AK Sights & Zeroing Guide
Factory notch-and-post sights, front-post elevation, windage drums, rear sight leaves, zero distances, mechanical offset, optic interaction, canted sight problems, and figuring out whether the rifle needs an adjustment or actual repair.
Sight Picture | Elevation | Windage | Rear Leaf | Zero | Alignment
AK sights are simple. The adjustment logic is the part that gets people.
On the traditional AK sight system, the front sight does the actual zeroing work.
The threaded front post controls elevation. The entire front-sight drum moves sideways for windage. Once that mechanical zero is established, the traditional rear sight leaf gives the shooter different elevation settings for distance.
That means the AK does the opposite of several other common rifle sight systems: you normally move the front sight to move the bullet impact in the opposite direction.
Move the front sight opposite the direction you want the group to move.
How Traditional AK Iron Sights Are Laid Out
Threaded vertically inside the front-sight drum. Turning the post changes elevation.
The front-sight post sits inside a transverse drum that can be pressed left or right to establish windage.
The traditional sliding rear sight changes elevation for different range settings after the rifle has been zeroed.
Sight Alignment Comes Before Sight Adjustment
Before moving anything, make sure the group actually represents the rifle rather than inconsistent sight alignment.
On a traditional notch-and-post AK sight picture:
- Center the front post horizontally in the rear notch.
- Keep the top of the front post consistently aligned with the top edges of the rear notch.
- Use the same aiming reference for each shot.
- Judge the center of a group rather than chasing individual holes.
If the sight picture changes shot to shot, sight adjustment just moves the rifle around your inconsistency.
AK Front Sight Adjustment Direction
| You Want Impact To Move... | Move the Front Sight... |
|---|---|
| Up | Screw the front post down. |
| Down | Screw the front post up. |
| Right | Push the front-sight drum left. |
| Left | Push the front-sight drum right. |
You're moving the front sight into the error. Group is left? Move the front sight left. Group is low? Move the front sight lower. The bullet impact responds in the opposite direction.
Use an Actual AK Front-Sight Tool
A proper AK sight tool handles both jobs:
- A threaded wrench turns the front post for elevation.
- A press pushes the sight drum sideways for windage.
Arsenal still manufactures an indexed front-sight elevation wrench for its SLR/SAM and related AK rifles, and purpose-built AK/SKS tools are widely designed to move both the post and windage drum.
Hammer-and-punch sight adjustment may technically move something. It is also a great way to turn a simple zero correction into scratched parts and uncontrolled movement.
Zero Groups, Not Individual Shots
One round does not tell you where the rifle is zeroed.
Use a stable shooting position and fire a deliberate group. Identify the center of that group. Make one measured correction. Then shoot another group.
If you adjust after every individual shot, ammunition variation and shooter error can walk the sights all over the front-sight base.
There Is More Than One Legitimate AK Zero Method
The correct method depends on the rifle, sight system, ammunition and what you're trying to accomplish.
Use the rifle's prescribed zeroing procedure so the rear sight range markings retain their intended relationship to the ammunition and sight geometry.
Arsenal currently sells a dedicated 21-meter AK zero target intended for use with its indexed sight-adjustment system.
Compact AK-type rifles may use a shorter practical zero. Zastava currently recommends a 25-yard zero as a practical starting point for the short ZPAP92 platform.
Regardless of the initial method, confirm the rifle at the actual distances relevant to the ammunition and sight system instead of trusting a short-range shortcut forever.
What the Rear Sight Leaf Is Actually Doing
On a conventional AK leaf sight, the numbered settings are elevation references for distance after the zero relationship has been established at the front sight.
The Marine Corps AK manual gives the simple example:
- “1” = 100 meters.
- “2” = 200 meters.
- Additional markings continue the distance scale on rifles equipped with the traditional leaf.
Different AK variants may use different maximum ranges, battle marks, fixed sights or flip apertures. Arsenal currently sells AK-74/AK-100 rear leaves calibrated to 1,000 meters, while compact CR/SFC-type leaves are listed to 500 meters.
Battle Settings Are Not Universal Across Every AK
Depending on country and sight pattern, an AK leaf may carry a Cyrillic battle mark, an “A,” another letter, or a different short-range setting entirely.
Arsenal currently sells Russian AK-74/AK-100-pattern leaves with a battle mark and Bulgarian compact leaves using a different battle marking.
Don't grab one internet chart and assume every rear sight leaf on every caliber and barrel length means the exact same thing. Identify the actual sight system first.
Sight Radius Changes How Sensitive Alignment Errors Feel
Sight radius is the distance between the front and rear sights.
A longer radius makes a given amount of visual misalignment represent a smaller angular error. A shorter sight radius magnifies the effect of the same alignment mistake.
That's one reason compact AK-pattern firearms can feel less forgiving with irons even when the sights themselves are mechanically sound.
Mechanical Offset Exists With Irons and Optics
The sights sit above the bore.
That means the line of sight and the projectile's path are not physically the same line leaving the rifle.
At very short distances inside the established zero, point of impact will generally sit below the line of sight by some portion of that sight-over-bore relationship.
Add a tall optic mount and the offset increases. This is another reason the **AK Optics & Mounting Guide** keeps pushing low, sensible mounting height instead of stacking risers for no reason.
Iron-Sight Zero and Optic Zero Are Separate
Co-witnessing can make the optic and irons appear close to one another in the sight picture.
That does not eliminate the need to verify both systems independently.
The optic sits at its own height. Its mount has its own mechanical tolerances. Its zero adjustment is independent of the iron sights.
Use the irons as a useful starting reference if appropriate. Then shoot the optic and confirm the optic.
Zero Is Ammunition-Specific Enough to Matter
Change ammunition and point of impact can change.
Projectile weight, velocity and barrel behavior all contribute.
Zastava's sight guidance explicitly notes that ammunition from different manufacturers can produce different trajectory and point-of-impact behavior.
If you zero with cheap range ammunition and later switch to the load you actually care about, confirm the zero again.
Does the Front Sight Drum Have to Be Perfectly Centered?
No.
The purpose of the windage drum is to move. A rifle can be correctly zeroed with the drum visibly offset from the geometric center of the front-sight base.
What matters is whether the rifle can obtain and hold a reasonable zero while the sight remains mechanically serviceable.
A slightly offset drum is an adjustment. A drum shoved nearly out of usable travel because the rifle still won't zero is a diagnostic clue.
AK front-sight blocks can show visible alignment variation. If the front sight still has adequate adjustment range and the rifle establishes a proper zero, appearance alone does not tell the whole story. But if the sight must be pushed to an extreme, the post bottoms out, or the rifle still cannot be zeroed, stop treating it as a normal adjustment issue.
If the Rifle Cannot Be Zeroed, Widen the Diagnosis
The Marine Corps maintenance manual treats “rifle cannot be zeroed” as an actual mechanical troubleshooting category.
Its documented possibilities include:
- Defective front sight post.
- Defective or bent barrel.
- Defective rear sight.
- Improperly assembled rear sight.
So if you've exhausted reasonable sight travel and the rifle still refuses to zero, the answer is not “keep turning harder.”
Zero Changed? Ask What Changed on the Rifle
A zero shift deserves investigation if it is repeatable.
Check:
- Ammunition change.
- Front sight post/drum movement.
- Rear sight leaf condition.
- Optic mount movement if using an optic.
- Muzzle-device or suppressor change.
- Stock/cheek-position changes.
- Actual mechanical damage.
The IronKells AK Zero Routine
- Identify the exact sight system and rifle.
Standard leaf, compact peep, aftermarket rear sight, optic, or combination. - Pick the ammunition you intend to establish the zero around.
- Use a stable position and a clear aiming reference.
- Shoot a deliberate group.
Don't chase individual shots. - Adjust the front sight opposite the desired point-of-impact movement.
- Shoot another group and repeat only as necessary.
- Confirm the result at the intended zero distance.
- Check the rifle at additional distances so you understand actual point of aim / point of impact.
- Record the ammunition, zero distance and sight setting.
Group first. Adjust second. Confirm third. Changing the sight after every shot is how you turn normal dispersion into an afternoon of wondering why the front sight drum is halfway into another ZIP code.
What People Commonly Get Wrong
Not when adjusting a traditional AK front sight. Front sight moves opposite the desired impact shift.
No. It is adjustable for a reason. Extreme travel or inability to zero is what deserves investigation.
Rear leaf markings vary by model, country, caliber and sight type.
It means the sighting systems visually overlap. Confirm the optic by shooting it.
Different ammunition can produce different point of impact. Confirm when the load changes.
Once reasonable adjustment range is exhausted, sight, barrel or assembly condition deserves inspection.
The Bottom Line
AK irons are straightforward once you understand which sight actually controls the zero.
Establish windage and elevation at the front. Use the correct rear-sight setting for the rifle and zero method. Confirm with groups instead of individual shots. Confirm again when ammunition or major rifle configuration changes.
And don't obsess over whether the sight looks mathematically centered.
The sight's job is to put the group where you're aiming. If it can do that with normal adjustment remaining, it's doing its job. If it can't, start diagnosing the rifle instead of forcing the adjustment.

Group. Adjust. Confirm.
Zero the rifle you actually own with the ammunition you actually shoot. Everything else is somebody else's target.
