Shooting with iron sights at ranges beyond 100m

I was invited to shoot as a guest of one of the members at the Milo range this go around. I normally shoot indoors here in Calgary except for the odd time plinking or shooting gophers with non restricted. To shoot longer range I usually shoot at the lloydminster gun club when I visit my parents as I have a membership there

Thats where I go too. (Hence the 500M limitation)
I shoot further out on hutterite colonies but then I am using Glass not Irons.

I have never seen one of those before ... I can see how it would help

One was on a 10.3" and the other a 14.5" the longer the sight radius the more difficult these ones are to actually use, Although on the 14.5" the sight post is still about 4.5" from the end of the barrel an you can still get a nice sight picture through it.

I recently received my first AR15 a Smith and Wesson M&P sport 2 and I am wondering how many people shoot longer ranges with iron sights? I know some competions such as service rifle events have a class for iron sights out to I think 600m but I wonder how many actually shoot at those distances regularly? Yesterday I had a chance to shoot at an outdoor range with the AR and was able to hit the gong at 400m about 3 out of 10 tries with the iron sights I had to use the target frame as a reference and had a friend spotting my shots but it seems like its doable with more practice. So how many of you shoot thus way and what tips or hints do you have for the new guy?

Aside from the obvious question of wether or not you can even see your target , you should be able to do it if you know your zero and the associated holdovers.
Standard AR front post is 6moa, if Im not mistaken. So shooting at 400m means it will cover a little more than two feet of your target. Be aware of that.
 
Not all irons are created equal, a quality set of irons can run you as much as a good dot sight but will allow much more accuracy over a set of flip-ups that cost $200.
Unless you really like shooting irons I'd just buy an Aimpoint or other quality optic and then use the cheap flip-ups for a little fun at under 100yds now and then.

You young whipper snappers! Although I don't wear glasses for distance, a slight astigmatism makes it nearly impossible for me to see a "clear" front blade on any of my FA's. By 100 yards the target is small and unsharp enough for me to warrant the purchase of an optic.

I prefer CQB over precision fire so I will be heading in the Red Dot direction and keeping the distances closer to visual acuity. ;)

Be sure to try out any dot sight before purchase, astigmatism will make the dot on some sights go mushy and out of round, some are better than others hence the try before you buy.
 
You know you don't really need to "see" a target to hit it you just need to know where it is with some degree of precision ...just because the sight post covers the target doesn't mean you can't precisely center it if you know where it is and about how big it is ... In fact I seem to remember that the military once taught using the sight post to estimate range based on how much of a known size target it covers i.e. A human torso or vehicle etc

If both rifles have fixed FSB's and carbine length gas systems then the sight radius is identical..
