S&W MP (non-match grade barrel) rivals the performance of match-grade barrels, but was also shot iron sights?

    I'd have to be there to believe it.

    You mean that you don't take everything you read on the internetz at face value either.

    I have the RRA Entry Tactical. You won't be dissapointed if using quality ammo.

    I have a Bushmaster M4. I've only shot my own loads, which are slightly lighter than max with a 55g soft point. With a cheap Leapers 6x scope I can shoot an average 1.25" groups at 100yds. I was originally hoping for 2.5" or better, so I'm plenty happy with this upper.

    Mine is not chrome lined, does not have M4 ramps and the ramps are not polished, I only use PMags, and it's absolutely reliable.

    Dont Tread On Me...if you were here I'd gladly prove it to you. I'm not your "average Joe" shooter...but since you don't believe me I wont explain any further.

    Not to make this thread take a fork in the road, however, ridgerunner is to be congratulated for a job well done. I have seen and I have done with iron sights groups that others can't do with scopes. So don't kid yourselves into thinking that just because you can't shoot iron sights that everyone else is likewise unable. As stated it's all about sight picture, knowing your set-up and repeatability. Having a trained eye to focus at the correct spot at the correct time is somewhat the trick. It takes practice. Picking an arbitrary spot that allows visual cues can help also.
    This is a pic of a group I shot at 100 yrds. off the bench with my national match Swede, CG63, and iron sights, 6 rds. Also some iron sights are better than others. These iron sights are like optics without the optics.
    Is ridgerunner's pictured group his best? Perhaps. I know I don't take the time to photograph crappy groups.

    So far, with this rifle it is...I've only had it a few weeks.

    I checked a friend's DPMS 16" upper with 2 types of ammo he's interested in on Monday. Target was at 50 yards, 2 groups on left were 62gr PPU, 2 groups on right were 75gr OTM from PPU. Point of aim was the center bottom edge of the 3" post-it, grid is 1". Rifle had YHM iron sights and I wasn't real happy with the light, but if you shoot in OR in the winter you take what you can get. BSW

    edited to add: Carbine was sandbagged and has a 1/7 barrel. Perma-mounted FH and the crown looks like 7 miles of bad road. BSW
