AR-15 handguards and accessories set the rifle's handling, rail real estate, and weight balance across 3-Gun and USPSA Multigun stages. Free-float handguards stiffen the barrel for accuracy, while M-LOK and KeyMod mounting slots let you place lights, bipods, and barricade stops where your stage plan calls for them. Options include slim, long, and light-weight handguards, rail sections, and hand stops, with barrel nut and gas system compatibility to confirm.
