Choosing Your Sight
The See All Open Sight is quite an excellent idea. Unlike all other open sights used on firearms (or scopes, for that fact), this sight doesn't have any eye relief or exit pupil requirement. This alone makes it ideal for the marksman who doesn't want to deal with an angry gun owner. This sight also allows you to work longer distances than you can with a typical open sights system. This means faster target acquisition, more accessible and quick targets.
The See All Open Sight was designed for the US Army specifically. It features an internal mechanism that is different from any of the other iron sights used in the military. Instead of having to cock the gun, the user simply needs to press a button on the side of the rail. The sight then locks onto the target perfectly, enabling the shooter to take a shot without worrying about hitting anything else.
The sight also has a couple of features unique to it. One, it uses a pair of small set screws to keep everything closed. Usually, when these set screws get screwed out of their holes in the rail, the sights can "grasp" them and keep the rail closed. However, the sight no longer has any practical use if the set screws continually come out of their holes.
Another unique feature of the See All Open Sight system is the red dot sight. Most iron sights have a small red dot on the front, so if you are using one of these sights, the red dot will be located in the middle of your eye's field of vision. Because of this, it will be much easier for you to align your target and aim at it. If you have very poor eyesight, though, you will not achieve this level of accuracy, as close targets will be difficult to hit at this distance.
The reticle is a relatively small part of the sight, just above the front sight. It lines up with the rifle's bore, providing the sighting with a crosshairs alignment as it helps you line up the front sight with the reticle. Some types of sights will also have other controls or knobs that you can adjust to change the way the crosshairs look on the sight. These sights are most helpful in seeing what elevation you are looking at, which is very different from how optical sights work.
You will also find that there are different ways to use the See All Open Sight system. If you are shooting from an outdoor distance, like at the target range, you must use the crosshairs to pinpoint your target. When you are closer to the person to shoot at, the reticle becomes more apparent, as it is cut into by the wind and is less complicated to align with the bore of the rifle. You do not want to be adjusting your sight when you are shooting, as this can lead to lousy accuracy. If you are taking long shots at the target range, then it is recommended that you use the optical sight, since the crosshairs become less precise because you are further back from the target.
Some gun models have iron sights, and these require no adjustments to the sights at all. These are the best sight to use if you are just learning how to use your gun. You can make the crosshairs more delicate for long shots by moving them closer to the sight's point of focus, which can be done quickly with the red dot sight. However, you must have a clear sight picture to make a shot, with accurate reticle placement on sight itself. This can be done quickly with the red dot sight, but you must have precise positioning for it.
The last kind of sight is the riser sight, which uses elevation adjustments on the vertical and horizontal rails. Risers are available in both iron sights and telescopic sights, and are a great way to get a good look at your target from up close. Since they are adjustable, they can also be used for practice, as well as hunting. For some reason, the riser seems to work better than the other two, even though there is no difference in the size of the actual sights.
