    I dont think I'm going to be a marksman with these iron sights. Question? Is this acceptable shooting? AND Do you think I should go ONE CLICK down on my front post based on the 10 shot distribution? I was just trying to aim at the center of the target but at 100 yards I cant see the bullseye let alone be pinpoint accurate at that distance with open sights. Any advice would be helpful.

    I am guessing from the end of the barrel in the pic you are shooting an AR. I know people that could not hit that piece of paper at all from 100 yards with open sights. When you see people shooting 2 inch groups at distances like that they are using scopes and sand bags. When I was in the army I was suprised how many people couldn't hit a full sized sillouhette at that range.

    You would fit right in with the shooters I know. If you plan on shooting the next olypics you need more practice. Otherwise you look fine to me.

    First move it in to 50 yards and start there shooting a lot at 50 yard and get to a point where you can create decent groups weather they are 1" or 6". From the looks of that target you are all over the place I wouldn't move anything until you get a little better at sighting. You may be jerking the trigger who knows take your time and if you need to shoot 1 or 2 shots and then close your eyes for a short time to rest them then open and shoot 1 or 2 more times. Work on your marksmanship before adjusting your sights all that much.

    I'm with tango, there isn't a distinct group and until you get a grouping you really don't know how to adjust your sights.

    Also, adjusting your front sight is a HUGE adjustment. Once you get a good group the front sight should only be changed when a serious move is needed. If you move your front sight down that will raise your impact point, move the rear sight down and you'll lower it.

    100 yds open sights

    Shooting a cmmg bargain bin 16" midlength(double star lower) with fiocchi 55 gr fmj. The other is a bargain bin 18" rifle lenght with a cheap red dot that my 14 year old is learning to shoot. I think I'll go back to the 50 yard line and try grouping again. If trigger pull was an issue I think I would be PULLING RIGHT being that I am a right handed shooter.....there wasn't mush more than 4" of variance at 100yds so I am pleased with that. Has anyone tried filing the front post down to a POINT?....at least then the thing wouldn't be so wide at the top @ 100. Thanks for the comments made and any future ones received. Its great I can go somewhere to get an array of seasoned advice. My advice: SHOOT SOME AMMO but HOARD SOME TOO!

    One thing I've found, when shooting groups with iron sights, it helps to have a consistent aiming point so you can get repeatable sight alignment.
    At 100yards I would like to have a target with a large black center at least 6" diameter, 10" would be even better to get a repeatable 6 o'clock sight picture.
    you can go buy targets or even spray paint a paper plate black.

    Then adjust your sights to give your groups the elevation you desire up from the bottom edge of the target.

    taken from:
    Zero and M16A2 Rifle (ArmyStudyGuide.com)

    go there for the images with text on how a basic battle sight is done for a standard m16 series. this might give you better idea. open sights are more for combat rather than competition. with proper technique a good rifle person can give scope users some competition at shorter ranges

    I'm with Tango that you should start a little closer. I went through the same thing with my Bargan Bin Double Star (Model Star 15) rifle. After I got sopem, first hand trigger time with my rifle I got to where I could put a good group at 100 pretty easy. I have since put a 6x scope on ot nad shoot out to 200-250 all the time and keep them respectable (6") even on a windy day.:)

    Thanks gatekeeper!

    I'll spray paint a paper plate black and stick it against a white background and do the 6'oclock hold to see where I'm grouping. I'll give a range report in a few weeks to report on any progress. I go through this everytime I get a different shooting iron but my philosophy is that I need to be able to shoot the rifle proficiently before putting optics on it....what if the optics fail? I had a really hard similar transition going from the 870/1100 configuration to the over under configuration quail hunting. I stuck with it and didn't give up and now I can hang with the best of the best in varying quick point situations. It kept me from switching guns or simply giving up and buying something else which is what a lot of people do while blameing it on the gun without giving it an honest try. The only other military type weapon I have is an sks but it was a peice of cake with the sights....this ar platform is entirely different and I LIKE it but I've got some practicing to do. I won't give up.

    Sight in your AR-15 at exactly 25 meters with 55 grain FMJ ammunition. Use this target:

    I shoot ½ size NRA official 100 yard military type targets that I print on my computer, for testing ammo and shooting 22LR out of my AR. At 50 yards.
    The 100 yard targets have a 6 ¼ inch black center, same as the gun clubs use for CMP shoots. The ones I print for 50 yards have a 2 ¾ inch center(as close to ½ size that I could get it).
    What ever the spread is at 50 yards will be double at 100 yards and 4 times at 200 yards. The CMP 200 yard targets are twice the size as the 100 yard targets.
    About the best I could do at 100 yards would be a 2 inch spread, and not always that close.
    Read what the military manuals have to say. One thing they say is start by putting your nose against the charging handel.

    You could also try using one of those stick on Orange pasties for the center of your target. They are often visible at that distance and have really helped me hold to the same common aim point from shot to shot, vs. a black blob.

    I need to ask, and no I have not read all the responses, so if it has been asked take me hunting! :) Is your AR an A2 sight? If so is the rear sight set at 8/3? What sights are you using? At 100 if you are shooting high you need to raise the front sight. My DCM A2 shoots tiny little groups at 100. JP

    JPATT: I have a midwest industries rear sight and the standard triangle on the front. I think I will leave it as is and try the zeroing target at 25 yds and then try again at fifty. I think I am close but I want to do better!!!...and be proficient on paper at 100 to enable me to hit anything of size at 200-250. JPATT, I'll take you hunting for quail anytime in missouri if you will take me grouse hunting in NH!!!! We will leave the AR's in the truck!

    Gatekeeper's got it right. Get some SR-1 target repair centers and go to work on a bull you can see. The idea is that the aiming black is the same width as your front sight post, so you can get a repeatable aim going. You can order them at the following link. Get the SR-1C.
