# Issue with IK, Left Hand, ADS

This problem typically occurs if there's some scaling applied to either IK dircetly or weapon-related points.

## Reason 1 - MasterIK scale

Make sure that MasterIK game object (child of the head bone) **does not** have any scaling applied:

You can also check other IK game objects, like RightHandIK, etc. But most likely the issue is with the MasterIK object.

## Reason 2 - Weapon Scale

If your weapon prefab uses scaling, causing the Aim Points to be scales as well, the aiming will be broken.

### How to fix?

Make sure that your weapon is not scaled directly, instead, scale the gun mesh only [Weapon setup](/fps-animation-framework/tutorial/getting-started/weapon-setup.md#step-2-create-pivot-and-aim-points).
