The D3G model has four different reticles, allowing you to choose the appropriate reticle for your situation. If you are looking for quick target aquisition, use the larger MOA dots for quicker target acquisition. If you are shooting at smaller targets or longer distances and have more time to find the dot, the smaller MOA dot allows you to see more of the target area and is not as distracting. The D3G has four different sized dot reticles to choose from: 3 MOA, 5 MOA, 7 MOA, and 9 MOA. The D3G has nine different levels of brightness to allow you to adjust the reticle to suit your environment, including two for use with night vision goggles. With the easy to use thumb screw, the integrated mount is compatible with Weaver and Picatinny rails. The D3G has a hard anodized matte black finish.
