How to Zero Your Rear Iron Sights
When one thinks about rear iron sights, the first thing that comes to mind is a gun with a scope and a laser aiming point. The second thing that comes to mind is often a laser crosshair marker used for target shooting. While both of these are great options, they have their limitations. In this article, I will discuss the benefits and limitations of using these sights on your rifle.
There are benefits to using rear iron sights on your AR, but there are also some limitations. For one thing, these sights can only be used when you are shooting from a standing position. This means that if you are in a prone position, such as on an easel or some other low and steady object, you cannot use the sights. Also, these sights can only be used while the rifle is in the vertical position, meaning that you have to put it up to benefit from using the iron sight.
Another limitation is that these sights can only be used with rifles that have flat bore barrels. Some of the more expensive ARs may have mohawks, but this is not usually the case. If the scope of your rifle is not adjustable to help with windage adjustments, then it is pretty much useless with these sights. Also, some older models have front sight adjustments, which are not available on rear iron sights.
One option that an experienced hunter may want to consider is a flip-up iron sight, which allows the user to look through the scope in a normal position without having to elevate the rifle. These sights work by having two pins that flip up to expose the front sight post. Then, a secondary iron sight can be placed at the bottom of the flip-up post. Using this type of rear sight gives you access to the secondary sight during your target round without moving the rifle.
With the flip-up and secondary iron sights, it is possible to get the best of both worlds. You can still use your primary sight while still being able to see things through your iron sights. To do this, you need to know what your range is and set your elevation up accordingly. Usually, you should be looking through your magnifier and working from a distance of around seven yards to about ten yards, depending on your target. When you are working from a distance, make sure that the range is not too far away for you to not be able to see the target.
Once you find your range, take a practice shot, and see how far the bullet will travel when you flip your rear sight up to the zero position. Once you have done this a few times, you should be comfortable in knowing how much you should be at the zero position. Now, you can go ahead and prime your rifle with your sight installation kit. If you are using an adjustable range, this can be done in one of two ways: either by screwing in the adjustment screws using a small Allen wrench or installing the adjustment screws and turning them in with a Phillips screwdriver. If you are using a gas-powered gun, you will need to use the screws attached to the charging system.
Once you have done that, take your new zeroing tool and make sure that it is lined up with the sight as closely as possible. Most ranges will not allow any adjustment to the sights until they are at the zero position, but if yours does, you will want to line them up before installing the adjustment screws. Once you have everything lined up correctly, the first thing you will want to do is shoot some ammo downrange to determine what kind of accuracy you are getting. In general, you will get better accuracy at longer ranges because you are shooting at a closer range, thus eliminating some of the effects of wind at shorter ranges. Remember to always wind up your rear sight before pulling the trigger.
Once you have found your desired distance, it is time to put the adjustment screws in reverse to zero the rifle. Remember to keep your finger straight when doing this so that you do not accidentally wind the gun up. Once you have done this, you are ready to fire away!
