Looking for some direction as to what is reasonable to expect in terms of accuracy for a 16 inch carbine with A2 sites. I just purchased an Olympia (forged receiver) at a bargain basement price and I know it is not one of the big 3 espoused at this site but a build is coming. What does (did) the military expect of the troups in terms of accuracy at say 50 yards,100 yards or even 500 yards as the the manual refers to. I fired this weapon at 25 and 50 yards last night. I looked down range at a 100 yard target and if folks can accurately fire at that range with A2 sites, then I am amazed. Optics are coming with the build, but I want to be at least somewhat proficient with the iron site initially. Thanks for everyone's 2 cents in advance.

In Highpower competition A2 sights are used at 200, 300 and 600 yards quite accurately...
That is the only sight allowed by the rules.

At 75 yards w/ a 20" HBAR I shot a 10 round group the size of my palm (about 4 inches) and that was the first time I've ever used a peep/post style sight.

at 100yds, with good ammo(not milsurp) I can put all the rds in a inch circle, ok with one or two flyers

I have 2 AR15s with A2 sights.

They will both fire 1.1" and 1.2" 3 shot groups at 100 yards with quality ammo.

They will do that consistantly.

The only problem is that my eyes are getting too old for iron sights. When my eyes were younger, I shot better.

The A2 sight is an excellent sight for competition. HP shooters generally have quarter or half minute adjustments and a small aperture.

You may want to use the 300m aperture for finer shooting.

Then prepare to be amazed, as "bubba99" here in this thread: (www.ar15.com/forums/topic.html?b=3&f=118&t=249948), shoots groups "all day long" using iron sights that most of us would be happy to shoot using scoped AR15s.

That's of course provided ya buy into his BS.

The guns are accurate enough in a trained shooters hands to engage full silholuttes out to 600m. Last Friday evening took a 300m standing off hand shot with my M16A2 and rang steel. Just have to remember your fundmentals and hold steady.

I was struggling to hold 4 minutes last weekend. I don't shoot off the bench ever because there are no benches in any real world shooting scenario. But I still like to keep 5 out of 5 shots in a 4 inch by 4 inch square at 100 yards.

That's good shooting, markm. My offhand target of choice is a whole 8.5x11 sheet of paper.

It depends on what you mean by "accurate". The military -- the Army, anyways -- says that a 4cm group at 25m is acceptable for a 300m battle zero. That's a 16" group at 328 yards, which they consider enough to hit an enemy soldier. At those distances for that type of shooting you're aiming center of mass on a silhouette, not at a little bullseye. At 300m, the silhouette is about 1/2 the width of the front sight post.

I zero my 20" A2 like that, and I have no problem hitting a man sized target at 300 yards although my groups are sometimes 10 - 12", even from the prone. At 100 yards, prone, sometimes I'll squeeze one a tad under 2". I'll make off with hree inches (prone), more often, and 6" offhand.

Now of course, the rifle is capable of doing better than that, especially better than my longer range shooting and even with military ball rounds (let alone match ammo), but many shooters are nowhere near as accurate as their AR.
