Buying Guide When Choosing the Best Flip Up Sights for AR 15
Folding or the Fixed Type
If you do not intend to use much of the optics, the fixed type sight could serve you well. These are not flippable, no moving parts and always ready for your aim. However, they can get in the way of the optics if you want to mount one. The folding types are more flexible, flippable and some varieties even have adjustable center sights.
The best flip up sights are those that cannot be easily damaged by rough use so construction should be a priority. Common materials for these are aluminum, steel and polymer or sometimes a combination of these. Steel is seen to be the strongest material but aluminum is lighter and rustproof. Polymer flip up sights are also lighter but these are not as durable as the steel and aluminum made sights but cheaper.
The aperture sight is actually the peephole of a sight and this is very important because this can make or break your accuracy with your rifle. If your goal is to use your AR15 for short range shooting and for quick target acquisition, a sight with bigger aperture could be ideal. Smaller aperture, on the other hand, is best for long range shooting because it’s already zeroed in right on target through its small hole area.
Optional Sight Visibility
If you have poor eyesight especially on low light conditions, then you may consider having the best flip up sights for AR15 equipped with a sight visibility mechanism. And by this, the example we can give is the tritium. These are small vials that gather light during the day and glows in the dark during low light conditions. Basically, it can help you focus on your target with illuminated light right on the aperture.
Now we take you to the greatest selection of flip up sights that have been proven to be accurate, efficient and popular among AR 15 shooters.
