Daniel Defense Flip Up Iron Sights

We designed Daniel Defense's Back-Up Iron Sights (BUIS) system to be a low-profile quick-deploy solution that delivers clarity in sight picture and no fuss for the operator. A windage adjustable rear sight and elevation adjustable front sight require no tools to dial in. The BUIS system fits all picatinny rail mounting applications, including rail-height gas blocks.
