AT3 Tactical Leos Review – Friendly AR-15 Optic

AT3 Tactical Leos

Before beginning with the formal AT3 LEOS Review, have you ever wondered why these red dots are awesome? Well to be precise, there are four main reasons for this, i.e. unlimited eye relief, co-witness, parallax free, and allowing the users to keep both the eyes open. In this AT3 LEOS Review, we try to cover everything related to AT3 LEOS.

Unlimited Eye Relief:

Unlike other sights, these red dots amuse the users with maximum eye relief. This means that there will not be any set maximum or minimum distance that you will need to mount from your eye.


It depends on you how you choose the height of the red dot to co-witness your irons. Therefore, even if you will have the red dots being down you can have your irons. Lower 1/3 enables the user with more room while the absolute co-witness places dot on irons.

Parallax Free:

Red dots are parallax free which means red dot will move along you and the point at the same target simultaneously. Therefore, you need not have a super-accurate position to get the right shot.
