Absolute Vs Lower 1/3 Cowitness Sights

AR Iron Sights and Red Dot Sights

Red dot sights is one of the most popular aiming options on modern weapons – providing both accuracy and speed on target acquisition. But like any battery-powered item, they can break, so you should consider backup iron sighting point as additional insurance. Now – if you’re going to have two different aiming systems on your weapon, you’ll want to make sure they work in harmony. This is where “co-witnessing” comes into play.

But these concepts apply to any weapon that uses an iron sight with the lens.AT3 ARO™ Micro Red Dot Reflex Sight

What are co-witness attractions?

Simply put – co-witness refers to the conformity of iron sights with your red dot sights. If your iron and lens are both visible, you should expect them to be aligned (co-witness) with each other when you align the image. This is the basic concept, but in practice it is a bit more complicated, because You can use different types of viewfinders for orange. “Absolute arrogance” and “Less than 1/3 of shrinkage”.

Explain absolute shrinkage compared to lower 1/3

The image above shows the difference between absolute tightness and the lower 1/3 on the AR with both the optical lens and the iron viewfinder.The way you control your type of co-witness is with the height of your sight.Many red dot sights use riser stands for this purpose – for example: AT3 RD-50 PRO red dot sight gives you the choice of mounting height.

• Absolute altitude – Optic mounted at the same height as iron sights or about 2.6 inches above the center of the bore
• Lower 1/3 height – optical mounted A little taller than iron attractions or about 2.8 inches above the center of the bore

Fortunately, the difference between the absolute and lower 1/3 settings is so small it’s barely noticeable. But it’s still worth mentioning.

Suggestion: Absolute degree of contraction is lower than 1/3

So which setup is best for you? Keep in mind that either setup will work, so it really comes down to personal preference. But we’ve asked this question a lot, and here’s what we recommend:

• If you have an upside down iron frame – Go with absolute arrogance. Since you’ll likely be flipping over attractions often, you might as well have your red dot at “standard height”
• If you have a fixed iron aiming point – We suggest less than 1/3 degree cow. This will give you a neat view of the red dot, but you can still drop your sight to use the iron viewfinder if needed.
• If you don’t have an iron viewfinder – technically no shrinkage applies, but when choosing a mount for your red dot sight, go with absolutely cringe setup, because it will place the optical lens at the “standard height” for which the AR-15 is designed.
