question regarding small aperture on AR sights

I know large aperture is for 0-200...but is it ok to use the small aperture at any range? I feel like it gives me more precision during a sight in...even at 25-50 yds...?
 
You can use the small aperture for any distance you like, the larger aperture is for faster target acquisition at shorter distances, that's always what I was taught. the smaller aperture will help with your accuracy at shorter distances.
 
The small aperture is for accurate shooting at all ranges. Get comfortable with this aperture and it will serve you well. The large aperture is useful in CQB scenarios that involve short ranges and quick acquisition. The large aperture is also used primarily in low light conditions.
 
What he said... ^^^

I never use the large aperture, the only time I flip it up is when I let someone else shoot my AR who doesn't know to put their nose on the charging handle. A lot of the new shooters ask "Why can't I see anything through the rear sight?" I explain the nose should touch the charging handle, then they tell me their neck doesn't bend like that. :confused:

Competitions shooters often use even smaller apertures.
 
Just be aware that the standard A2 aperture will shoot to two different points of impact between the large and small apertures, if you want it to shoot to the same POI, get a same plane aperture
 
What roklok said, as originally designed, the small aperture is zeroed to 300m (or whatever height the elevation wheel is set at) when the large aperture is zeroed to 0-200m. As a result, you will see a change in point of impact when you flip between apertures unless you have a same plane aperture.
 
Wanna hear how cool the M-16 was?

The holes of the aperatures are centered differently for windage too. They are corrected for 1/4 of a turn around the screw the sight is on when you flip it -- the threads move the sight horizontally an imperceptable bit.
 
will make zeroing easier

I am going to get He-- for this, BUT you can not zero peep sights, you can adjust them, but a zero will depend on the placement of your head in relation to the sight and the front post. Since the top of the front post should be right in the middle of the opening of the peep sight, each shooter will have a slightly different sight picture depending on how far back on the stock and to what angle their head is resting on the stock. This will effect point of impact.

That is why the military is spending a lot of money equiping their rifles with Accog's and EOtech's. It is cheaper to give their men $900 sights than to train them the proper way of holding/sighting their rifles. Some do very well with peep sights, but it does take pratice, pratice and more pratice and a consistant placement of the head on the stock. It is just easier to to put a red dot on and fire away, and yes the red dots can be zeroed and are designed to give the correct POI regardless of you head placement on the stock.

A slight movement of the head on a set of peep sights will change your point of impact by 5 to 6 inches on the target. Try doing it while someone is shooting at you and you will see why the M-4's and AR-16's are equiped with optics.

A more accurate system of open sights is the v noch that you will find on hunting rifles. It is harder to not have your head in the correct place with these type of sights.

Obtaining a repeatable sight picture is why the USG trains troops the nose-to-charging-handle method for iron sights.
