One of the reasons that back up iron sights or BUIS systems is not as popular as the red dot or crosshair optics is the amount of practice that has to go into developing a “feel” for how to use the sights.
The Skill Issue
There is a skill needed to be able to develop high levels of accuracy with BUIS. The sights do need practice to master, but they also provide some important benefits that scopes and other types of advanced optics simply cannot offer. A prime consideration is the durability of these sights. They can take a beating when going through the bush or when taken in and out of cases and still continue to be accurate. They also never need batteries, so there is no chance they will let you down out in the field.
Finally, the use of iron sights also helps to reduce the weight of your gun. This may not be important if you are just using it on the shooting range, but if you are walking for miles every ounce starts to be a factor.
The Basics Of Sighting
Using BUIS rather than a scope will take some getting used to. However, once it is mastered, this is a great way to enjoy old-school target practice or hunting experiences.
The biggest mistake that most people use when returning to iron sights or trying them for the first time is to focus on the rear sight. Instead, focus on the front sight exclusively, using the rear sight only necessary to get the front sight in the notch for accuracy.
It is always a good idea to start target practice with the iron sights at a shorter distance than with a scope. Without the enhanced visual effects of the scope, getting the hang of the sights without struggling to see the target will allow you to master the technique before extending your distance.
