So, I finally got my AR15 sighted in semi-properly at 50m and decided to give it a shot at 100. I sighted it in using the improved battle sight with a 50m/200m zero.

This is what I ended up with, I think my sights might be a little high still, but I am fairly pleased considering I haven't shot an AR very much, and certainly not with iron sights.

What do you guys think?

Hard to tell one group from the next, should have circled them

ohhh.., burn. :D

It was all one group, fired the rounds I had left in the mag, under a fairly quick pace. The iron sights are much trickier than a scope, picking out the target at 100m will take some getting used to.
 
Maybe your eyes are better than mine, but I can't see orange worth s%$t at 100yds. Get yourself a large solid black bull. You'll be amazed how much easier it is to shoot with irons.
 
So top of post was at the center of the target?..

Gun might be zeroed for 6 oclock hold?... so your shooting high.. I think?

Anyone else care to help me out here?
 
Looks as if the centre of the group is 4 1/2" above point of aim. Zeroed for a lot further than 100y. Unscrew the front sight to lower the group.

would still be a bit high, got a peep in the back? if so, its shooting high.
A slow time shoot in at 25 will confirm , or even 50 m, those front's are screw in are they not?
I have shot the AR , with horid results, that spring sks type recoil takes some getting use to.:D
Looks like the tgt is upside down? Is that they way it was mounted?
 
Before you play with the sights try and check to confirm the handle sight itself is on correctly and tightly.

While you could adjust the handle sight for elevation, you can also try using the other aperture on the rear sight as well. I like using the smaller aperture, it really helps for me.

Finally the front sight can be turned to lower the point of aim. Push the pin in and rotate to suit.

Nothing wrong with using iron sights. I prefer them.
 
The centre of your group is 6" high, your rifle is not really zeroe'd for 6 oclock, depress the plunger on the front sight and turn it counter clockwise as you are loooking down at it. I would suggest about 5 clicks to start and see were that puts you. What position where you in? If you were prone and slung up, do a check on your breathing, that would account for the up and down stringing you seem to be doing. Finally, hold your breath as you squeeze the trigger. Send me a pm with your email in it and I will send you a copy of the U.S. Army marksmanship mannual, it is very good!

I have read parts of the US Army marksmenship manual and choose to sight my rifle in using the improved battle sight technique ( ie, 50m/200m zero). I would of expected a grouping roughly 2 inches high at 100 yards suggesting to me that the sights are still a little high.

I might make it out again tonight just to see, I will post my 50m grouping if I do. I think I need to drop it by 2 clicks on the front sight to have a bang on zero at 50m (well, as bang on as I can get it). I'll try modifying the target as well, the orange is a little difficult to see, nothing to bad, but it could probably be better.
 
So, I got out again tonight, shot another 10 shot group after some adjustments. I think this is pretty close to where I want it sighted in.

I had at least one definite flyer, but I think there is some slight signs of improvement. The difficult part is seeing the target beyond the front sight, as the front sight takes up nearly the entire target at 100 yards (at least width wise)

I'll keep practicing, so far, I really love shooting this gun. :)

Have you guys got any tips for shooting through iron sights? Ideally, I'd like to get down to a 1 or 2" group....if possible.

Are you using the small, or big aperture when you are shooting at 100? What ammo are you using, if it is 55 grain factory stuff, that group would seem pretty normal.

If I am shooting groups with my AR, I use the small aperture, and mine likes the 62 grain Remmy stuff.

Those are all "A" zone hits for IPSC and IDPA

Were all shot with the small aperature with 55 gr FMJs. I was thinking the same thing about the A zone hits, but for longer shots out to 200 yards, or for shooting some of the small poppers they have in Michigan, I might be in trouble. :p
 
I assume the barrel is 1/9 twist........you will probably get better results with 62 grain ammo......also, the barrel is pretty new isn't it? Mine tightened up after 200 rounds or so. The front sight on an AR isn't meant for pinpoint accuracy either. If you can drop it down to a 2" group, you would be laughing.

Good to know :)

Is the 62 gr available in bulk anywhere? I think I will be shooting the 55s for a little while, but its good to think ahead. yes the barrel is new, seen about 40-60 rounds.
