A 9″ Ghost rail is a lightweight, free floating hand guard designed for AR-15 pistols and short barreled rifles (SBRs) with barrels around 9″–10.5″. It features a slim profile with multiple mounting slots for accessories like lights, grips, and lasers, offering a modern, minimalist look. The 9″ Ghost rail works with AR-15 upper receivers, low profile gas blocks, gas tubes (usually pistol or carbine length), and short barrels, making it ideal for compact, customizable AR builds focused on maneuverability and accessory flexibility.
