Proper Iron Sight Picture?

[BiGB808]

Hell is it site..or sight?

I did a few searches for it..couldnt find it..Look in my Herstal manual..nothing!!??

Do the rabbit ears wan tto barley touch the top ring of circle?


And why in the hell cant you do more then 1 search every 60 seconds?

thank u for any help

its sight. and i dunno i just put the front sight in the middle of the peep sight and place it on the target.

This is from the M16 Marksmanship manual, but it is the same for the FAL. Your intended target should be right on top of the front sight post.

The front sight should stay in focus within the sight picture...just as Tacs photo suggests.
Think of it this way, imagine it's a small optic sight with imaginary cross-hairs. The vertical hair goes straight down through the center of the front sight post, while the horizontal lays across the top of it.

6 o'clock or center mass?

Don't over think it. Your eye will naturally try to center whatever you are focusing on in the center of the aperture (rear sight). So focus on the top of the front sight blade and let your eye do the rest.

The MK1 MOD O eyeball can detect differences of as little as 1/5000 of an inch under ideal conditions. This situation is created with a small aperature under bright light conditions (think National Match sized apertures and sight blades). You lose some of this precision with the larger apertures common on battle rifles, but the larger aperture allows much more light thorugh to the eye and makes them usable in lower light conditions.

On a rifle with a flip up aperture, like the M-16A1 and A2, the short range aperture is larger as less precision is required and low light shots will normally occur at shorter ranges to correspond with shorter visual detection and engagement ranges. The longer ranged aperture is smaller to allow greater precision at the cost of requiring more light to see things clearly.

With regard to where to hold, it depends on your target. On a round bullseye target the most precision tends to be acheived when you hold the sight blade under the black bullseye in a 6 o'clock hold. If you can focus well on the front blade, you can maintain a consistent amount of light between the blade and the bottom of the bull (basically maintain as thin a section of light as you can still see) to minimize vertical dispersion. Similarly, if the front sight blade or post is the proper width, you can also maintain an even spacing between the edge of the post on each side and the edge of the target. This will reduce horizontal dispersion to a minimum. At really long ranges you end up doing this with the target frame, not the target.

The end result is that under ideal conditions with a good set of eyes, 1 MOA precision is possible.

In the field, a center hold is needed for practical reasons since not every target is accommodating enough to have a correctly sized black bullseye painted on it. However, if you zero your rifle to impact the center of the bulleye at 100 yards with a 6 o'clock hold using a common 100 yard small bore rifle target, you will actually be zeroed 4" high at 100 yards. With either a 7.62mm 150 gr FMJ (at about 2800 fps) or the 5.56mm 55 gre FMJ (at about 3100 fps) sighting 4" high at 100 yards gives you a 300 yard zero.

So in short, with common military ball rounds zeroing with a 6 o'clock hold on a 8" diameter bull 100 yard small bore rifle target works very well in establishing a 300 yard zero with the center hold you will actually use in the field.

Ok, seeing as that's been answered, here's my 2c for the other question:

site - situated somewhere: building site, website

sight - to do with the eyes: front sight, rear sight, eyesight

Gunsite - a site where sights are used

Savvy?

I like to but the bullet right on the top center of the post. None of that 6 o'clock hold stuff for me!

[Deltaten]

The "6 o'clock" or even the "flat tire" hold is preferred for black bullseye targets at distances where the FS would obscure the bull; IF it was held center. I prefer the center hold, regardless of target

Dakota's correct! The human eye is capable of exacting measure, and wil naturally find the center of a circle. It like round things, both naturally occcuring and man-made

Best,

my site sight suit trilux is hitting @ 5 on the clock, ran out of lite light, front screw up or down ? right screw in or out ?range was 30 yards
Thanks for help

Lever back, front screw clockwise.

Years ago, when I started High Power shooting, I learned that there were two basic schools of thought..."6:00 Hold", and "Navy Hold".
Resting the black on top of the front sight, as with the 6:00 hold can be problematic as not all blacks are the same diameter. But since your eye can easily find the center of a sphere, the Navy hold (dead center) tends to work better and more consistently for most.
Thats certainly the case with me.
