Designed from the start with the goal of creating the perfect back up iron sights for SBR owners, the Bobro Engineering LowRider sights are the lowest profile and lightest weight sights on the market today. Sitting at roughly 2/10ths of an inch thick, these sights will not interfere with optics, night-vision, lights, or lasers, allowing shooters to make the maximize their accessories while maintaining back up sights. Despite their minuscule dimensions, they maintain plenty of full sized features such as locking positions with push-button, locking windage and elevation adjustments, and they sit at standard AR heights! These sights are just at home on a full sized rifle in place of more traditional BUIS, making them perfect for any shooter wishing to save weight without losing capability!
