A 14″ handguard is a long rail or polymer handguard designed for AR-15 and AR-10 rifles with barrels typically 14.5″ or longer. It works with mid-length or rifle-length gas systems, compatible upper receivers, low-profile gas blocks, and gas tubes. The 14″ handguard provides extensive space for mounting accessories like lights, grips, and optics, offering enhanced control, customization, and stability—ideal for tactical, competition, and precision AR-platform builds.
