The distance at which you can see with any particular optic is based on many factors including the terrain, weather, the size of what you are trying to see, your eyes, and the time of day. Trying to see a steel silhouette at 1,000 yards will be very difficult with a 4x scope. If you are looking to see and engage targets at that distance, you should look for higher magnification and a larger objective lens (56mm). Although you would also need to consider other factors such as the quality of the glass, the capability of your rifle and ammo, canted bases or mounts etc. Email us at Techsales@opticsplanet.com for further assistance.
