When every ounce counts our micro flip up BUIS are the only choice. Designed with low profile and lightweight in mind. Easily installed on picatinny rails and even easier deployment. No springs or levers just simple one hand operation. Sights lock into the up position to stay on target when you need them most.

Note: Sights are designed to be mounted on the same plane and will not work with railed gas blocks that are taller or shorter than the rear.
