Know Your Mount

Step 1. Review the picture above of the AA mount's ring saddle (lower part of the scope ring) and note the position of the split ring. If mounting and using your AA mount for the first time, look carefully to make sure that the split ring is in the center of the saddle ring on both rings. It should look like the picture above. Put your scope in the rings, attach the top of the rings to the ring saddle and position your scope. Place a bullseye or dot on a piece of paper, aim and shoot. Check the pellet's point of impact. If adjustment is necessary, detach the top of the rings and remove the scope. Follow the instructions in Step 2 below.


Step 2. If your goal is only to replace the split rings within the saddle rings, first loosen the Set Screws, then loosen the Adjustment Screws (one on each side), and lift off the saddle ring. The split ring simply unscrews by turning the split ring counterclockwise. Replace by screwing on the new split ring and replacing the saddle ring. Note that the adjustment screws push against the holes drilled in the side of the split rings. You are now finished.

Adjusting for Barrel Droop

If your goal is to make adjustments to correct barrel droop because your gun is shooting low, this may be accomplished by raising the back ring 1/2 turn at a time. Each 1/2 turn counterclockwise (of the back ring) will help eliminate the problem of shooting low. If reverse barrel droop occurs and your gun shoots too high, the opposite adjustment is required. The front ring must be raised higher than the back ring to eliminate this problem. Both adjustments are accomplished by first loosening the Set Screws, then loosening the Adjustment screws slightly and turning the entire ring saddle counterclockwise 1/2 turn. If more adjustment is needed, turn 1/2 turn at a time until the proper height is achieved. The idea is to try to adjust the mount until your pellet's point of impact is within an inch or so of the bullseye (Final adjustments may be made by using the adjustment knobs on the scope). Because the Set Screws and the Adjustment Screws are still loose, you will notice that the rings turn and tilt easily. Now lay the scope in the ring cradles and you will notice that the ring cradles automatically adjust to the scope. Tighten the Adjustment Screws, then the Set Screws after adjusting. NOTE: When tightening the Adjustment Screws, make sure that the split ring stays centered in the saddle ring.

Adjusting for Windage

If your goal is to correct windage (right/left adjustment), the idea is to make the scope "aim" at the point of impact. Example: Your gun is shooting to the left of the bullseye. To adjust, first loosen the Set Screws on both rings, then move the front saddle ring to the left (in the direction the pellet impacts) and the rear saddle ring to the right (the opposite direction). To move the saddle ring to the left, loosen the adjustment screw on the left side and tighten the adjustment screw on the right side. To move a saddle ring to the right, the opposite is done. Because the Set Screws and Adjustment Screws are loose, you will see that both rings turn and tilt easily. At this point, lay the scope in the rings and they will automatically adjust themselves to your scope. Now tighten the Adjustment screws, tighten the Set Screws and replace the top of the rings. Try another shot to see how much correction is still needed. Repeat procedure if necessary. In windage adjustments, the split rings will NOT remain centered in the saddle rings. They will have been adjusted left in front and right in back, or in the opposite configuration.
