Most Important Characteristics of AR 15 Iron Sights to Consider When Buying Them

Here are some of the main features of AR 15 iron sights that you need to highly consider when you are looking to purchase them:

  • Attachment system capability

Not every metal sight will fit on just any AR 15 rifle system. You have to mount them on gun rails that they are compatible with. Picatinny Rails and Weaver Rails are probably the two most common rails that people will purchase for AR 15 rifles these days. So make sure you know who your AR 15 gun rail manufacturer is and buy an iron sight that will fit on that particular gun rail.

  • Speed of deployment

When you are in a tactical situation and you suffer a scope failure you could be left with a useless weapon if you do not have iron sights that you can quickly switch over too. The best iron sights for your AR 15 rifle are the ones that can be put into action quickly should you need them. The best metal sights are ones that ‘flip’ into position with the slight press of a button or are what is known as angled sights. These angled sights come into play when your gun is turned at a slight angle to line them up with the barrel.

  • Store out of the way

One of the biggest complaints from shooters about having secondary sights on a weapon is that they get in the way. Comfort is a big factor when shooting so you certainly don’t want your iron sights being a hindrance as you shoot. Metal rifle sights such as angled sights and flip up sights we discussed previously will fit the bill nicely here too. Other types of folding metal sights will help keep the sight out of the way until it’s needed too.

  • Adjustability

You may not be able to do all of the fancy sight adjustments that you can do with on a scope with metal gun sights but you still want to be able to sight them in. That is why the best iron sights will have some capability built into them to adjust for windage and elevation. So look for this capability when choosing which AR 15 iron sights you will purchase.
