AT3 Tactical Flip Up Backup Iron Sights (BUIS) provide dead-on accuracy, superior durability, and the best value for AR-15 iron sights!
We have 2 different types of sights available:
Rail Height Flip Up Backup Iron Sights – Used when mounting your front sight on the same plane as the rear sight (like when mounting on a free float quad rail).
45 Degree Offset Sights – Allows you to quickly switch between short and long range targets by just tilting your weapon at an angle – ideal for use with scopes.
