Still, I’ll do well to highlight all the essential features of these iron sights, the pros and cons, and what you should be looking out for when getting an iron sight.
Before we delve into the best iron sights for your AR-15, let’s first understand what an iron sight is and the different types of iron sights for AR-15s.
Iron sights are systems of shaped alignment markers (usually metal) used as a sighting device to assist in aiming a firearm device.
Iron sights give the shooter a better aim for his target. While there are sight devices for rifle, many people – especially those old-heads whose first shooting training were with iron sights – still prefer iron sights as the preferred sighting device.

Heights (same plane gas block height, micro): Although different iron sights come in different heights, you need the front and rear sights to be the same height. When the rear and front sights are of the same size, it helps in your aiming and shooting because one sight doesn’t obstruct the other. Front sights come in two heights: the gas block heights and the same plane heights.
Are the sights fixed or folding? Each type of sight has its advantages and disadvantages. The fixed iron sights are unmoveable and so, therefore, are always there to provide you with immediate backup when you need them. The folding sights are incredible, but they can sometimes mess up in the middle of a critical shooting.
The visibility of the sights: in low-light situations, you need to have an iron sight that you can easily see in the dark. To fix the visibility issue with your iron sights, you should do either of these two things: 1) get sights with tritium, a gas; 2) get hi-visibility front sight posts.
