An AR-15 quadrail is a four sided Picatinny hand guard designed for AR-15 rifles, providing mounting surfaces on the top, bottom, and both sides for accessories like lights, grips, lasers, and bipods. It works with AR-15 upper receivers, barrels, low profile gas blocks or standard front sight bases, gas tubes, and delta ring assemblies (for drop in styles). The quad rail’s ideal for tactical and custom builds, offering maximum flexibility for accessory attachment and enhanced handling.
