| 16" J&T kit has about 500 rounds through it. It seems to be pretty consistant now. I'm getting about 1/2" to 1" , 3 round groups, but I'm having trouble with sight picture. Using a 100 yd rifle target, the front sight (square A2) seems to be covering up too much real estate on the target. It bothers me a lot. Qustion is, should I be aiming with both eyes open? Will this help? I'm not used to doing it that way, but I guess I could re-learn if I need to. Any tips? |

"is your rifle sight in so it is shooting high? and are you using the sights differently to ompensate". I don't think so. I am trying to put the top of the front sight in the middle of the rear sight, and then lining up on the center of the target, but I get this "edge" effect around the top of the front sight that obstructs the center of the target. Maybe it's my glasses. I havent tried with contacts yet, but it may be a while since I don't have a current perscription. |
For one thing don't "try" to center the front post in the rear aperture, just let nature take it course and your eye will naturally center the front post as your eye will go for the point that has the most light, which is the center of the rear sight. I would give the "both eyes open" style a try. That will help you see more of the target since you'll be seeing it with your other eye as well as the sight eye. You might also try Lowering your POA as compared to your POI. Set up the sights so you'll be hitting 3" high at 100yrds, that way you'll see more of what you're aiming at. That way if you're shooting milk jugs you'd aim at the base of the jug to get a center hit. Also, have you thought about trying some optics on your AR, maybe a scope or dot sight.

| TNFrank, thanks for the suggestions. I will give then a try. Yes, I would like to go the ACOG route, but I just don't have the money right now, and I would like to be proficient with the irons before going optic anyway. I was hoping to be able to get close to "expert" before making any changes, but realistically it may not be in the cards for me, without laser eye surgery. I will just do my best with the irons until I hit my ultimate limit. At that point I will revisit the ACOGs. |
| Second what others have said and stay on that front sight--be semi-conscious about sight alignment and keeping the front sight centered in the rear, but stay focused on the front sight. Your eye will naturally try to make the sight alignment happen anyway. Try a 6 oclock hold. |
ACOGs are expensive. You might check into an EOTech or an AimPoint or even a Trijicon Reflex II. All are good optics, personally, I'm going to get a Wilson Combat Lo-Mount for the A3 upper that I'm building and mount a Weaver 1-3x on it. That'll give me the option of 1x for CQB or 3x for longer shots while hunting or shooting targets. Plus, the whole package will only run about $230 bucks and I won't need batteries either. Just some more food for thought. Talk to ya' later.

If it is taking up too much space in the horizontal plane, I would try a thinner front sight post. If it is taking up too much space in the vertical plane, then you need to adjust the front sight post down (from what you said, I don't think this is the problem. You could also try using the larger aperture to let you see more "real estate" |
| I believe the "correct" way to use iron sight is pumkin-on-post routine, meaning the target should sits on top of the sight post. A narrower sight post would help at longer ranges (beyond 100 yds.) but at 100 yds range, the military std. width post should be fine. |
That may help. Most people think that the smaller the aperture the more accurate but that's not the case. Your eye will focuse in the middle of the aperture no matter how large or small it is. The only reason that target shooters use a smaller aperture is to cut out distractions and act as a lens to clear things up a bit if you have poor eyesight, it has nothing to do with being more accurate. |
Wow. Some great ideas here. I'll have to get back out to the range as soon as possible, and give it another SHOT.  Some of your suggestions are making me think that I might have the front post a little too high after all. I'll also go back down to the bigger rear aperature. I think it's making me strain to get focused right. Thanks for the suggestions guys. I'll post an update when I get a chance.

Sounds good. I really hate the small apertures. I always use the large one unless the distance is pretty large. I replaced the A1 apertures with A2s on all of my A1 uppers. |
Get "national match" front and rear sights. Just beware "fake" NM rear A2 sights. Genuine NM rear sights will have either 1/4x1/4 moa or 1/2x1/2 moa adjustments, not just the smaller aperture. There are a few vendors out there just swapping out standard A2 rear sights with the smaller apertures and calling them "National Match", and charging an arm and leg. The national match front sight post is much thinner than the standard A2 post. here is one place to get them: Armalite NM parts |
