Using the AMG UH - 1 Gen II Holographic Rifle Sight is easy. First, make sure to install the CR123A battery that comes with the product. Once the battery is in, you can mount the sight on your rifle using the Weaver/Picatinny mount. Adjust the elevation and windage according to your shooting needs. The adjustment graduation is 1/2 MOA, and you can make up to 100 MOA adjustments for both elevation and windage.
When using it in different lighting conditions, you can switch between the four night - vision compatible settings with the dedicated night - vision button. The large viewing window makes it easy to aim quickly.
As for maintenance, keep the sight clean. Wipe it with a soft cloth to remove dirt and debris. Avoid using harsh chemicals as they may damage the holographic display. Store it in a dry and cool place when not in use. Also, make sure to check the battery regularly, as a dead battery will prevent the sight from working properly.
