Frequently Asked Questions - ASV LEICA

What is the ASV system on a Leica scope?

The ASV (Absehen Schnellverstellung) is a quick reticle adjustment system allowing rapid adjustment of the point of impact according to distance, with a lock to prevent misadjustment.

How to lock or unlock the ASV adjustment?

Turn the lower turret (2) 90° clockwise or counterclockwise. The open or closed padlock symbol in the window indicates the status. For proper engagement, it is possible to turn slightly beyond.

How to perform shot correction with a standard mount?

Aim the weapon to center the target in the bore, unlock the ASV, then look through the scope and adjust the elevation and windage turrets to align the reticle with the target center. Test and repeat until correction.

Why use a forward inclined mount?

An inclined mount (e.g., 10 MOA) provides additional adjustment range of about 29 cm at 100 m, useful when the standard travel is insufficient for longer distances.

How to extend the ASV correction range?

Loosen the fixing screws, lift the upper turret, turn it to increase the clicks (e.g., from position 5 to 7), then lower and tighten. This adds travel in one direction but may reduce travel in the other.

How to reset the ASV scale?

Lock the ASV, loosen the screws, lift the upper turret, set the adjustment ring to zero (mark in the window aligned with the index), then lower and tighten the screws.

Where to find the ballistic calculator for the ASV?

The ballistic calculator is available on the Leica Camera AG website. It calculates ASV adjustment values based on caliber and load.

What to do if the adjustment range is insufficient after firing?

You can use a forward inclined mount (10 MOA recommended) or extend the adjustment travel by moving the upper turret (see extension procedure).

How to maintain the Leica ASV scope?

Clean the lenses with a soft microfiber cloth. Avoid chemicals. For repairs, contact Leica after-sales service.

What accessories are provided with the ASV scope?

The delivery includes an Allen key SW 2 mm for turret fixation. The user manual is available as a PDF.

DELIVERY CONDITION

When delivered, the reticule on your Leica telescopic sight is set to the mechanical center of the total adjustment range. The reticule adjustment scale ring (3) is at a value of "5". This setting guarantees a maximum adjustment range (approx. 50cm / 100m) in both directions when zeroing the telescopic sight on the weapon.

LOCKING AND UNLOCKING THE ADJUSTMENT MECHANISM

The elevation turret on Leica Magnus telescopic sights has a lock to prevent unintentional adjustment. To lock and unlock, the bottom knurled dial (2) can be turned by 90° clockwise and anticlockwise. The current locking position is clearly indicated by a corresponding symbol (2.b).

Note:

Note that the bottom knurled dial (2) can be turned slightly beyond the detent positions to guarantee that it always engages clearly.

ZERoING

Mount your telescopic sight (see telescopic sight manual, p. 6). Make sure the weapon and the telescopic sight are as parallel as possible, so that you need to use the smallest possible adjustment range for zeroing correction.

CoRRECTIoN with STANDARD MoUNTING

1. Aim the weapon so that when you look through the barrel the center of the target is visible in the middle of the barrel. To do this, you should ideally remove the breech.

2. Unlock the elevation turret by turning the bottom knurled dial (2), so that the open padlock pictogram is towards the eyepiece.

3. Look through the mounted telescopic sight and correct the variation in the target position from the center of the target by turning the vertical and/or horizontal adjustment mechanism. Make sure that you do not change the position of the weapon.

4. Then check again that the target pin and the center of the barrel are centered and that they coincide on the target.

1. Fire a test shot.

2. Repeat the procedure described above until any remaining variations in the point of impact have been eliminated.

Note:

Depending on the mounting, after zeroing a limited adjustment range may be available for actual use. If the total adjustment range is not sufficient, it can be extended in the following ways:

a. Use appropriate pre-tilted mounting We recommend using a mounting pre-tilted by around 10 MOA. This mounting provides you with around 29cm on a 100m adjustment range for use.

CORRECTION WITH PRE-TILTED MOUNTING

1. Mount your telescopic sight using a pre-tilted mounting (for example 10 MOA).
2. Unlock the elevation turret by turning the bottom knurled dial (2).
3. Turn the top knurled dial (1) until the scale shows a value of "2.1 (21)". (50-29=21).
4. Unlock the elevation turret by turning the bottom knurled dial (2).
5. Loosen the clamping screws (1.a)
6. Lift the top knurled dial (1) inc. scale ring (3) until it is no longer engaged.
7. Turn the top knurled dial (1) until the scale shows a value of "5".
8. Now press the top knurled dial (1) right down and hold it in place.
9. Securely tighten the clamping screws (1.a)

Now continue as described for rough correction with standard mounting.

b. Extending the elevation turret correction range

1. Set the elevation turret to its default delivery condition (locked, scale value "5" (50 clicks)).
2. Loosen the clamping screws (1.a).
3. Lift the top knurled dial (1) inc. scale ring (3) until it is no longer engaged.

4. Now turn the top knurled dial (1) inc. scale ring (3) until it provides you with an additional adjustment range.
   (For example: The number of clicks from the "5" position to the mechanical stop at "0" is not sufficient for zeroing. You turn the top knurled dial to the "7" position. You have thus gained 20cm of adjustment towards "0".)

5. Now press the top knurled dial (1) right down and hold it in place.

6. Securely tighten the clamping screws (1.a)

Note:

Extending the adjustment range for zeroing can result in a restricted adjustment range in actual use / when correcting the point of impact. If necessary, use a pre-tilted mounting as described under a) to achieve optimum results.

ZEROING THE SCALE

1. The telescopic sight and weapon have been zeroed.
2. Unlock the elevation turret by turning the bottom knurled dial (2).
3. Loosen the clamping screws (1.a).
4. Lift the top knurled dial (1) inc. scale ring (3) until it is no longer engaged.
5. Now set the top knurled dial (1) inc. scale ring to the zero position, i.e. until the zero marker appears in the inspection window (2.c) and coincides with the index point (4).
6. Now press the top knurled dial (1) right down and hold it in place.
7. Securely tighten the clamping screws (2.a).

Note:

The zero position on the elevation turret scale should always correspond to your minimum zeroing distance as the elevation turret does not have a negative adjustment range.

LEICA ELEVATION TURRET BALLISTICS CALCULATOR

On the Leica Camera AG home page you will find our elevation turret ballistics calculator. This enables you to determine the relevant elevation turret adjustment values for various distances depending on the caliber and charge. To enjoy the full benefits of the Leica elevation turret easily and accurately, we recommend using this calculator.
