The BLACKHAWK! Hybrid Folding Sight fuses a solid metal alloy core with an advanced co-polymer jacket to create a lightweight and extremely durable addition to any rifle. Both tough and lightweight, the hybrid construction eliminates excess bulk while providing tool-less windage and elevation adjustment dials.
