There is a shield in there that only refects in the recile only and it has come loose or was never seated right most of these units are sealed and some are nitrogen charged In simple terms it is broke, if under warranty get a new one if not try pleading your case to the sales clerk, because they will probably counter with you dropped it. Right after it is designed to take recoil shots day after day. Al you can do is try.

When is best time to sight in ATN 390?

At night. You can sight in the 390 during the day in simi-darkness with a day light lens cover over the front of the scope. (the snap cover has a small hole in the center for look see during the day) 50 foot room with a target, bench rest and a rifle vise. You'll also need laser bore sight Figure you rifle ammunition ballistic and how many yards before it starts to drop. Set the 390 reticle to the red do on the target one or two inch above. Dead center set up will give you about two hundred yards on center... approx. Now you know this is a static test or sight in. During night because of some distortion and noise from the scope. stewbison
