An AR15 quad rail pistol kit is a complete set of components for building an AR-15 pistol, featuring a quad rail handguard with four Picatinny rail sections for mounting accessories like lights, grips, and lasers. The kit typically includes a short barrel, upper receiver, quad rail hand guard, pistol length gas system, bolt carrier group, charging handle, lower parts kit, buffer tube, and pistol brace. It works with AR-15 lower receivers and standard AR-15 parts, making it ideal for compact, customizable pistol builds focused on accessory flexibility and tactical use.
